Re: How to adjust viewfinder back focusing on D810?
If it\'s a ZF.2 100mm/2 MP you can set an AF fine tune value for the lens (try negative values for focus occurring behind the intended target). If it\'s a ZF it can\'t be AF tuned, because the process needs a CPU lens.
A caveat: if you have more than one ZF.2 lens, Nikon\'s systems treat them all as the same lens. So if -10 worked for your MP, but you had a 25mm/2 Distagon too, the camera would apply -10 to it also. This seems to be mostly a theoretical problem. I have not found this to be an issue with any of my ZF.2 lenses (25mm/2, 28mm/2, 35mm/2, 50mm/2, 100mm/2 and 135mm/2) and my D800E. All of them work best at Zero AF fine tune setting. Zeiss seems to have better QC than Nikon on the flange focus-dimension, because my AF Nikkors are all different and only one works well at Zero.
