Re: HAve you FTuned lenses

No, I didn't check the finetuning as the lens seemed to focus fine before, but I surely will check.

FT or MA will correct only very minor front or backfocusing. In the case of the D600 it's probably backfocusing slightly, something you can only see if you comapre to a correctly focused image. To test it, it's simple, just  use LV contrast AF, which usually gives very accurate AF, and regular AF on the same subject, MLU and tripod (and shutter delay or remote, to avoid camera shake).

BTW, did you use MLU and tripod on these?
