Originally posted by AndrewG NY It's my understanding that many cameras use both -- features like face detection require CDAF, but use PDAF for speed, particular for continuous AF. Perhaps the hybrid approach you're thinking of is PDAF for the initial large adjustment followed by PDAF for final micro-adjust of focus.
Yes, that is exactly what I'm calling the method of the future: PDAF - CDAF - PDAF. No more front / back focus. I'm always amazed when someone will display pictures asking for help with focus, and the problem is obviously DOF, but someone just has to jump in first with front / back focus suggestions.
