[QUOTE="dieselnutjob, post: 827393, member: 47318"] I just bought a 105mm DC F/2 AF-D lens on ebay. On my nikon Df I have to max the AF fine tuning all the way to +20 to get it to focus properly whilst on my D780 it's about +15. Is this a fault of the lens? As it's a purely mechanical focusing system I don't see how the lens can have much to do with it. I would love to understand how this really works. [/QUOTE]
