Simply far too much smoke and noise about this issue for it to only exist on a couple of cameras. Most just don't know about it due to not having f/1.4 glass, using it at f/4 or using it in only great contrasty light all of the time. *For more info see first thread.

Sorry for making this personal, but why should any of us believe you, respect your words or take you seriously?

You've been making these threads for YEARS - basically since you first got a D800. Yet you still have your D800. If I had a camera which gave me so much grief and only a 40% success rate on focusing, I'd get rid of it. If it's THAT bad, screw brand loyalty and sell it right now.

You've also been inconsistent. You said AF was broken. Then firmware fixed it and it was a miracle. Oh no wait, it didn't fix it and it's broken again. That makes me think that most of the "problem" is in your own imagination or your own unrealistic expectations.

It took me a couple of days to get used to the AF system, and to learn which modes to use in which situations. And I get very high focus accuracy - shooting at f1.4, even indoors, even at close range. It's not perfect, but NO camera is perfect.

The fact you've been at this for over a year now and keep changing your story just makes me start to call your credibility into question. If your D800 just doesn't do what you want, sell it and get something else. It's that simple. There's no need for prolonged questioning and discussion online.

I use it mainly for landscape, which is the main purpose I use it for now...I don't need AF to do this. I would like to use it for other things. The AF firmware update improved it greatly, but I posted after only testing it in a few situations, hastily, discovered that many issues remained. You can stop being a detective now regarding credibility. If you don't believe me you don't need to post it's really that simple, I just see there are many folk with the same problem. If you look back at the 150 replies many folk see what I see, no smoke without fire pal...

This is too much. There is no justification for posting the same thread over and over for two years. You seem to be trying to convince people that the D800 AF is inferior to all other cameras, and pretty much a complete failure. However, your issue seems to be that it sometimes misses focus at f/1.4 with an 85mm lens, indoors (tungsten, CLF?) in low light and low contrast. Get real. The DOF for 85mm at f/1.4 is paper thin.

The technology is what it is. From what I've read, AF operates at an effective aperture of f/2.8 and needs contrast to discern focus. If you can't nail focus at f/1.4, shoot at f/2 or f/2.8. Your background will still be soft.

You would have been hopeless shooting medium format in mid-20th century. If you can't adapt to what the technology can do, find another pursuit. Enough with the redundant posts already.

Robin, wasn't aware you could police how many threads I post on this (over a long period of time) but okay...since the dpreview board allow it I will continue to call nikon out on this issue. It's not just an 85mm lens at f/1.4, it happens at f/2 and 2.8 it's just worse at f/1.4, it's not just tungsten (we call it incandescent) light that it happens in either...The system cannot do what the D3s and D700 did (as I've said over downsizing still reveals the AF faults. So it still exists as a problem; no matter how much you fanboy the camera up, it exists. I think for landscape it is ideal.

Re: Common misconception here

Maybe D3S and D700 really have a better AF, I mean those cameras were designed for action and pj work, while the D800 is a high resolution studio / landscape camera.

Nikon´s technical guide clearly warns that even the slightest changes in composition can lead to an undesired change of focus.

I would have more sympathy with you raising the issue yet again if you posted a sample image (which does not need to be large) demonstrating an AF fault using AF sensibly.

As of now I make it 162 out of 162 posted images on this forum indicating they were not using AF sensibly.

If the issue existed in more than 1 or 2 cameras where are the examples showing this using sensible testing?

The war ended a while ago, and Nikon conceded.

As usual Nikon enacted "radio silence" when this issue was first identified, and as a result allowed this to get out of hand. As a result, people were testing their D800's for the defect, and concluding they indeed had it, on everything from kit lenses to slow zooms to telephoto primes. People trying a D800 at Best Buy were claiming to see the defect just by looking at a picture in the LCD panel.

So I agree that many if not most if the reports of defect were merely ghosts in the closet.

But the people who found this first were seasoned pros and well respected photographers, and long time Nikon users who probably knew far more about Nikon's AF than page whatever on the manual states. And countless others found the defect too.

If Primeshooter says he has a problem, he does. He's not seeing ghost in the closet.

All the action Nikon took, first behind the scenes, then more openly, the research, technical fixes, jigs, etc, would not have been necessary if the answer was as simple as telling people to read page 7 in the manual.  Nikon's actions make your "I have yet see any proof" and "go read page 7" argument foolish.

I had a defective D800. It took 3 tries to fix it. I spoke to people at Nikon in the process. The problem was very real, effected far more than a few bodies. Thom Hogan's math was probably as correct as we're ever going to know as far as how many units were effected, and when it seemed to stop.

But let's blow up your page 7 thing one last time. Using a fast wide prime, wide open, on a tripod, controlled setting. Any target. All three banks, left, right, and, center.

If the subject is such that the AF can't lock, that should be consistent across all banks. We don't need to read page 7.

If the test subject is such that the sensors CAN achieve lock, but incorrectly, the results access all 3 banks should also be the same: all shots should be OOF. Again, we don't need page 7.

BUT, if the center and right bank sensors CAN accurately achieve lock on that test subject, meaning in focus at the focus point, shot after shot, BUT the left bank sensors, while also achieving lock, are OOF at the AF point, shot after shot, then there is a problem not with the subject, but the left AF bank sensors.  It does not matter what page 7 says, even if the subject is one that page 7 says can be difficult for the AF.

So in reality page 7 is meaningless in that with the left bank defect, what ever the target is, when comparing all 3 banks for accuracy, the right will lock on that target and be in focus, while the left will lock but be OOF. Shot after shot, same subject, same conditions.

Page 7 is a guideline as to what subjects the AF can have a problem with. The center may perform differently due to the cross types, but BOTH left and right bank sensors will be equally challenged.

To me, the claim that the D700 has more accurate AF than the D800/E is BS. The AF on my D700 was much less reliable than on my D800E.

It is a matter of your constant moaning about the same old issue that makes it come to my attention.

My D800E handles AF more reliably and accurately than my D700 did. The D800E will work at an effective aperture of f/8 while the D700 could only manage f/5.6. This claim that the D700 was superior is just BS.

Perfect results in low light and low contrast with almost no DOF is more than you can expect from PDAF. Get over it.

I'm beginning to suspect you are on Canon's payroll.

What do you want to solve by continuing this thread? If your camera is defective, do something. Resell it, fix it, or exchange it. If after 150 posts are back at square one, its time to take other avenues in regards to solving your AF issue.

This is a forum, to discuss issues etc, therefore that is exactly what I am doing. More and more people see the thread and it allows me to gauge how many folk have the problem. You okay with that, or can you just go to another thread and ignore this one if it displeases you?

...but to repeatedly "discuss" the same thing and question those who don't have the same problem, more or less insinuating that they are lying isn't normal, it is sort of "trollish".

He is absolutely right.

Do something. Resell it, fix it, or exchange it. If after 150 posts are back at square one, its time to take other avenues in regards to solving your AF issue. Screw brand loyalty, get another camera or another brand if you don't believe in Nikon.

Personally I can't imagine how people can live with a problem and nag/whine about it all the time. What is the point?

May you should check your expectations. Based on the old thread I tried to replicate some of the settings giving some users problems and I can replicate those, but to be honest those are all scenarios described in the manual as having a high chance to cause problems for the PDAF. So maybe the AF is working as intended, you just have the wrong camera for your needs.

Explain to me why downsizing to match D3s and D700 files (12MP) that the AF errors are still obvious? I think that would mean the D800 is worse at focusing...that it's generally worse than the last generation and it's unrelated to resolution. This is the point. It's not unrealistic as all these shooting scenarios I am trying with the camera worked in the last generation.

Post sample images, preferably in raw but definitely with EXIF. This is really getting ridiculous otherwise.

Yes, there is indeed smoke without fire some times, remember, this is the Internet, I bet you that quite a few of the "smokers" don't even have the D800/D800e and are not even interested in, just like to be here puffing. ...and please, don't try to insinuate that there were 150 individual answers agreeing and seeing what you "see".

Hey bud I sold mine 2 d800s 2 years ago to pick 2 d4s and could not be happier. Yes my 2 D800s had big time issues for me with any of my f1.4 lenses. I wanna actually pick up now a brand new D800 E but if the issue still exists I would pass

Did you whine about it for two years? No, you did not. You did EXACTLY what I would have done if I found mine to have a problem. Send it in, get it fixed and that's it. I don't know what was said and shown in that thread or if Leonard's "162 out of 162 posted images" is accurate or if yours is among those, but I don't think anyone is claiming that there is not a single Nikon camera which can have an AF issue. Sh!t happens, regardless which camera or brand you are using, but if it happens then the best is to let Nikon fix it. Whining here on DPR for years won't fix anything, and having an agenda and running a campaign against the D800/D800e is just trolling, not to be taken seriously.

Leonard

How many posts have you seen which demonstrate the fault doesn't exist using sensible testing?

...and how exactly should one demonstrate that?

Are you driving your car to a mechanic just to demonstrate that you are not having issues with it or you do it when there is a problem and you let them find the exact cause and let them fix it?

Or... if your car breaks down on the highway and everyone with the same type of car just passing you then you shout after them that "BEWARE, everyone has this issue you can't drive that car"?

Why  are you talking about cars in a thread about Focus on a D800?

There is a lot of aggression towards people who are having problems with focus on the D800. Leonard has pointed out that no-one has demonstrated the faults by using sensible testing... as if that is a problem with their understanding or skill. I am simply pointing out that, using the same criteria, no-one has demonstrated that their cameras work correctly either. Surely if the cameras work correctly that wouldn't be a problem would it?

(then again i often get right pictures wich means finetuning could have made those pictures bad).

I've been shooting a lot in cloudy days lately, trying to get sharp pictures F5,6-F8 and without VR it's quite challenging my technique. Inspecting the pictures lately, i come across pictures that are very hazy. Then I tried to look for 'motion blur' signs (like tree branches that leave a trail shadow, wich is 100% confirmation it's motion blur.) I also check from front to back if anything is sharp, if so (doesnt matter how far from the true subject), it confirms wrong focus. Then there's pictures that are hazy, but when zoomed into, on still subject, there no direct 'unsharp' indications. Hard to explain. I came to the conclusion D800 often has what I call 'micro motion blur.' Not the kind of blur that my D80 pictures had. Watching a lot of internet pics, I often see this in pictures there also.

I think often 'autofocus failure' is the first though, when it's actually motion blur. To me it feels and seems that to prevent complete motion blur (from handholding, shutter release etc), one needs 2 to 3x shutter speed on D800 as D700. Basically D700 is a lazy camera in comparison, your technique can be worse. That's not to say D800 cannot make sharp images at same shutter speed. But like 'primeshooters quote' (i think?) in the other thread "I take 5 pictures and only 2 are sharp' will most likely happen with shutter speed good for D700 but on the critical barrier for d800 shutter speed. Shooting 1/20 (or lower) to 1/160 one must keep this is mind. This is the shooting range where often 'micro motion blur' occurs. Not your everyday lazy shot motion blur (obvious 'subject trails' in the picture indicating how where and how strong you moved the camera), but the whole picture will look as it's out of focus. Maybe this is still underestemated? D800 requires more discipline.

However i don't doubt left-AF issue, and people with bad AF units in general. D7000 had this issue on a lot of camera for sure, and D800 is sort of it's big brother. But so far as far as my limit wisdom can tell me my D800 is fine focussing wise perhaps only an edge behind D4 (wich obviously is better checked out, can't have a sports camera failing at nailing focus at all, it's everything or nothing in that category.)

This issue is nothing to do with motion blur I can assure you, this is not the reason my images are not sharp. You don't get motion blur if you shoot someone standing still at 1/4000...so let's nip this one in the bud! Many experienced shooters will tell you. It's a general back or front focus caused by the camera not really knowing what to focus on, that can be seen even if you downsize to 12MP meaning the AF module is worse than the D700 and D3s generation by a long shot. They seem to have changed the AF log now, tweaked it somehow with the new system and totally screwed up a good thing!

now I'm sure this has been suggested but here it is again, if the D800 doesn't work for you just get rid of it.  Is it really worth all this hassle?  Life really is to short to worry so much about a camera.

I'm lucky Im satisfied with my D800 and I don't seem to have this issue with any lens including my sigma 35mm 1.4.

What do you want to solve by continuing this thread? If your camera is defective, do something. Resell it, fix it, or exchange it. If after 150 posts are back at square one, its time to take other avenues in regards to solving your AF issue.

This is a forum, to discuss issues etc, therefore that is exactly what I am doing. More and more people see the thread and it allows me to gauge how many folk have the problem. You okay with that, or can you just go to another thread and ignore this one if it displeases you?

How does that help you? Your D800 obviously has an issue.  Sell it and get over it.

Whining here on DPR for years won't fix anything, and having an agenda and running a campaign against the D800/D800e is just trolling, not to be taken seriously.

Some take it seriously and avoid buying this camera.

Which is a shame.
