I have had my D800 for a week tomorrow. I got it from B&H and am using the Nikkor 24-120/4 VR lens with it. I now have taken around 600 images and the focus is fine. If there was a problem, and from what some of you have said there was a problem, it is now corrected (at least on mine). I'm really enjoying my D800. Cheers, Bill P.
