I had brought the D800 in one of the major electronics markets on Saturday (19-1-2013). SN 6,049,627th I had tested the camera in business precisely to the AF problems. Single-AF, center, right, left, the. In lines of text that were slightly slanted Everything was perfect. Unfortunately, I had not realized that the camera's "DX-box" was set, that is, only the center of the viewfinder image (or the sensor) was exposed. At home, I came across the not imposable gridlines that DX and FX was not adjusted. After switching to FX (all visible in the viewfinder, large field is exposed) could be observed at once that the camera left was unable to focus (back focus, that is, not the targeted line of a book at the left set Single Servo AF was sharp, but two or three rows behind). The Single AF in the center and right were ok. The electronics market was 100% accurate, an employee checked with the 50mm 1.4 the problem, the camera goes back to those of Nikon and the purchase price was paid. They also offered me to let them repair at Nikon, but who knows whether it is because then all ... In my opinion, only fully functional devices should come on the market and it would be up to Nikon, which should be checked before delivery. The problem has been known for more than nine months. Tip: Before buying on FX, take very good lens, photograph slanted book lines. Or in shipping make at home. Otherwise: Super-resolution. A kind of microscope photography. Light greenish appearance of colors on the display (but not the images themselves that are ok!). But it can get used to.
