I got the camera in May. I had only 1 week for return/exchange - we don't have any camera shops that have better return policy. Since the issue exhibits itself at large apertures it's not something that you would notice right away, but I started to get occasional issues with focusing on my trip to Europe, which I attributed to my bad skills. Then I got into some health problems while overseas and believe me, camera testing was not high on my list. And then in late August a friend of mine (who also has D800) has sent me Thom Hogan link which I couldn't really do anything with since I didn't have any fast and wide enough lens with me so that had to wait until I got back to Canada - in October. Not that testing it any earlier, while not being in Canada, would be of any use - Nikon has a very limiting service agreements - I have to send the camera for service in Canada.
So, as you see, it's not that I didn't really care about my camera and kept it in a box and now all of a sudden I am asking Nikon for something exceptional. I also do not ask for "premium support" as you put it. I am just asking for this issue to be fixed. I do not even ask for a camera replacement, even though I believe Nikon should just replace all defective cameras. In the end there are warranty obligations which should protect the consumers from manufacturing defects.
Following a legal way of resolving this issue is not a small undertaking - legal fees will be much, much higher than the camera is worth. And this is one of the reasons why all these big companies do what they want - very, very few people will ever attempt to explore the legal route.
While I appreciate your comments I would like to see what would be your attitude and opinion have you had to deal with a situation like this. I would be quite surprised if you were defending Nikon service that made your camera worse after so called service.
