It is leaking lubricant or oil on the 2nd replacement body.... see update below!1st I did was to test the left focus to see if I have the problem as some people reported.

if shooting a flat surface (it's totally my guess here).I wonder how many people with D3 and D700 test this AF problem, or Canon guys

The D4 is for the few who require extra speed and don't want high density sensors; the D800 will undoubtedly leave most people feeling elated.

I am aware that some people got lucky that some Nikon service centers were able to fix those problems, but I also notice that there are many reports saying their camera came back without fixing or being worse

As an off topic point, people trash D800 when comparing high iso noise with 5D mark III.

16 megapixels will give you a wonderfully sharp 8x10, and most people would have no problem with larger blowups to even 16x24 with some careful processing

If you do not know how to take a photo with this camera without being on a tripod, then this carema is too much for you or you work or is a fan of canon who is trying to deter people from buying this camera

It is simply ridiculous how this issue escaped any QA, as more and more people are reporting issues

I know that many people will turn around and bash this review which is fine as everyone has their own opinions but all I am saying is conduct a few scientific tests by trying out different lenses under different circumstances such as lighting, location, subject etc and then draw the conclusion

There are major problems and Nikon KNOWS and is jerking people around.

I'd like to thank those people who gave this one and two stars.

Center/right sensors requires no AF FT.At 70mm F2.8:(which most people are less concerned of)Left/center/right all shows optimal focus results without AF FT.Strictly speaking, the D800 I have do have minor left AF issue,In my opinion, it's totally tolerable, if it just require -1 to be sharp

Many people reported improved AF speed and accuracy.

You can not cheat when it comes to photography, people will claim DSLR's are a dying breed but these people never learned how to operate a "real" camera.

Some people have complained about the slow frame rate of the D800 and that is a consideration if you are a sports/action shooter

It makes me wonder how many people have the same issue with their D800 bodies but don't even notice the clear lack of sharpness of their images.
