I think I am a victim of face detection on my D800 - but may be I am doing something wrong?
I took a few pictures with my D800 + Sigma 35 1.4 Art wide open. The pictures had two faces in them but in a different focus plane. It seems like the camera was trying to get both faces in focus - impossible in this situation.
My settings for AF: AF-ON only - AF-C - Single AF point.
What am I or the camera doing wrong? Is face detect always on? Or can it be turned off?
