The Great Ridge, Mam Tor - Nikon D800 and a Nikon 16-35mm F4 and Lee 0.9ND I will have to make sure that all my footballers are running from right to left! The only instance that I find it problematic is if I am shooting fast moving action that I want to be in the LHS of the frame. It doesn't impact on most of my photography and actually can be avoided most of the time. I have decided to work around the problem until Nikon has admitted the issue and rolled out a permanent fix. Nikon NPS UK were brilliant and 1 week later I got it back and the problem has been improved but not solved but does seem to be exaggerated on the Sigma 50mm F1.4 lens.

My focus tests were performed on a Sigma F1.4 50mm lens (This exhibited the strongest focus problem) After some ad-hoch tests (see below) I emailed Nikon NPS in the UK and they asked me to send it in. I had read about this online and didn't think my camera had the same problem. It all started after I had shot some portraits of my kids and noticed that when using the edge focus points they weren't as pin sharp as the central point. I have owned my D800 for 2 months, 1 week of which Nikon had it.
