ETTR Processing in Lightroom

ETTR Processing in Lightroom

When we shoot ETTR (expose to the right) in bright, harsh light, Lightroom can sometimes get the wrong idea and make a real ‘hash’ of rendering the raw file.

Sometimes it can be so bad that the less experienced photographer can get the wrong impression of their raw file exposure – and in some extreme cases they may even ‘bin’ the image thinking it irretrievably over exposed.

I’ve just uploaded a video to my YouTube channel which shows you exactly what I’m talking about:

The image was shot by my client and patron Paul Smith when he visited the Mara back in October last year,  and it’s a superb demo image of just how badly Lightroom can demosaic a straight forward +1.6 Ev ETTR shot.

Importing the raw file directly into Lightroom gives us this:

ETTR

But importing the raw file directly into RawTherapee with no adjustments gives us this:

ETTR

Just look at the two histogram versions – Lightroom is doing some crazy stuff to the image ‘in the background’ as there are ZERO develop settings applied.

But if you watch the video you’ll see that it’s quite straight forward to regain all that apparent ‘blown detail’.

And here’s the important bit – we do so WITHOUT the use of the shadow or highlight recovery sliders.  Anyone who has purchased my sharpening videos HERE knows that those two sliders can VERY EASILY cause undesirable ‘pseudo-sharpening’ halos, and they should only be used with caution.

ETTR

The way I process this +1.6 stop ETTR exposure inside Lightroom has revealed all the superb mid tone detail and given us a really good image that we could take into Photoshop and improve with some precision localized adjustments.

So don’t let Lightroom control you – you need to control IT!

Nikon D5 Extended Test

Nikon D5 Extended Test

The last week in June saw me in Norway doing something a bit different from the norm – photographing eagles all week with a 500mm prime – real hard work!

But I thought the task would be made slightly easier with the Nikon D5 running with generation 2 firmware; that is v1.10

And after a solid week of shooting my verdict is – WOEFUL!

The auto focus is still as predictable and user-friendly as a sack full of weasels, but what I found truly appalling is the image quality at lower ISO values – and by lower I mean sub-3200 ISO!

Shooting in Manual Exposure/Auto ISO is the most efficient way of shooting any action, especially with long glass,  but allowing the Nikon D5 to choose its ISO speed just highlights its single massive drawback – poor low ISO performance.

The shot above is at ISO 250, 1/2000th sec and f8.  The crop shows the simple adjustments done to the shot inside the Lightroom Basic panel, and as you can see there is nothing untoward there.

But just look at that appalling level of noise in the underside of the wings – as I said before – WOEFUL.

In this next image, we see the same eagle shot at the same time with the D5 (left) and a D4S (fitted with a 400 f2.8, right). Both cameras are in d25 AF mode, 1/2000th sec, f8 and ISO 1100:

Both images have had a ‘zeroed’ process applied to them in Lightroom followed by a process version swap to kill the excess contrast added by Lightroom in the background.

Again there is excess noise under the wing together with detail degradation in the D5 shot on the left.

As a final comparison, here is the same moment in time caught on the D5, D4S and 1DXMk2. All 3 images have a flat, neutralised process in Lightroom with no added output sharpening:

You do really have to view these images at their full size.

On the whole, I have to say that the 1DXMk2 is the worst image in terms of IQ – both Nikons have it beaten to death – which I must admit surprises me considering the ideal lighting conditions.

But as for the two Nikon shots the D4S still produced the slightly better IQ, lens differences aside, there is still slightly more noise in the D5 shot.

The other error in the D5 shot is due to the sack of angry weasels – the auto focus – the shot is not sharp.  But funnily enough the previous frame was:

As ever, the Nikon AF tends to bounce around a little bit. Even though the D5 has the new Multicam 20K system there is still the same problem of subtle focus bounce that I personally try and negate by shooting at f8 – hoping that the extended DoF will mitigate its visual effect.

But it doesn’t always work, and the D5 will still sometimes drop focus completely on the ‘pick shot’ when the eagle hits the water.

Over the course of the week, I tried pretty much every conceivable permutation of Blocked Shot Response/Subject Motion/AF Mode settings that made any sense – and a few that didn’t – and to be honest they were all as bad as each other.  In the end, I settled on BSR/SM settings at default ‘out the box’, and Group AF mode – but that was way less than perfect.

Ole Martins eagles do represent possibly the most testing scenario for any camera auto focus system, but overall I have to say that for this particular job the D5 AF is an epic fail and a retrograde step – the D4/D4S faired much better.

And both Nikon systems get kicked into touch by the Canon system,  but the IQ of the 1DXMk2 lets it down somewhat, especially in comparison to the Nikon D4/D4S.

I’m certain that better IQ can be had from the Canon system if only Canon would give its users a firmware update to record uncompressed raw; something I’ve been banging on about for years.

But this post is about the Nikon D5 image quality at lower ISOs – and in all honesty, it’s CRAP.

Further Nikon D5 AF thoughts:

Typically of Nikon, they bring out another firmware update just after I use the damn thing for a week.  I’ve not tried the new firmware yet but the ‘added AF modes’ of a single row and single column closest point have a certain smack of desperation in my eyes.

I know that OEM AF calibration is done in both the horizontal and vertical planes.  So to give a camera the ability to use its horizontal calculations and to ignore its vertical ones, and vice versa says to me that there is an imbalance between its x and y axis ‘workings out’.  Couple this with forcing the AF to pick the closest point on the subject under that row or column is basically a case of ‘hedging your bets’ even further.

Nikon should have done exactly what Canon did, and simply refine their existing AF system instead of adding a shed-load of these tracking sensors – there are just TOO MANY points resulting in too much information, and any errors between vertical and horizontal are just being amplified.

I cannot find any visual representation of the two new modes, called group-area AF (VL) with 5 points, and group-area AF (HL) with 11 points.  But if they are as described then they will be ignoring the fixed tracking points. If that is indeed the case, and these modes actually give a marked improvement, then the whole system is a waste of time and effort because it is the plethora of fixed tracking points that form the main distinction between the Multicam 3500 FX and 20K systems.

But hey, that’s just my opinion and I’m not really in possession of all the facts yet.

Nikon D7500

Nikon D7500

Nikon D7500

All week my inbox has been inundated with emails from every vendor and idiot magazine extolling the virtues of the new Nikon D7500, why I should want it, buy it, and tell everyone else to do so.

In Ephotozines announcement for example,  they state that the Nikon D7500 sits ABOVE the D7200, launched back in March 2015.  And that would be a logical assumption based on the model number wouldn’t it; the D7500 could be seen as the D7200 replacement, or at least a step up from it.

WRONG !

Nikon have been making basically three classes of DSLR cameras, Basic, Intermediate and Professional/Advanced.  Late last year Nikon brought out the D5600 which sat firmly in the BASIC bracket.

The D5600 importantly has:

  • No DUAL card capability
  • No AI/AIS indexing capability
  • No vertical grip capability
  • Body Only price: around £500

The D7200 has:

  • Dual Card Slots
  • AI/AIS indexing tabs
  • A  vertical Grip capability
  • Body Only price: around £850

The NEW NIKON D7500 has:

  • NO Dual Card capability
  • NO AI/AIS indexing tabs
  • NO Vertical Grip capability
  • Body Only price: around £1300

As far as I’m aware the Nikon D7500 is THE FIRST Nikon DSLR body to cost MORE than £1000 that does NOT allow you to use the FULL range of Nikon current production lenses such as the 50mm f1.2 or indeed any of the stellar AI/AIS lenses available on the used market for little money.

Nikon D7500

The AI/AIS tab on the Nikon lens mount – missing on the Nikon D7500.

The D7200 DOES all the above, and the D5600 does not.

Take the Nikon D7500 and swap the 7 and the 5 around and you get a Nikon D5700 – now that’s more like it!

But Andy you’re talking crap – it’s got the brain of the D500!

Yes – so they say, but it’s still got basically the same AF system as the FX D750 and DX D7200 – the 51-point MultiCam 3500 FXII, not the D500 MultiCam 20K.

But Andy you’re talking crap – it does 8 frames per second!

That’s as maybe – but how long can it keep that up for buffering to a crappy SD card?

Nikon have basically ripped the 20.9Mp sensor and Expeed 5 processor out of the D500 and jammed it into a D5600, together with the AF module from the camera YOU THINK it’s replacing, and decided to charge you more than TWICE THE PRICE.

Nice one Nikon!

Yes, image quality wise the Nikon D7500 should kick the living daylights out of both the D5600 and the D7200 if only because of the D500 SNR firmware that drives its image recording.

But at that price???

Believe me – a used D3S would crucify the Nikon D7500 on IQ alone, with the added benefit of dual CF cards and an FX sensor.

But perhaps you don’t want the glorious wide angle performance afforded you by an FX sensor.  If that’s the case then be sensible with your money and get a D500 – used ones are out there at the same sort of money as the new Nikon D7500.

It just shoots for ever buffering to an XQD card, has AI/AIS capability and can be fitted with a vertical grip.  Then the AF can be revved up a bit more by using a big battery out of the one of the FX pro bodies.

You’ve only got to look at the specs for Nikon D7500 to know it’s something of an epic FAIL!

More ISO Settings Misinformation

More ISO Settings Misinformation

This WAS going to be a post about exposure…….!

But, this morning I was on the Facebook page of a friend where I came across a link he’d shared to this page which makes a feature of this diagram:

exposure

Please Note: I’m “hot linking” this image so’s not to be accused of theft!

This style of schematic for the Exposure Triangle is years old and so is nothing new.

When using FILM the ISO value IS a measure of sensitivity to light – that of the film, in other words its SPEED.  Higher ISO film is more sensitive to light than lower ISO film, and the increased sensitivity brings about larger ‘grain’ in the image.

When we talk ‘digital photography’ however the ISO value HAS NOTHING TO WITH SENSITIVITY TO LIGHT – of anything inside your camera, including the damn sensor.

ISO in digital cameras is APPLIED GAIN. Applied ‘after the exposure has been made’..after the fact…after Elvis has left the freaking building!

Your sensors sensitivity to light is FIXED and dictated by the size of the photosites that make up the sensor – that is, the sensor pixel pitch.

People who persist in leading you guys into thinking that ISO controls sensor sensitivity should be shot, or better still strapped over the muzzle of an artillery piece……..

The article then goes on to advise the following pile of horse crap:

Recommended ISO settings:

  • ISO 100 or 200 for sunny and bright daylight 
  • ISO 400 ISO for cloudy days, or indoors 
  • ISO 800 for indoors (without a flash) 
  • ISO 1600+ for very low light situations 

WTF??? What year are we in – 2007??

And this pile of new 2017 junk is on a website dedicated to a certain camera manufacturer who’s cameras have produced superb images at ISO settings way higher than the parameters stated above for ages.

Take this shot from a Canon 1DX Mk1 – old tech/off-sensor ADCs etc:

Canon 1DX Mark 1 ISO 10,000 1/8000th @ f7.1 – click for the full size image.

ISO settings are at the bottom of the pile when it comes to good action photography – the overriding importance at all times is SHUTTER SPEED and AF performance.

I don’t care about ‘ISO noise’ anywhere near as much as I care about focus and freezing the action, and neither should you guys.

What have the above and below shots got in common – apart from the wildlife category?

More ISO Settings Misinformation

1/8000th shutter speed and an aperture of 7.1 – aperture for DoF and shutter speed to freeze the action – stuff the ‘noise’.

And speaking of ‘noise’ – there isn’t anywhere near enough to screw the shot up for stock sale even at full size, and I’ll tell you again, noise hardly prints at all!

Here’s another ‘old tech’ Canon 1DX Mk1 shot:

More ISO Settings Misinformation

I don’t really want to wheel the same shots out over and over but don’t forget the Canon 5D Mk4 Great Tit at 10,000ISO or 1DX Mk2 Musk Ox at 16,000ISO either!

Don’t get me wrong, when I want maximum Dynamic Range I shoot at base ISO, but generally you’ll never find me shooting at any fixed ISO other than base; other than when shooting astro landscapes.  Everything else is Auto ISO.

So a fan website, in 2017, is basically telling you not to use the ISO speeds that I use all the damn time – and they are justifying that with bad information.

Please people, 90% plus of what you see on the web is total garbage, please don’t take it as gospel truth until you check with someone who actually knows what they are talking about.

Do I know what I’m talking about, well, only you can judge that one.  But everything I do tell you can be justified with full resolution images – not meaningless little jpegs on a web site.

Camera ISO Settings

The Truth About ISO

Andy Astbury,noise,iso

The effect of increased ISO – in camera “push processing” automatically lift the exposure value to where the camera thinks it is supposed to be.

Back in the days of ‘wet photography’, we had rolls and sheets of film that carried various ISO/ASA/DIN numbers.

ISO stands for International Standards Organisation

ASA stands for American Standards Association

DIN – well, that’s ‘Deutsches Institut für Normung’ or German Institute for Standardisation

ISO and ASA were basically identical values, and DIN = (log10)ISO x10 +1, so ASA/ISO 100 equated to DIN 21….nope, I’m not going to say anything!

These numbers were the film ‘speed’ values.  Film speed was critical to exposure metering as it specified the film sensitivity to light.  Metering a scene properly at the correct ISO/ASA/DIN gave us an overall exposure value that ensured the film got the correct ‘dose’ of light from the shutter speed and aperture combination.

Low ISO/ASA/DIN values meant the film was LESS sensitive to light (SLOW FILM) and high values meant MORE sensitivity to light (FAST FILM).

Ilford Pan F was a very slow mono negative film at ASA 50, while Ilford HP5 was a fast 400 ASA mono negative film.

The other characteristic of film speed was ‘grain’.  Correctly exposed, Pan F was extremely fine grained, whereas correctly exposed HP5 was ‘visibly grainy’ on an 8×10 print.

Another Ilford mono negative film I used a lot was FP4.  The stated ASA for this film was 125ASA/ISO, but I always rated it (set the meter ASA speed dial) to 100ASA on my 35mm Canon A1 and F1 (yup, you read that right!) because they both slightly over-metered most scenes.

If we needed to shoot at 1/1000th and f8 but 100ASA only gave us 1/250th at f8 we would switch to 400ASA film – two stops greater sensitivity to light means we can take a shutter speed two stops shorter for the same aperture and thus get our required 1/1000th sec.

But, what if we were already set up with 400ASA film, but the meter (set at 400ASA) was only giving us 1/250th?

Prior to the release of films like Delta 1600/3200 we would put a fresh roll of 400ASA film in the camera and set the meter to a whopping 1600ASA! We would deliberately UNDER EXPOSE Ilford HP5 or Kodak Tri-X by 2 stops to give us our required 1/1000th at f8.

The two stops underexposed film would then be ‘push processed’, which basically meant it was given a longer time in the developer.  This ‘push processing’ always gave us a grainy image, because of the manner in which photographic chemistry worked.

And just to confuse you even more, very occasionally a situation might arise where we would over expose film and ‘pull process’ it – but that’s another story.

We are not here for a history lesson, but the point you need to understand is this – we had a camera body into which we inserted various sensitivities of film, and that sometimes those sensitivities were chemically manipulated in processing.

That Was Then, This Is Now!

ISO/ASA/DIN was SENSITIVITY of FILM.

It is NOT SENSITIVITY of your DSLR SENSOR….!!! Understand that once and for all!

The sensitivity of your sensor IS FIXED.

It is set in Silicon when the sensor is manufactured.  Just like the sensitivity of Kodak Tri-X Pan was ‘fixed’ at 400ASA/ISO when it was made at the factory.

How is the sensitivity of a digital sensor fixed?  By the SIZE of the individual PHOTOSITES on the sensor.

Larger photosites will gather more photons from a given exposure than small ones – it’s that simple.

The greater the number of photons captured means that the output signal from a larger photosite is GREATER than the output signal from a smaller photosite for the same exposure value (EV being a combination shutter speed and aperture/f number).

All sensors have a base level of noise – we can refer to this as the sensor ‘noise floor’.

This noise floor is an amalgamation of the noise floors of each photosite on the sensor.

But the noise floor of each photosite on the sensor is masked/obscured by the photosite signal output; therefore the greater the signal, the larger the signal to noise (S/N) ratio is said to be.

In general, larger photosites yield a higher S/N ratio than smaller ones given the same exposure.

This is why the Nikon D3 had such success being full frame but just over 12 megapixels, and it’s the reason that some of us don’t get overly excited about seeing more megapixels being crammed into our 36mm x 24mm sensors.

Anyway, the total output from a photosite contains both signal and noise floor, and the signal component can be thought of as ‘gain’ over the noise floor – natural gain.

As manufacturers put more megapixels on our sensors this natural gain DECREASES because the photosites get SMALLER – they have to in order to fit more of them into the finite sensor area.

Natural gain CAN be brought back in certain sensor designs by manipulating the design of the micro lenses that sit on top of the individual photosites. Re-design of these micro lenses to ‘suck in’ more tangential photons – rather like putting a funnel in a bottle to make filling it easier and more efficient.

There is a brilliantly simple illustration of how a sensor fits into the general scheme of things, courtesy of digital camera world:

Camera ISO Settings

The main item of note in this image is perhaps not quite so obvious, but it’s the boundary between the analogue and digital parts of the system.

We have 3 component arrays forward of this boundary:

  1. Mosaic Filter including Micro Lenses & Moire filter if fitted.
  2. Sensor Array of Photosites – these suck in photons and release proportional electrons/charge.
  3. Analogue Electronics – this holds the charge record of the photosite output.

Everything forward of the Analogue/Digital Converter – ADC – is just that, analogue! And the variety of attributes that a manufacturer puts on the sensor forward of this boundary can be thought of mostly as modifying/enhancing natural gain.

So What About My ISO Control Settings Andy?

All sensors have a BASE ISO. In other words they have an ISO sensitivity/speed rating just like film!  And as I said before THIS IS A FIXED VALUE.

The base ISO of a sensor photosite array can be defined as that ISO setting that yields the best dynamic range across the whole array, and it is the ISO setting that carries NO internal amplification.

Your chosen ISO setting has absolutely ZERO effect on what happens forward of the Analogue/Digital boundary – NONE.

So, all those idiots who tell you that ISO effects/governs exposure are WRONG – it has nothing to do with it for the simple reason that ISO effecting sensor sensitivity is a total misconception….end of!

Now I’ll bet that’s going to set off a whole raft of negative comments and arguments – and they will all be wrong, because they don’t know what they’re talking about!

The ‘digital side’ of the boundary is where all the ‘voodoo’ happens, and it’s where your ISO settings come into play.

At the end of an exposure the Analogue Digital Converter, or ADC, comes along and makes a ‘count’ of the contents of the ‘analogue electronics’ mosaic (as Digital Camera World like to call it – nice and unambiguous!).

Remember, it’s counting/measuring TOTAL OUTPUT from each photosite – and that comprises both signal and noise floor outputs.

Camera ISO Settings

If the exposure has been carried out at ‘base ISO’ then we have the maximum S/N ratio, as in column 1.

However, if we increase our ISO setting above ‘base’ then the total sensor array output looks like column 2.  We have in effect UNDER EXPOSED the shot, resulting in a reduced signal.  But we have the same value for the noise floor, so we have a lower S/N ratio.

In principal, the ADC cannot discriminate between noise floor and signal outputs, and so all it sees in one output value for each photosite.

At base ISO this isn’t a problem, but once we begin to shoot at ISO settings above base, under exposing in other words, the cameras internal image processors apply gain to boost the output values handed to it by the ADC.

Yes, this boosts the signal output, but it also amplifies the noise floor component of the signal at the same time – hence that perennial problem we all like to call ‘high ISO noise’.

So your ISO control behaves in exactly the same way as the ‘gain switch’ on a CB or long wave radio, or indeed the db gain on a microphone – ISO is just applied gain.

Things You Should Know

My first digital camera had a CCD (charge coupled device) sensor, it was made by Fuji and it cost a bloody fortune.

Cameras today for the most part use CMOS (complimentary metal oxide semi-conductor) sensors.

  • CCD sensors create high-quality, low-noise images.
  • CMOS sensors, traditionally, are more susceptible to noise.
  • Because each photosite on a CMOS sensor has a series of transistors located next to it, the light sensitivity of a CMOS chip tends to be lower. Many of the photons striking the sensory photosite array hit the transistors instead of the photosites.  This is where the newer micro lens designs come in handy.
  • A CMOS sensor consumes less power. CCD sensors can consume up to 100 times more power than an equivalent CMOS sensor.
  • CMOS chips can be produced easily, making them cheaper to manufacture than CCD sensors.

Basic CMOS tech has changed very little over the years – by that I’m referring to the actual ‘sensing’ bit of the sensor.  Yes, the individual photosites are now manufactured with more precision and consistency, but the basic methodology is pretty much ‘same as it ever was’.

But what HAS changed are the bits they stick in front of it – most notably micro-lens design; and the stuff that goes behind it, the ADC and image processors (IPs).

The ADC used to be 12 bit, now they are 14 bit on most digital cameras, and even 16 bit on some.  Increasing the bit depth accuracy in the ADC means it can detect smaller variations in output signal values between adjacent photosites.

As long as the ‘bits’ that come after the ADC can handle these extended values then the result can extend the cameras dynamic range.

But the ADC and IPs are firmware based in their operation, and so when you turn your ISO above base you are relying on a set of algorithms to handle the business of compensating for your under exposure.

All this takes place AFTER the shutter has closed – so again, ISO settings have less than nothing to do with the exposure of the image; said exposure has been made and finished with before any ISO applied gain occurs.

For a camera to be revolutionary in terms of high ISO image quality it must deliver a lower noise floor than its predecessor whilst maintaining or bettering its predecessors low ISO performance in terms of noise and dynamic range.

This where Nikon have screwed their own pooch with the D5. At ISOs below 3200 it has poorer IQ and narrower dynamic range than either the D4 or 4S.  Perhaps some of this problem could be due to the sensor photosite pitch (diameter) of 6.45 microns compared to the D4/4S of 7.30 microns – but I think it’s mostly due to poor ADC and S/N firmware; which of course can be corrected in the future.

Can I Get More Photons Onto My Sensor Andy?

You can get more photons onto your sensor by changing to a lens that lets in more light.

You might now by thinking that I mean switching glass based on a lower f-number or f-stop.

If so you’re half right.  I’m actually talking about t-stops.

The f-number of a lens is basically an expression of the relationship between maximum aperture diameter and focal length, and is an indication of the amount of light the lens lets in.

T-stops are slightly different. They are a direct indicator of how much light is transmitted by the lens – in other words how much light is actually being allowed to leave the rear element.

We could have two lenses of identical focal length and f-number, but one contains 17 lens elements and the other only 13. Assuming the glass and any coatings are of equal quality then the lens with fewer elements will have a higher transmission value and therefore lower T-number.

As an example, the Canon 85mm f1.2 actually has a t-number of 1.4, and so it’s letting in pretty much HALF a stop less light than you might think it is.

In Conclusion

I’ve deliberately not embellished this post with lots of images taken at high ISO – I’ve posted and published enough of those in the past.

I’ve given you this information so that you can digest it and hopefully understand more about how your camera works and what’s going on.  Only by understanding how something works can you deploy or use it to your best advantage.

I regularly take, market and sell images taken at ISO speeds that a lot of folk wouldn’t go anywhere near – even when they are using the same camera as me.

The sole reason I opt for high ISO settings is to obtain very fast shutter speeds with big glass in order to freeze action, especially of subjects close to the camera.  You can freeze very little action with a 500mm lens using speeds in the hundredths of a second.

Picture buyers love frozen high speed action and they don’t mind some noise if the shot is a bit special. Noise doesn’t look anywhere near as severe in a print as it does on your monitor either, so high ISO values are nothing to shy away from – especially if to do so would be at the expense of the ‘shot of a lifetime’.

Canon 5D Mk 4 Auto Focus Performance

Canon 5D Mk 4 Auto Focus

Canon 5D Mk 4

Like Nikon, Canon never do me any favors!

But I do feel that I must say to the world that it ought to give this camera a bit of a break.  It’s had a good mauling in a lot of places, usually by idiots and no-nothings, who keep comparing it to its big brother the 1DX Mk2 – a camera not without its very own set of unique foibles!

The Canon 5D Mk 4 is NOT designed to be a “poor mans” 1DX Mk2.

It’s hardly what I’d call ‘cheap’ in the old purchase price department for starters, so ‘poor mans’ and ‘budget’ are not terms I can easily associate with it.

There are lot’s of things I need to delve into further on this camera to give you guys a fuller picture of the cameras overall performance – most of which is going to involve Calumet or Canon lending me more lenses.

But I can say that I’ve formulated a solid opinion on the Canon 5D Mk 4 Auto Focus performance, and it’s turned out to be a lot better than I’d first imagined.

These are the style of shot that really tells you if your auto focus is working and up to the job:

Canon 5D Mk 4 Auto Focus

“Joey” 1/3200th, f7.1, ISO5000

Canon 5D Mk 4 Auto Focus

“Joey” 1/3200th, f7.1, ISO5000

Canon 5D Mk 4 Auto Focus

“Joey” 1/3200th, f7.1, ISO4000

But before you can start producing the shots you have to go through the tedious bit of testing the AF first.  It was while testing the overall sharpness and accuracy of the AF system that I came across a little problem.

When photographing the old ‘brick wall’ static target I found the system was front focusing by around 40 centimeters at 30 meters.  If I added +4 on the AF micro adjustment (using the 500mm don’t forget) then everything was razor sharp.

This didn’t seem right in my eyes – I’ve never felt the need to use micro adjust on Canon gear to achieve sharp focus on a static target – perhaps I’ve just been lucky!

But after testing this body with another 500mm L IS II, and Calumets lens on 3 other bodies, all tests revealed the same necessary +4 adjustment.

Canon 5D Mk 4 Auto Focus

The difference is quite marked!

  • Bare in mind that all these ‘static tests’ MUST be done with the aperture WIDE OPEN (in this case f4).
  • I always use the high ISO capabilities of a camera to the maximum, which allows me the luxury of shooting at between f6 and f8 to maximise DoF and use a high enough shutter speed to stop the action.  Manual exposure with Auto-ISO is my usual method of shooting with long glass.  A noisy image that is razor-sharp will ALWAYS out-sell a low noise image full of motion blur!
  • At f8 hardly any of the ‘poor sharpness’ (above left) is visible in the image because DoF is doubled from 40cms to over 80cms behind the plane of focus at this distance.
  • If I was to swap out to a shorter lens then the required amount of micro adjustment would be less, and with a longer lens MORE!

However, when we come to photograph the likes of ‘Joey’ we have a BIG problem!

Adding positive micro-adjustment values is basically like adding BACK FOCUS – you are telling the system to focus BEHIND where it perceives sharp focus to be – in other words ‘focus further away’.

So with a head on closing target/subject the resulting AI Servo sequence of frames will all be back focused.  The camera will be focusing behind a subject that’s getting closer – it’ll never work!

What we need is the system to move the plane of focus AHEAD of the subject, so that when the shutter opens for the next frame, the subject and plane of focus are hopefully in the same place.  This is how PREDICTIVE AF works, and cameras like the 1DX Mks 1 & 2/Nikon D4/4S truly excel at it.

Dialing in an opposite value of -4, and using AF Case 4 settings with Zone AF for the AI Servo sequences of little Joey yielded good results, but the level of consistency was still below what I thought was possible.

And it certainly got even less consistent when I changed to Point Expansion or Point Surround AF modes.

But now I’ve settled on a custom setup that is NOT obtainable on any of the fixed AF cases; TS & ADT both at +2 together with -3 AF micro adjustment:

‘Morgan’ 1/4000th f8 ISO4000 & -3 AF micro adjustment

I’ve just uploaded a new video to my YouTube channel where I discuss the performance of the Canon 5D Mk 4 Auto Focus system, and go through A LOT of full resolution images.

Note, some of you may get bored and think I examine too many images – shame on you! There are 4 sequences, and each one represents around 4 seconds in real time and are a ‘buffers worth’ of shots.  So all those boring shots took less than 20 seconds to acquire –  I have to show all the shots in a sequence to illustrate the level of consistency, and I show 4 sequences to prove none of them are a fluke – I DO THE JOB RIGHT – unlike some other reviewers!

You can view it at full size by clicking the YouTube icon bottom right once you press ‘play’, but be warned it’s 36 minutes long!

I’m not finished with this camera just yet I don’t think; I must admit that I do quite like it!

Is the Canon 5D Mk 4 Auto Focus capable of better performance than that of the venerable old 5D Mk3 ?  Yes, it is.

Is the image quality better than the 5D Mk3 – oh you betcha it is, by a country mile and just like the 1DX Mk2 advantage over the 1DX.

Are the G/T algorithms (ISO), sensor and ADC output better – from what I can see that’s a ‘yes’ too; but then I’ve not done any dynamic range testing yet – kinda hard when the only lens you’ve got is a 500mm!

I’m getting used to the ‘touchy-feely’ screen now, but the fixed 7fps HS frame rate pisses me off a bit, I’d like to be able to drop it to 6 or 5 to the AF system even further.

Take my advice and don’t be impressed with the ‘Duel Pixel Raw’ feature – it’s CRAP. It does absolutely bugger-all apart from slow the camera down and produce massive files that are not worth the time or effort.  And you can only ‘work’ them in that clunky DPP software which is a total abomination to try and use!

And old UHS1 SD card tech? The camera would be better with a CF slot in conjunction with a CFast2 slot ‘a la’ 1DX Mk2 – in my opinion of course.

Canon 5D Mk 4 – First Thoughts

The Canon 5D Mk 4

Looking at the Canon 5D Mk 4 for Wildlife & Bird Flight Photography.

Part 1 – First Thoughts.

Canon 5D Mk 4

The other day Calumet asked if I wanted to test the new Canon 5D Mk 4.  I’d just done an autofocus workshop in Birmingham and had been asked about this camera, so I thought it would be a good idea to take up the offer.

I’ve deliberately stayed well clear of any reviews of this camera while waiting for its delivery – don’t want to unbox it with any preconceived ideas do we??!!

I picked the camera up yesterday from Calumet Manchester, replete with the stunning 500mm f4 LIS Mk 2 lens – “Leanne, where’s the other two spare batteries you promised you’d ordered for me?”

The only Canon DSLRs I’ve used over the past couple of years are the 1DX marks 1 & 2, with the occasional ‘smattering’ of 5DMk3 when I’ve been out with clients – so this new offering from Canon has something of a ‘clean slate’ to start with in my eyes.

So it’s a bit of a shame it got off to a bad start when I pulled it out of its case last night and found that Canon STILL haven’t added a viewfinder blind – a major fault with the 5DMk3 in my opinion.

Canon 5D Mk 4What the heck are they thinking?

Canon 5D Mk 4This camera is no 1DX Mk 2, and it’ll be bought by folk who want to shoot landscapes, seascapes, wide-field astro, a bit of studio work perhaps – it won’t be bought by folk like me who shoot big hairy-arsed beasties in zero light at ISO-stupid; yet the 1DX has one!

Come on Canon – think about the little things chaps.

Anyway, here’s the rig Calumet have supplied to me, just to see how far we can penetrate the domain of the 1DX Mk2/Nikon D5…

Canon 5D Mk 4All those stupid straps can bugger off for starters – Jesus, they are a recipe for disaster.  But WAIT – if I take the camera strap off I’ve not got my stupid rubber flappy thingy viewfinder blind….

Now imagine I’m using this Canon 5D Mk 4 camera with a wide-angle lens shooting a low light seascape with a 10 stop ND and a 2 minute exposure.  That strap flapping in the wind and rattling on the tripod legs isn’t going to do much for image sharpness is it…it’s pathetic.

As a Nikon shooter the lack of a proper blind irks the heck out of me, but we’ll put it aside as I’m sure older 5D users are well used to the problem by now.

So moving on…

My two main interests in the Canon 5D Mk 4 are autofocus performance first, and ISO/low light performance a close second – being good at both is a prerequisite for wildlife photography, and in my mind this 5D Mk 4 is pitching its tent on the lawn belonging to the Nikon D810, so there’s a benchmark for it!

Setting the Canon 5D Mk 4 to my normal ‘Canon settings’ I nearly came a cropper before I started!

Not being used to the, shall we say ‘cheaper’ Canon DSLRs I pressed the DRIVE AF Mode button and flicked the front dial one click, assuming that this would shift the camera from the ONE SHOT mode the previous user had left it, to AI SERVO:

Canon 5D Mk 4

Canon 5D Mk 4

But NO…..WTF is this:

Canon 5D Mk 4AI FOCUS…..what’s that all about then?  So I did something that pained me greatly – picked up the manual – and wished I hadn’t.

So we hit the internet, and the the first hit in a Google search was:

Canon 5D Mk 4That sounded so interestingly unreasonable that I tried it – and soon stopped!

Nahh… it’s not for me – unless I’m missing something major!

So just make sure you are in AI SERVO if you or your subject, or both, are moving.

It’s cloudy outside and about 1.5 hours before sunset, but let’s step outside and do my basic ‘car number plate’ AF test in CASE 1, just to see ‘the lay of the land’ with this Canon 5D Mk 4:

Canon 5D Mk 4

If you want to download the full resolution jpegs – 700Mb zip file – please click hereThe file is at my Dropbox, so if this post goes a bit viral then it may take a while to download.

So there are 30 images, no processing done to them at all, and they are all either 5000 or 6500 ISO.

Shot hand held, 1/2000th, f6.3, manual exposure with auto ISO and back-button-only focus. Maximum frame rate was not quite 7fps (well it didn’t sound like it anyway), and I tried to shoot bursts of around 5 or 6 frames.  It was only on the last of these that I was concious of shooting in buffer overflow.

Single Point AF was being used, in Case 1 – which isn’t best suited to this particular job.  But it’s my standard test with any Canon, just to see how far off the ball the camera/lens combo is.

Shutter release priority was set to FOCUS for the first frame, and +1 focus priority for the second and subsequent frames.

And I have to say I’m pretty impressed.  It’s done a heck of a sight better than I was expecting in Case 1.

Yes the shots have some noise and it certainly can’t hold a candle to its big brother 1DX Mk2 in that department, but then again its not been designed that way. Neither do I regard the noise as much of a problem either because it’s evenly distributed and not overly present in shadows.

But from an autofocus point of view the biggest percentage of those shots are on the money so to speak, and where it has gone wrong it’s only by a whisker; always slightly behind the target – that’s to be expected with an accelerating subject and Case 1 Accel/decel tracking of ‘0’, using a long telephoto.

A considerable improvement over the 5D Mk 3 in both noise and AF performance in my opinion, neither do I think the Mk 3 would have managed 30 frames in the same amount of time.

Over the next couple of weeks I’ll be posting more of my thoughts and findings about the Canon 5D Mk 4.  Tomorrow I’ll do some ISO testing and a bit more on the autofocus if the weather and time permit, so expect another post shortly!

And yes, it’s official, Andy HATES the bloody touch-screen!  Boy am I going to get myself in trouble with that – perhaps I’m too old to cope with such fangled gadgetry!

But that is balanced out by the pleasant surprise that the camera allows exposure compensation in manual mode – up to now a luxury presented to nearly all Nikon users, but only 1DX and 1DX Mk2 Canon owners (to my knowledge anyway) – nice one Canon, it’s about time!

Workshop Report and Canon 1DX Mk2 first thoughts

Workshop Report and Canon 1DX Mk2 first thoughts

September 9th to 16th, Norway Musk Ox and Sea Eagles.

Workshop Report and Canon 1DX Mk2 first thoughts

Left to Right: Mark Davies, Sigbjorn Frengen (our specialist Musk Ox guide for Dovrefjell), “Some Bearded Fat Git”, Mohamed Al Ashkar, Paul Atkins and Malcolm Clayton.

All four clients have been on numerous trips to Norway before, but for everyone, including myself, it was our first time in the Dovrefjell–Sunndalsfjella National Park and the magnificent Musk Ox that call the place home.

Firstly, I have to say a massive thank you to our specialist guide for the Musk Ox, Sigbjorn Frengen.

He’s a superb guide, the font of all ecological knowledge, has a driving passion for what he does, is as fit as the proverbial Butchers Dog, and is only in his mid 20’s.  He took guiding a bunch of geriatric old farts like us well in his stride; totally oblivious to the fact that we were all mighty jealous of his youth and fitness and secretly wanted to kill him for it!

And yes, I immediately booked him for the Dovrefjell part of my September 2017 workshop!

Musk Ox are animals not to be trifled with – they may look very benign but they weigh in at between 400 and 600 kilograms and can outrun Usain Bolt with very little effort.  They are quick to temper, but the signs of the oncoming rage are subtle and difficult to spot even at 60-70 metres. Subtle head-shaking and snorting are the main give-aways that you are causing some displeasure:

Workshop Report and Canon 1DX Mk2 first thoughts

A lone female Musk Ox snorts her displeasure at the presence of the photographer. She wants to rejoin the herd but the camera is in her way, so she blows mucus out of nose as a sign of annoyance.  Canon 1DX Mk2 + 200-400 @ 560mm 1/2500th sec @ f7.1 and 16,000ISO – YES SIXTEEN THOUSAND!

 

The above image shows brilliantly my other main task for the week – testing the Canon 1DX mark 2.

Most people know me as a Nikon shooter, and that I have a love-hate relationship with Canon – yes, I’m a troubled person!

I’ve waxed lyrical about the Canon 200-400 f4 many times on this blog and elsewhere, and the fact that I consider the Canon 61 point Reticular AF System to be the best on the planet.

You will also know that I loathe the sensor output of the original 1DX, and Canons daft refusal to give us the Uncompressed RAW Recording capability – spoilt see, Nikon user!!

I managed to get a couple of hours on the Canon 1DX Mk2 back in July and promptly set about testing the improved AF algorithms – by jingo was I impressed.  I was getting 40% less dropped shots on the Canon 1DX Mk2 at 10 frames per second than I was used to at 6 frames per second on the Mk1.

And as for the sensor output in general, the shadows adjustment latitude and high ISO performance – well, it was a revelation.

The Musk Ox above (click the image to view the full rez) has virtually ZERO noise reduction on it – none in post, and LOW on the in-camera High ISO NR menu setting.

Canon 1DX Mk2

A baby Musk Ox lying by its mothers side on a soft bed of lichen, Erica and rare alpine plants. ISO 2500, 200-400 @ 560mm, 1/2500@f7.1

Why use such a high shutter speed Andy?

It’s brain-in-gear time folks – breezy conditions, lowish light levels, hair on the subject that’s over 1metre long, and wispy grass stems – all these move way faster than the bulky Musk Ox itself – under peaceful circumstances of course!. If these little tiny details suffer with motion blur it ruins the image – provided you have a sensor that can ‘deliver the goods’ at the resultant ISO-stupid.

I’m also shooting hand-held off the knee, with and effective 560mm angle of view on a 20Meg+ sensor, so I’ll need at least 1/1600th to combat the shakes, and I am indeed ‘testing’ a camera, so shooting at sub 1600ISO is not doing the job.

I’m using ‘spot AF’ and partial metering, and my AF point is bang in the middle of the point pattern.

This all neatly brings me to my first problem with the Canon 1DX Mk2 – or at least the one I was using – look at this image from a few frames before:

Canon 1DX Mk2

A baby Musk Ox lying by its mothers side on a soft bed of lichen, Ericas and rare alpine plants.

If you examine the two shots closely you see something odd.

At this distance, around 70 metres, the f7.1 aperture should be generating around 1 metre of DoF.

In the first shot the AF pont was pretty much on babys head, but the DoF run-out is a lot greater beyond that distance than it is closer to the camera.  If the shot had been taken wide open at f5.6 then the subject would not be as sharp as it is.  More of babys body should be sharp, and less foreground sharpness.

In the second shot I’ve wavered slightly right, so now the focus point is on mums ass. This SHOULD push the plain of focus further back – and thus that 1 metre DoF.  And it does – a bit! There is still too much foreground DoF.

The point is this, the focus tends to ‘bounce a little’ rather like the fault with the Nikon D4. This was caused, in the D4, by ‘mirror bounce’. But in the Canon 1DX Mk2 I get the feeling that it’s due to a nano-second miss timing between the AF sensor and the mirror starting to move for the next frame.

Why do I think this?  Because if I drop the frame rate from 10fps to 7fps the ‘AF bounce’ disappears completely.

I could put more images up to illustrate my point further but that would be pointless as it could be a fault unique to the camera I was using.  Having said that, there was another Canon 1DX Mk2 with a 200-400 shooting right next to me, and that showed exactly the same characteristics!!

But there is ONE thing I truly loathe on the Canon 1DX Mk2 – and the D5 and D500 come to that – the rear screen resolutions.

They are all too high in resolution.

I understand WHY they have such high resolutions, but when you are shooting stills at long distance, where focus placement is super-critical, they CAN lull you into something of a ‘false sense of security’ when you use them to check fine focus tolerances at 1:1.

You check the images on the camera and they look sharp.  You get back to base and offload the images to your storage drives then review them on a 13″ MacBook Pro with a damn 227 dpi Retina display and the still look sharp.  You get home and view them on your 90-odd dpi 24″ Eizo – and some of them look a lot less perfect!

I suppose with use it’s something you’ll get used to, but if you are moving to a Canon 1DX Mk2 from an older Mk1 or 5DMk3 then bare it in mind and check your images VERY carefully if you’re using big glass under critical conditions.

Anyway, back to the stunning Musk Ox again:

Stormy skies form a backdrop to a bull Musk Ox standing watch over two females in his harem, ready to chase away any other bull that he may consider a threat to his dominance.

“Bam-Bam does Lunch”

Lack of Lemmings meant the Arctic Foxes were still up in the high ground, so with that and a very wet forecast for Sunday we elected to leave Dovrefjell a day early and do the 7 hour drive to Lauvsnes in order to gain an extra day with the Eagles.

Monday morning saw us in the boat at just after 6.30am and myself an “Mad” Mark Davies had one shot weighing heavily on our minds – Backlit Eagle!

Over the remaining days I have to say that we were spoilt something rotten with opportunities for this most enigmatic eagle shot, here is a tiny fraction:

Canon 1DX Mk2

Canon 1DX Mk2 Canon 1DX Mk2The Canon 1DX Mk2 performed perfectly on this job, no one could have asked it to do more.  Shooting this at 10 frames per second was epic as it captures more of the ‘money shots’ with the spray trails.

Here is a continuous burst of 77 raw files at 10 frames per second, from when the eagle begins its approach to when I can’t basically be bothered any more:

Canon 1DX Mk2

And they are tack sharp from the first:

Canon 1DX Mk2

To the last:

Canon 1DX Mk2

 

I won’t say that by the end of the Thursday session it was getting boring, because I never cease to marvel at these awesome birds – but the hit-rate of the Canon 1DX Mk2 was getting a tad monotonous.

While a ‘crossing’ subject is not so taxing on the AF system as head-on subjects, the huge amounts of lens flare you encounter when shooting the style of image are notorious for playing havoc with auto focus.  When you get to the point of maximum rim lighting neither you or the camera can see very much of anything at all, and most older systems will hunt focus for a frame or two if you are not careful with your settings.

I shot sequences like this using both AF Point Surround and 9 point Zone AF – both of which performed superbly.

I’ll have to add a caveat though – the camera only performs this well if your technique is SOLID.  If you struggle to keep your AF group on target, or are just plain bone-idle, and try Large Zone AF or God forbid Auto, the cameras AF system goes into melt-down doing this sort of shot.

And yet AUTO on the Nikon D5 does a very good job at these sequences – weird!

So after a week of working the Canon 1DX Mk2 quite hard here’s what I think:

First, if you own a Mk1 1DX you NEED to upgrade, if only for the much superior IQ of the sensor.

Canon will probably hate me saying this, but the Canon 1DX Mk2 is ‘a bit of an animal’.  You could ‘wobble around’ a bit on the AF tracking with the Mk1 and get away with it.  But the Mk2 will bite you in the bum for doing the same thing – and when you least expect it.

With head-on targets the AF can both surprise and disappoint, methinks there will be a firmware upgrade at some point that will tidy the systems response to rapidly closing subjects at shortish distances.  That’s what happened with the Mk1.

Canon 1DX Mk2

There some other settings I need to play with on this beast of a machine before I feel I can formulate a descent opinion, things that I never had a chance to try in Norway, and others that only occur to me when viewing images on a PROPER SCREEN!

There is more to this ‘box of tricks’ from Canon than meets the eye!

And has anyone noticed just how CRAP the manual is – Jesus, I don’t think I’ve seen such a ‘sketchy’ document since I perused the Nikon D5 manual….sometimes I get the impression that both Nikon and Canon are a little clueless as to how there own gear works!

Makes me smile – and that’s a good thing!  But then again, it’s not my money being spent here – it’s yours.

A big thanks has to go to Paul Smith for supplying his camera and lens for this first evaluation – Cheers Matey!

And as always a big thank you to my clients, Mark, Malcolm, Mohamed & Paul for being such good sports, making a fun group dynamic, and for having a damn good laugh for week – usually at my expense!  Cheers for your continued support guys.

And lastly, Ole Martin – thanks again for yet another great week. Only another 9 months and I’m back for two weeks solid – Christ, won’t that be fun!!!

Nikon D5 Autofocus Test

Nikon D5 Autofocus Test

On Tuesday afternoon I had the opportunity to do a short Nikon D5 Autofocus test, courtesy of Paul Atkins.

Nikon D5 Autofocus

Using Paul’s newly acquired D5, his Nikon 400mm f2.8 lens and his two crackpot Golden retrievers ‘Enzo’ and ‘Raffa’, his large lawn and a couple of tennis balls, I gave the camera some hard work to do.

PLEASE NOTE: as you can see from the publication date, this is an early release test.

Bearing in mind that attentiveness, obedience and eagerness to please, are not traits that figure greatly in either dogs mental make-up; I was pleasantly surprised as to how instructive the exercise was – well done puppies!

On a good run at the camera the dogs cover something like 28 metres in 5 seconds, starting out at around 31 metres away and ending just outside the focus limiter at around 3 metres.

The camera was set to my MANUAL EXPOSURE + AUTO ISO, 1/4000th and f6.3.

I should also stress that there was NO AF FINE TUNE set for these shots.

That silliness has been taken to a whole new level of craziness now – sweet Jesus it makes me so angry!

I set the AF up very much how I’d set a Canon 1DX or 1DXMk2, and then went through the majority of the AF modes.

Dynamic 9, 25 and 72, group, 3D and ‘AUTO’ – and I was totally horrified at which mode gave the best results, and I mean BEST by a country mile!

In this video I go through the full resolution sequence of 27 shots individually so you can see how the Nikon D5 autofocus performs as the two dogs get closer to the camera with every frame.  The images have only Lightroom default sharpening applied and have had nothing done to them except my standard contrast-lowering adjustments.

Don’t be silly – click the YouTube link in the bottom of the above frame and watch it at full resolution on my channel!

Please don’t take this as a definitive test of the Nikon D5 autofocus – I certainly don’t, and neither am I prepared to draw much of a conclusion from it.  But it works!

I know I’m not alone in finding the Auto focus mode to be ‘better’ in terms of consistent focus, but to my mind this should NOT be the case, especially on such a target moving in such close proximity to a long telephoto – even if it is an f2.8.

At this point I’m not going to bother showing the sequences from the other modes, just take my word for it that I was shocked at the distinctly poorer performance using the other modes I tried – except for GROUP, which has never worked well in this sort of situation.

A couple of things to note:

  1. I used the same settings at 12fps and the consistency level dropped by around 45%, so no change in that old chestnut.  The Canon 1DX suffered from it too, but with the limited testing I’ve done on the 1DXMk2, Canons idea of crafting and honing the existing AF system, as opposed to Nikons ‘chucking the baby out with the bath water’, seems to have solved the problem to a greater degree.
  2. The D5 raw files seem to have lost a little tractability in ‘lifting the blacks/shadows/exposure’ – something that I’ve always held typical .NEF files in high esteem for.  This I found quite surprising seeing as the camera was heralded as the ‘Prince of Darkness’.   It’s also the one thing above all else that I despise in Canon 1DX raw files.  But Canon have upped their game considerably on this front with the 1DXMk2.

Seriously folks, it’s like some sort of demented see-saw or merry-go-round with these manufacturers…

The new Canon is coming to Norway with me in a couple of weeks, and Mr. Paul is bringing his D5, so there will be quite a bit of performance testing going on throughout September and October.

Hope these shots peek your interest folks!

Canon 1DX Mark 2

Canon 1DX Mark 2 – a Game Changer?

A couple of weeks ago I posted on my Facebook page that I had been playing around with some RAW files shot with the new Canon 1DX Mark 2 – and my initial conclusion was that the new speed master from Canon was, in my opinion, something of a GAME CHANGER.

Canon 1DX Mark 2

Boy did I get a bit of a thrashing – from Nikon D5 users who have little to no experience of the pre-existing 1DX system, let alone the new one; in other words folk trying to justify the giant lump of cash they’ve just handed over………

What GAME is it that I think the Canon 1DX Mark 2 potentially changes?

For me it breaks down quite simply:

Auto Focus: The Canon 1DX Mk1 61 point Reticular AF system BEATS THE CRAP out of all variants of the Nikon Multi-Cam 3500 AF system when it comes to using long glass on fast-moving targets.

With the caveat that you need to know and understand how to set it up of course!

Image Quality:  Any Nikon pro-body RAW file kicks a Canon 1DX Mark 1 .CR2 file into the middle of the last century.

The Nikon D4/4S sensors produce RAWs that are cleaner in respect of ISO/Noise, greater Dynamic Range (up to a point) and are just plain “more tractable” when it comes to post process; especially in shadow and highlight recovery.

And so “The Game” is quite simple – AF Performance v Sensor Output IQ – it’s simple and straight forward enough that anyone can understand where I’m coming from!

Let’s get something clear from the start – neither Canon or Nikon have seen fit to let Uncle Andy get his hands on either of the new cameras!  The other week I went to a Canon day in Manchester and actually got my hands on a Canon 1DX Mark 2 – but when I went into my pocket and pulled out a 64 Gb CF card the guy from Canon had a hissy-fit and wouldn’t allow me to take any shots – “we can’t allow them to get into the public domain” was his excuse, and he wouldn’t budge.

But one of the speakers, Simeon Quarrie, was kind enough to let me have a play with some of his .CR2 from a project in Africa he’d just completed on the new Canon 1DX Mark 2 – and my chin hit the floor.

I could not believe what I was seeing – the amount of shadow and highlight recovery over-head was insane.  Overall, the shadow and highlight RAW IQ is right up there with the Nikon D4/4S.  Now let’s not get too carried away here; the Canon 1DX Mark 2 .CR2 file is still lossless compressed ( see blog article HERE) and so isn’t offering QUITE what it could do in respect of post-process, but it is A MASSIVE jump in IQ from the original Canon 1 DX.

FFS Canon, grow a pair will you – give the Canon users a firmware upgrade to allow them the option of keeping the uncompressed RAW will you!  It’s not going to cost you anything…

Austin Thomas kindly sent me a couple of RAWs from his new Canon 1DX Mark 2 a couple of days after the Canon Open day in Manchester:

Screen grab of basic raw file adjustment from the new Canon 1DX Mk2 - shot taken by Austin Thomas. Note Shadow Recovery slider position.

Note Shadow Recovery slider position.

In this Kestrel image note the position of the Shadow slider in the Lightroom Basic panel – 100% to the right.  The shot is 3200ISO so yes there is a bit of noise, but I’ve not made any attempt to remove it – the ONLY adjustment made is to the shadow recovery.  Just look at the eye, there’s NO colour noise or pattern noise.

Note Highlight & Shadow Recovery slider positions.

In the Little Owl (L’owly!) shot I’ve pushed things further by putting the Highlight Recovery slider 100% to the left for maximum effect.

This extreme shadow and highlight recovery is almost impossible with Mark 1 RAWs without incurring massive penalties in the form of colour noise and sensor pattern noise, especially in the shadow areas:

Canon 1DX Mark 2

1DX Mark 1 raw file with 100% shadow recovery – note the huge amounts of pattern noise and false green/magenta colour artefacting.  This shot is mine BTW – Austin doesn’t get many of these up his way!

And now it appears that DPReview have done something useful – they’ve been shooting a head-to-head between Canon 1DX Mark 2 and a Nikon D5 (which in itself is NOT useful), but they’ve put some RAW files up that folk can download.

A couple of these files do a very good job of illustrating my point about the Canon 1DX Mark 2, and you can download them HERE and HERE.

Go and download these two files:

Canon 1DX Mark 2

Canon 1DX Mark 2

Bring them into Lightroom and drag the Highlight Recovery all the way to the left, and the shadow Recovery all the way to the right:

Canon 1DX Mark 2

Canon 1DX Mark 2

Now go and look at those tyre barriers – no colour noise or sensor pattern noise.

As a long-time Nikon shooter I find lots of thing that irritate me about Canon – the crackers menu system and the God-awful ergonomics.  But then a lot of Canon users will say the same about Nikon – it’s what you are used to that makes the ‘stuff’ on the other side of the fence look crazy.

But all that is totally irrelevant really – all I’m ever concerned with is AF performance and sensor IQ.  And sensor IQ was the Achilles Heel of the original 1DX in my opinion – simply because I’m used to Nikon sensor IQ.

I choose to use a Mk1 1DX – with its somewhat inferior IQ – over my D4 or 4S – with the better IQ but poorer AF performance – when “the chips are down”.  The chips are down when I know I’m going to be in a situation where “THE shot” could come at any time, and is not going to be easily repeatable.

Seeing as adopting this course of action involves me begging, stealing, borrowing, or God forbid HIRING the gear, it’s a decision I never take lightly!

But the Canon 1DX Mark 2 has alleviated my IQ concerns, and so makes the option a little easier.

FOOT NOTE

The main fault with the Nikon Multi-Cam AF system is a missing user control – Canon call it Acceleration/Deceleration Tracking.  It’s a mission-critical control, and Nikons steadfast refusal to give us access to it means that either THEY are stupid, or that they think their users are.

But the new D5 AF system gives Nikon users access to a control Nikon call Subject Motion – you guessed it, it’s Acceleration/Deceleration Tracking.

Does it work as effectively as Canons – who have been honing and developing it for years?  Who knows….perhaps I would by now if it weren’t for the earthquake in Japan a few week ago.

I seriously hope that Nikon HAVE got it right; but at the end of the day it still doesn’t help me all that much because I can’t put a D5 on the back of a Canon 200-400 – the best all-round wildlife photography lens on the planet!
