Happened to me too. So this gets me fired up. If you have the problem, I'm sorry for you.
Hopefully it will get fixed but don't count on it. Verify. As soon as it gets back check it, and get on their case within 12 hours if its still wrong. And by check I mean check left, center, right, top, bottom. Front or back focus?
Nikon will tell you it is "in spec." Which means nothing. What spec?
And with all respect to the advocates of rigorous testing, ignore that. A camera does not generally require precise external conditions to focus correctly. Have any of us ever felt compelled to verify sharp focus? It's what is inside the camera that needs careful testing.
Is a normal shot in focus or out? Shoot at your friend's eye like a normal portrait.
There is one "test, however, which I found very useful and a low-cost replacement for a fancy lens align system. I got this from one of the Nikon sites.
You need a rectangular thing about the size of a small book, and a nice yard stick. I used a 5 DVD set of a WW2 documentary. It has a lot of big letters and contrasts graphics, for easy focus lock. A Capt'n Crunch box might work better. (taller). The focus target must be square or rectangular.
Put the target on a table, and put your yard stick next to the target like a ski slope. Get the target square with the ruler. Jack up the far end so the ruler intersects about the middle of the target. Example, put the front edge of the target right on the 50 cm mark.
Get the camera about level with the center of the target, and shoot using a wide aperture. You can see if the target is in focus, or by how much it is off.
When it comes back try some normal shots and this easy test. And make them send you a prepaid label if they get it wrong.
Please keep the forum posted. He who has sent his camera to Nikon with me shall be my brother....
