I thought my lenses on the D7100 were front focusing a bit so I did a test. One with my 50mm 1.8 and one with my 17-55 2.8 and it looks like it is front focusing on both lenses. Wanted to get a few more eyes on it before I messed with anything. Also, does it matter if the lighting is even when doing this test?

Assuming you focused on the red 0, looks like it's front focusing on the front 4. Just dial in some lens calibration correction (or whatever it's on called on the 7100) and try again. Doesn't cost anything but a little time.

The lighting looked fine to me on those targets.
