D7000 AF Tune and Back Focus

[Sar NOP]

+2 adjustment is pretty small, I would suggest doing a consistent test (tripod, chart etc), this was the only way I worked out what adjustment to put in - otherwise there is too many variables when in the field to deal with.

For me, AF fine tune is a useless feature because indeed "there is too many variables when in the field to deal with".

I think useless is a bit harsh, at teh end of teh day if you have a lens that when on single point focus aimed at the eye of a portait and misses focus and you can't do nothing about it then thats useless, at least with the limited AF tune function you can 'correct' some back focusing issues.
