I really like this camera and it seems to work great with all my lenses except one, my 80-200 2.8 af-d. With this lens I am getting significant backfocus. Even with the lens fine tune set to -20 it is still backfocusing about 2cm and I cannot get anything at small f number in sharp focus.

If I use this lens on my D5100 and manual focus (using focus indicator dot) I can get nice sharp pictures.

The fine tune corrections on my other lenses are

18-55 DX VR : +1

35 1.8 DX : 0

12-24 DX : -8

There is no obvious systematic back focus in general, just a really terrible one with the 80-200. Any ideas on how to go about fixing this? Could it be the lens and not the camera?

Thanks!

Doesn't seem to be an "issue" with your camera but rather your lens/camera combination.  How do you really determine +1 on the 18-55 dx?
