It is true from my experience that Olympus cameras stumble occasionally in AF, even for S-AF, which I use exclusively. It's a CDAF system and I think some high contrast area of the frame gets detected first and gets the AF's attention or priority, e.g. the edge of the head or ears in a back lit portrait because that part is lit up while the face is darker and have less contrast. My theory.

Yes it's exactly how you write it.

I think it has something to do with a focusing speed. Or well better say Olympus tries to stay in a camp of very fast focusing cameras. So theyr priority is speed over accuracy (that's just how I see it).

I always only use 1 single focus point. And for example for a headshot picture small AF point is even smaller than an eye. So it should nevet ever focus onto ears or back of the head. But it does.

Sadly I have deleted all these missfocused shots since I always delete all that garbage just after my shoting session. Hmm.
