I just got the Nikon 35mm 1.8 G FX lens the other day from B+H and I detected that it is front focusing. I tested the lens on 2 D750 cameras and the results were the same. I have to push the AF Fine-Tune to its maximum of 20 to get it close to spec but that is still not enough. Curious to know if anyone has experience with this lens and if I just got a "bad" one. I plan on sending it back.
