Focus fine tune D600+50mm f1.4
I was having a play with the AF fine tune on my D600 and as I thought my 50mm was a tad soft-noticed a big improvement when I set the AF fine tuning to -20. Similar result with my 85mm F1.4.
Is this sort of thing common? I'm wondering if it is a lens or body issue- will have to test more lenses to see if it is common across the range (although my 180 2.8 seems ok at 0).
