In AF.C, the camera tries to track the eye. On AF.S and AF.A, the focus is locked and does not track. My test target isn't the best, but it does seem to work as expected. As I said, it's very lighting-dependent, and point selection needs to be on Auto for this to work.

Face detection is an undocumented feature, but I can confirm it exists on my K-3 II.
