Well i actually really don't bother with how people want to shoot their pictures, just curios what's so great about it and some people must just swear by it even if they end up wit a oof shot. I know the af technology is there just to assist and for further fine focusing, mf is the way to go. Anyway i am one of those people who will still pp my pic after a shoot. So with af, when focusing at the eye, if i'm not happy with the sharpness after pixel peeping, for me there is always a proper usage of unsharp mask. I know some do not "cheat" as shot die die produced by camera must be accurate, but hey its up to one's personal preference.
