Re: D800 Focus Problem Continues -- Your Insight Requested

Thank you Mack and the others who are trying to help.

I apologize for any offence caused by my frustration.  I do not agree that special testing is required.  Except for Nikon.  Their testing is definitely screwed up.

i have new information. I tried focus fine tuning each of my lenses.  Every single one of them is in severe front focus,  except the 105 2.8, which is a puzzle.  The tested lenses are 24-70, 85 1.4, 50 1.4, 14-24, 105 2.8.

Each of them maxed out at +20 without the focus point reaching the target.  The 105 exception is at +11.  Maybe it would be back- focusing on another camera.  That's my hypothesis anyway.  I suspect all of my lenses are fine on anybody else's camera,  except perhaps the 105.  Which is still pretty good.

i just recalled my center  and left were ok before the "repair" number two.

Any way, after attempted fine tuning, I tried "normal" photos with each lens with fine tune on and then off.  Thumb wheeling between the two images is a night and day difference.  Like glasses on vs. glasses off.
