Over the last few months I've been noticing an annoying back - focus problem on my
Nikon D7000, regardless if I was using a AF-S or AF lens. But the problem seems to happen more often on my
35mm 1.8G and on my
Recently I've found that I could fine tune the focus to try to solve this problem, and I've even used a test chart for sharpness and made tons of tests on an one meter distance from my object. After I've analyzed the results I've set my 35mm to
-20 and my 50mm to
-5 on the AF Fine Tune menu.
It worked just fine on my chart, but when I took my camera to test with "real world applications", once again I had tons of pictures with back-focus...
I've found this post which that guy seems to be having the same problem as I am. But my question here is:
- Can this problem be solved solely by tuning the auto focus? If so, which are the optimal values for my lenses?
- Can this be caused by something else on the camera?
P.S.: This is unlikely to be a lens problem, as I've tested the 35mm on a D3100 and my 50mm is brand new... And the problem also happened with a borrowed 50mm 1.8 D.
