POTD: Magritte Strikes Again

_8001440 copy
Magritte Strikes Again in downtown Kuala Lumpur. Nikon D800, 28-300VR

Amidst all of the chaos and panic claiming serious ‘issues’ with the new Nikon D800 (see my previous post) – I think it is important for the photographer to serenely rise above the noise (no pun intended) and remember that ultimately, the camera is a tool, nothing more, nothing less. It enables you or gets in your way. All I can say is that from this image alone, the D800 is capable of delivering some of the most accurate color I’ve ever seen. Normally I’d struggle to get the blue right and maintain the rest of the gamut – not so here. The D800 did it effortlessly, with a lens that isn’t known for the accuracy of its color transmission. I really need to get more Zeiss glass in front of this sensor. MT

Popular Nikon D800 woes, problems, issues and solutions

There’s been a lot of brouhaha on the forums recently about the Nikon D800’s various ‘critical flaws’:

1. The camera stops down in live view, so you can’t see anything!

2. You can’t get a sharp magnified live view image, so it’s no good for critical focus.

3. LCD has a color cast.

Let’s deal with these one by one.

1. I don’t consider full time DOF preview to be a problem, actually. Besides, to achieve critical focus accuracy, you should be focusing with the lens at maximum aperture anyway. One of the advantages of live view is that you actually get to see what minimal DOF looks like, unlike with the viewfinder where the focusing screen limits DOF to somewhere around f4.

2. The live view preview image is heavily, HEAVILY dependent on your picture settings because it provides a PREVIEW. So, set accordingly. Note that picture controls don’t affect RAW images unless you’re converting in NX; the settings are stored as a tag in the metadata. I set my picture controls to maximum sharpening to gauge whether an image is in focus or not, the rest don’t matter. (I have a separate set for video.)

Specifically, see below:

Above with standard sharpening set; below with +9 set. Note the difference, specifically with the text. This is at or slightly beyond 100% view. Problem solved.

3. The color is definitely different to the D700/D3/D3s – if I had to say, I think it renders a little warmer. In the image below, both cameras were set to the same WB.

Regardless, you should not be judging color on the camera’s LCD anyway – all images will have to be processed via a computer anyway, and frankly if you’re spending this much on a camera, why would you want to be cheap on your image processing or computer monitor. It’s like buying a Ferrari but only putting 89 octane fuel in it and wondering why the car feels sluggish.

One final word: these are very minor issues. They aren’t deal breakers, and there are workarounds for all of them. Curiously, users of medium format digital have to endure much more – but we never hear them complain about their LCDs, or lack of live view – despite paying ten times as much. Go out and shoot and stop whining. Ultimately, your skill limits the quality of your image far more than the native color temperature of your LCD ever will. MT

Sushi, and the philosophy of photography

_PM07501 copy

Sushi is a universe in itself – there are so few components that if you get any one of them slightly wrong, the taste will be horrible. But if you get every one of them right, the experience can be magical. Specifically, your fish must be fresh and in season; precisely the right amount of soy sauce should be brushed on to the top, with a little dab of wasabi hiding between the rice and the fish. The fish itself is cut slightly concave so it drapes perfectly over the rice, itself measured to precisely the right quantity to make a mouthful and shaped by hand, not too tightly packed and not too loose, either.

_PM07411 copy

And then there’s the seasoning that accompanies the rice – a mix of mirin and rice vinegar – which must offer the right degree of tartness and sweetness to provide a counterpoint to the fish and soy sauce, but not so much that it overpowers or tastes sour. And this is before we even talk about more complicated creations that involve multiple types of fish, or searing, or additional condiments and seasoning.

_PM07492 copy

There’s a parallel between sushi and photography (and sushi and many other things, actually) – aside from the obvious that it’s art, sushi making requires both technical skill and creativity. There are constraints, but you can work around them. It can be learned, it can be honed by experience, but there’s definitely an element of talent and intuition involved which all great sushi chefs possess. Photographs and sushi both come in small, bite-sized increments – they require little time to create if all the elements come together, and can be enjoyed in moments or contemplated for hours – I’ve eaten sushi dinners with 20+ different varieties served over many hours; I suppose that would be like going through the Magnum annual. Neither photography nor sushi is cheap, either; and mastery can take years.

_PM07485 copy

There’s even an anticipative element to it – the feeling of curiosity before you go to eat (wondering what is in season and came from Tsukiji today) is much like the feeling I get before a shoot; you’re all excited and ready to go. It’s also entirely possible that it’s just me.

_PM07471 copy

The best sushi I’ve ever eaten – so far – comes from a local chef in Kuala Lumpur at a restaurant called Hanare; Kenny Yew is an absolute genius when it comes to creating new things – for instance, seared wagyu with momeji oroshii chili – as a sushi. I need to go at least once a month or I get withdrawal symptoms and the DTs, because I just can’t eat sushi anywhere else now. The few lucky friends I’ve taken there feel the same way. It really is art – some of the pieces make me tingly and others nearly bring me to tears. I’ve eaten things there I never would have though edible, let alone ordered – and loved them. That’s much like how certain exhibitions, art or equipment inspire me to try photographic experiments that work out a lot better than expected.

And best of all, you can mix the two. The lighting conditions at that restaurant are pretty horrible, but they save me a seat at the counter which happens to have a halogen spot over it; I position my sushi carefully to be well-lit. This set might appear the same, but that’s because I wanted a consistent point of view; (and comparison)
they were also shot during the same meal. I discovered one other thing that night: the best color I’ve yet managed to achieve is delivered by a combination of Zeiss glass and Olympus cameras.

I had the ZF.2 2/28 Distagon on the Pen Mini via an adaptor, and was utterly floored by the color when I opened up the raw files on my computer – the sushi literally looked like it had in real life. Every bit of the color, texture, iridescence and freshness was captured. I’m guessing it’s a combination of the fortuitous lighting, the great color and micro contrast of Zeiss lenses in general, and the pleasing color palette of Olympus cameras. Whatever it is, I think I’ve found my perfect sushi-camera.

My parting advice is that if you do get a chance to eat sushi made by a master, do as you would do at an exhibition of photographs by a great photographer: put away your preconceptions, go in with an open mind, and enjoy. You’ll probably be surprised. MT

I just remembered I hadn’t posted an image today. This image has been sitting in the upload queue for some time – it reminds me that sometimes, you don’t need technical perfection for something to work; a sense of fun and whimsy can do wonders, too. MT

How-to: Improving your autofocus performance with the AF Fine Tune setting

Over the last few days and in the light of focus criticality with the Nikon D800, I’ve had a huge number of questions specifically regarding focus precision, and whether there’s anything we can do about lenses that are obviously off. Specifically, how does the AF fine tune setting work, and how does one calibrate their lenses?

1. Make sure your camera has AF fine tune. Any of the newer Nikons or Canons offer this feature, and perhaps other brands, too.

2. Find a suitably well-lit target that you and the camera can focus, and preferably one that’s flat but slightly off-plane to the camera, so it offers a variety of different focus distances. An ideal test chart is a world map on a wall, but with the camera to a slight angle to the wall (i.e. sensor plane is not perfectly parallel.)

3. Use a sturdy tripod, and set single AF. This is to rule out camera shake or false-AF movements from the camera attempting tracking.

4. Perform this test with the aperture set wide open. Stopped down, depth of field will hide focus errors.

5. If you have live view (I believe most cameras with AF fine tune do), then use magnified live view to achieve critical focus and take one shot. This will be your benchmark image – the sharpest that the lens can possibly deliver, when focused perfectly.

6. Switch back to single AF, and viewfinder mode.

7. Defocus the lens between attempts: this is important, otherwise the camera may be trying to move the focus gearing in too small an increment to overcome backlash.

8. Let the camera focus normally, and take a shot.

9. Compare the image from step 5 with the image from step 8 – if they’re the same at 100% size, then you’re fine – move on to the next lens.

10. If the images from 5 and 8 aren’t the same, then adjust the AF fine tune setting – say by 5 notches (if you have +/- 20 notches like the Nikons) and repeat 7, 8, and 9. If it’s better, keep going – do another 5-notch adjustment in the direction that created your improvement. If worse, then go back in the opposite direction. Reduce the adjustment amount changes and keep going. Basically, you want to iterate the process until you match your viewfinder-AF image with your live view focused image.

11. Save the adjustment value – if you can’t save camera settings to a card, you might want to write it down somewhere just in case.

12. Repeat for all of your other lenses.

A special note for zooms: most AF fine tune functions don’t let you input separate values for different focal lengths, so you’ll just have to try both ends of the zoom range and see which is worse; then run steps 1-12. Try to find a compromise setting that works acceptably well for all focal lengths in the range. Or, if you use one particular end of the zoom more than the other, you might want to weight your adjustment to this end of the range. MT

More D800 autofocus observations

After a couple more days of testing, I’ve got more observations on the D800’s autofocus system:

1. I think we’re reaching the limits of accuracy for CAM3500FX, and in fact, any phase detect based AF system. There are just too many parts that have to be precisely perpendicular and in exact alignment to achieve focus accuracy – the AF sub mirror assembly, the AF sensor itself, and the main imaging sensor. If any of these is out of plane by a few microns, then you’re going to see some softness. We’re now getting enough resolution that the planarity of the lens mount relative to the sensor becomes an issue – to say nothing of perfect alignment of optical elements. I believe there was an article posted a while back on the Luminous Landscape about shimming a sensor and how much resolution improved by both on-center and especially in the corners of the frame.

2. Future AF systems will have to be hybrid – i.e. use some form of contrast detect or phase detect embedded into the imaging sensor in order to work around these limitations. It doesn’t however solve the problem of mount planarity or lens element alignment.

3. There are some things you can do as a photographer to counter these limitations, chief of which is use live view for critical focusing, or stop down – or better yet, both. Live view eliminates problems of AF sensor/ sub mirror alignment. Stopping down covers slight sensor misalignment with depth of field.

4. AF fine tune is an absolute must to get the most out of the AF system.

5. Bad news for manual focus fans. I did my mirror alignment and calibration this morning – it was almost perfect from factory, which is a first; however, my joy died after removing the focusing screen. The focusing screen in the D800 is a different size to anything Nikon has yet produced. Worse still, it’s the largest one I’ve ever seen, so you can’t even cut something down to fit – it’ll just drop out. This is a real shame; I can only hope a third party produces replacement screens for MF aficionados.

6. Finally, lenses you thought were fantastic on the previous 12MP FX cameras may now only be mediocre or average on the D800 – you have been warned. MT

The confusion between T-stops and f-stops

f-stop – we all know what that is, right? The size of the hole in the lens that lets light through. The faster the better, and the faster the more expensive. The faster it is, the easier it is to shoot in low light. An f0.95 Leica Noctilux is easily ten times more expensive than an f2.5 Leica Summarit, yet it’s only three stops faster.

That’s all. Right?

Not quite.

_5100_DSC1518 copy
Zeiss ZF.2 2/28 Distagon. Notice how the front few elements almost disappear – that’s because they’re not reflecting anything. This despite a huge diffuse light source – it’s the mark of excellent coatings, and promises a T-stop close to the f-stop.

f-stop is the relationship between the physical aperture of the lens – the effective optical diameter, usually limited by the diaphragm – and the focal length. Specifically, focal length over physical aperture equals f-stop. So a 50mm f2.0 will have an effective physical aperture of 25mm. This affects one property, and one property only of the lens: the minimum depth of field. All f1.4 lenses of a given focal length will have the same depth of field. However, they may appear to have different depths of field because the speed of transition between in focus and out of focus differs depending on the optical formula of the lens. As does the quality of the bokeh. (See my other article ‘A word (or ten) on bokeh’ for more information).

_7052666 copy
The legendary Leica Noctilux.

T-stop (curiously, always written with a capital T) is a number measuring the effective transmission aperture of the lens – in other words, the physical aperture might be f2.0, but how well does the light actually transfer light to the image plane? Why would it even differ from the f-stop in the first place? Lenses are actually black holes: they absorb or reflect or refract light in directions other than the imaging plane. It could be due to poor coatings, or internal polished elements, or simply having many elements – at every air/glass or glass/glass interface, 100% transmission is impossible. There will always be some reflections which decrease the effective transmission factor of a lens.

_5100_DSC1488 copy
The famous Zeiss T* coating.

Modern coatings go a very long way towards ensuring that all light entering the lens makes it to the image plane, with flare reduction and increased contrast as a bonus. However, as lens design gets more complex – take those 18-270mm super zooms for instance – the number of elements required to correct aberrations across all focal lengths covered increases, and so does the complexity of the lens design. Remember, more surfaces means less light transmission.

_D90_DSC7216 copy
Leica 21/1.4 Summilux-M ASPH. Again, note how the front few elements disappear thanks to the coating. Interestingly, this is a very complex design for a Leica lens – 10 elements in 8 groups.

Practically, this means that prime lenses will generally give you a higher shutter speed for a set aperture; it might be a small difference, or a noticeable one. Your f5.6 super zooms probably have a T-stop closer to f8 or f10. Conversely, a good prime lens with few elements and excellent coatings will give a T-stop very close to the actual f-stop.

Example 1: the older Nikon 85/1.4 D has a T stop closer to T-2; the Zeiss ZF 85/1.4 Planar yields almost double the shutter speed for the same exposure, with all other variables constant. The T-stop is around T1.47.

_1KD_MG_0064 copy
Old Nikon 85/1.4 D – note visible reflections off every single element. That’s light that isn’t going to reach the sensor anymore.

Example 2: ignoring the minor difference in focal length, consider the Nikon 105/2.8 VR macro and the Leica 90/4 Elmarit-M macro. The Leica has only four elements. The Nikon, 14 elements in 12 groups. What do you think their T stops are? Unsurprisingly, not very different.

Not all lenses are made equal. And don’t think because there are fewer elements, the lens design isn’t as good. It’s very difficult to design a well-corrected lens with few elements – designs such as the Cooke Triplet and Double Gauss are pretty much as simple as they get. MT

POTD: New car obsession

_8001335 copy
New car obsession. Nikon D800, 28-300VR

On a photographic note: the T stop of the 28-300 is much lower than the f stops would suggest, requiring higher ISO. If you want to know the difference between the two, I suggest you come back later for today’s article 🙂 What you can’t see art this size is that this was shot at ISO 1400 – yes, there’s some fine grain if you look at 100%, but guess what – it could have been ISO 50 for all intents and purposes on the web. Downsizing large images (even if noisy at the pixel level) averages out the luminance noise and leaves you with a much cleaner print than you might think.

A mark of today’s blind consumer society: I was attending the launch for the new BMW 3 series locally; overheard was a conversation between two other customers:

Person 1: “It’s so huge inside!”
Person 2: “Really? Doesn’t seem much bigger than the old one to me.”
Person 1: “But it must be, the salesman said so!”

There’s a moral to this story: firstly, don’t believe everything you read or hear: go and verify it with your own eyes, especially if you’re going to be spending your own hard earned money on it – more so these days, since inflation seems to have had a very visible effect on the pricing of goods. Or maybe it’s the aspiring middle class, or both. If something is fit for your purpose, then go ahead and disregard what others – especially those with a clear bias, like salespeople – are trying to tell you. That’s the whole benefit of choice! Remember: this applies equally to anything, be it luxury cars or cameras. 🙂 MT

A very long term (and final) review: The Nikon D700

_1KD_MG_0064 copy

Bear with me here. The Nikon D700 may be a 2008 camera, (ouch, that’s four years old? Why is he reviewing it now?) and even worse, I received it’s successor – the D800 – on 22 March. (My initial review is up, here) It’s now time to close the book on the D700 – its days as my primary workhorse are just about over; I shot my final assignment with it earlier this week. And that’s the reason why I’m reviewing it – I think I’m now qualified to pass an opinion.

Nikon’s pricing has left a gap in its FX lineup – there’s the D7000 at approximately RM3,000/US$1000; the D300s (though hardly ever bought, and arguably bettered by the D7000 in almost every way) at RM4,500/US$1500 or thereabouts; then we’re into FX territory with the D700 at RM6,300/US$2100 and the D800 at US$3000. Notice how the pricing steps up in nice increments: $500-600 gets you appreciably more camera in every increment – well, perhaps with the exception of the D300s, which is to be replaced soon.

_7049641 copy

The D700 was left in the lineup for two reasons: to clear remaining stock, and to provide an entry level option for FX upgraders. And guess what: according to every dealer I’ve spoken to, it’s still selling just as well as the day it was launched. So why does everybody think it’s obsolete? Clearly, because the successor was launched. Hell, even I’m buying one – but only because my D700 has been shot to death and is on the way out; it doesn’t make sense for me to buy another D700 when I could pay a little bit more, and offer more resolution to the clients that require it.

_7047913 copy

To me, the D700 was a landmark camera: the same amazing low light performance as the flagship D3, no compromises in AF or features – anywhere – at a price that was affordable to the majority of serious amateurs, whilst being robust enough to deal with professional abuse. I had two of them at one point. It was the first camera – aside from the D3 – that I felt turned me, the photographer into the limitation, rather than the camera or the lenses. If you could see it well enough to compose, you could get a useable image. If you could aim the camera fast enough, it would focus. And it would track subjects with unerring accuracy.

_7050874 copy

And from a user’s point of view, that’s the all important question answered: yes, it’s good enough. The image quality is beyond reproach; you get 12 extremely clean, high-durability (more on that later) megapixels – which if used properly, is sufficient for any use. The resolution represents a sweet spot between diffraction limits – f27 is about where it starts to kick in – and depth of field. The large photo sites mean that you have a very high signal-to-noise ratio – coupled with high color accuracy and good dynamic range (that’s what I mean about high-durability pixels). In fact, exposed and processed with care, you can get around 13 useable stops out of the camera – which is right up against the limit of its 14 bit raw files. This does require judicious use of the highlight recover slider in ACR and a little deliberate overexposure (a stop is quite doable) – so you have to plan for it at the time of shooting. In any case, any more dynamic range looks unnatural and flat – remember, screens at best can only display 8 bits of tonal range, and even less for print.

Seiko ‘Fifty Three Fathoms’. Nikon D700, 60/2.8 G Micro

Much has been made of the high ISO capabilities of the D3 around the time of its launch; the same holds true for the D700. It isn’t a camera that’s particularly sensitive to color temperature with regards to noise (for example, the D2H and D200 of the previous generation were, due to IR and blue-channel sensitivity issues). Properly exposed, ISO 6400 is clean, and ISO 12800 is useable. To be honest, if you need any higher ISOs than that and you’re shooting wide open with f1.4 lenses, you probably won’t even be able to see the subject well enough to compose.

_7024121 copy

Bottom line: image quality remains on par with the best of the DX cameras, even the new 16MP and 24MP ones. The latter may resolve slightly more at base ISO, but they lose out on dynamic range, edge integrity, and anytime you need to exceed ISO 800. Color accuracy is always slightly better, in my opinion. It remains to be seen if the D800 has the same pixel integrity as the D700, given the benefit of four years of development. I’m not expecting miracles due to its pixel density, however.

Image quality is the largest factor in the success of a camera as a tool, but usability is right up there, too. Suffice to say that Nikon has been doing this for a long time, and it shows. The ergonomics of this camera are very comfortable, even for extended use, and with larger lenses. In my mind, it balances best with something large-medium – around the size of the 85/1.4, for instance. Larger is a bit front heavy, but still comfortable. If you need more weight, or speed, there’s of course the MB-D10 battery pack – with the right batteries, 8fps is possible. (Curiously, 8fps is also possible without the battery pack if you select flash bracketing, single-shot mode, and hold down the function button to select a 9-frame burst.)

_7022462 copy
Teatime. Nikon D700, Zeiss ZF.2 2/28 Distagon

There are a lot of nice little touches here:
– The metering mode switch is still my favorite of any camera; it’s easy to flip to spot when required, though that’s seldom because the 1005 pixel RGB meter is usually spot on. One doesn’t actually appreciate just how accurate this meter is until you use something else.
– Viewfinder blind and eyepiece lock
– The built in flash. Many people question why you’d want to have this on a professional camera, but clearly those people never work with speed lights – I do all the time, and it’s invaluable to use as a remote commander.
– My Menu.
– The ability to use the multi-selector center button to instantly zoom playback images – to check for sharpness – then toggle between the same magnified point on successive images with the command dial.
– Tethered port caps, finally. Too easy to lose the little screw in plugs on the last generation, and much too expensive to replace.
– The battery grip communicates via a series of small contacts on the base of the camera, and doesn’t require you to remove the original battery and battery door: it’s functional with them still in, and much easier to store and put on/ take off.
– Weather sealing – though I wouldn’t complain if it were fully gasketed like the single-digit cameras, it can still survive a pretty serious downpour unprotected.
– Programmable buttons. Give us more, please.
– DX crop mode – useful when you need more reach in a pinch, but will be better if there was more resolution to support it.
– AF fine tune – very, very important with fast lenses.
– Rangefinder with arrows to tell you which direction to turn the lens in; helpful for manual lenses.
– The LCD is actually good enough for you to be able to judge critical sharpness, and with experience, exposure and color.

But there are also things that need fixing, some of which were addressed with the D800:
– Live view is far too complicated to access – rotate drive mode dial, hit shutter. Should just be a button. (fixed)
– AUTO should be an option on the ISO selection button. (fixed)
– It’s difficult to see the entire finder with eyeglasses – really needs a higher eye point.
– DX crop mode – the masking is far from obvious.
– The focus points could be spread out more; often I still have to shift and recompose even using the extreme points. Curiously, the camera can still track subjects even if they move outside the AF points – it uses the color of the subject and the metering CCD to do this.

_7046623 copy

Let’s talk a bit about AF. Simply, it works. I use either single point mode, with 11 selectable points – when shooting static subjects, and then switch to 3D-tracking with 51 points on the back toggle switch when shooting action or photojournalism. Once you lock on to your subject with the center point, you can recompose and the camera will automatically track. With fast lenses, AF-C is imperative because of field curvature and small movements in either camera or subject – either situation will rob critical sharpness. AF obviously works better when shooting at 5fps because there’s more information reaching the AF sensor, so it’s easier for the camera to predict where your subject is going to go; it’s still good at 8fps, though. Same underlying 51-point CAM3500FX module as the D3-series.

Battery life is excellent. A standard EN-EL3e cell will last me a day; easily a thousand shots or more, with moderate LCD use. With the grip and EN-EL4a cell from the D3 series, you’re looking at easily 5000 or more frames – more than enough for a day of use for even the most prolific photographers. And you can still keep your EN-EL3e in the camera if you’re worried about running out of juice. Simply put, this is the longest-lasting camera that Nikon makes, period.

Nikon D700, 16-35/4 VR

This is actually a very different review to the one I wrote in CLICK! magazine shortly after the release of the camera; I was shooting with a D3 at the time, and didn’t feel that impressed by the camera. But I think I was missing the point: the fact that I wasn’t really missing anything, either, should have been more impressive: flagship performance for almost half the price.

Four years later, I’ve shot nearly a hundred thousand frames between two D700s; both have performed nearly flawlessly. My primary body is throwing the occasional black frame, which suggests a sticky shutter issue. I’m loath to send it in for replacement because my camera is also quite heavily modified, which I’m afraid Nikon will undo if it appears at their workshops. At one point, I was shooting all Zeiss manual focus glass; I discovered the hard way that the viewfinder wasn’t really up to the task of focusing accurately with very fast lenses. My finder has a new screen – a Type J bright matte with micro prisms and split-prism from the F6; it doesn’t fit natively so it had to be filed down. The screen has been perfectly shimmed to be planar and perpendicular with the sensor, and the mirror zero return position and alignment adjusted for the same. Basically, as close to perfect WSYWIG as possible. I’ll probably have to go through the same process again with the D800, but I doubt I’ll bother with the focusing screen as I prefer the Nikon AFS f1.4 lenses these days.

It’s time to answer the inevitable question of D700 vs D800: it’s not as clear cut as you might think. Yes, the D800 offers higher resolution and video but at the expense of per-pixel noise and demands on lenses and technique; in that sense it’s a much less forgiving camera. You’re also giving up the potential of full resolution shooting at 8fps. Ergonomically, both are good; the D800 takes a slight edge due to refined controls, however I personally find the D700 grip more comfortable. The D700 is more of a general, do-anything, go-anywhere camera, but the D800 is a specialist tool that can produce amazing results – under the right conditions.

Although both are clearly interchangeable from a function point of view, if we examine the strengths of each camera, I think the balance splits as follows.
D700 if you:
– Do not make prints beyond 2×3 ft, or use images for digital purposes only
– Shoot a lot of sport or other things that require high frame rates
– Aren’t willing to invest in the best glass or technique

D800 if you:
– Need the resolution for large prints
– Need the increased dynamic range
– Need video capability

In the meantime, my D700 goes into retirement as my backup/ high-speed body. I think I know what kind of beast it is now: the Goldilocks camera: not too big, not too small, just right, and incredibly versatile.

A quick note on Nikon D800 autofocus…

Up to this point, I’d been shooting the camera with the same autofocus settings I used on the D3 and D700 – which share the same CAM3500FX AF module. I think I just discovered why the AF system doesn’t seem to be as precise as before.

Previously, I used single point AF-S for static subjects, and 51-point dynamic 3D tracking AF-C for everything else. I could lock on with the center point, focus and recompose, and everything would be fine. It seemed like a good starting point for the D800.

Turns out I was wrong. Single point AF-C is MUCH more accurate and slightly faster than 51-point dynamic 3D. It’s solved a good number of my AF issues. Remains to try it out tonight when the light gets low to see if performance is improved under those conditions too. MT
