I don't disagree with you on the other elements that contribute to speed of focus; I was touching on what I thought were the main determinants.

Question: some folks in this thread have mentioned on-sensor PDAF. Based on what I understand as the way the light is split for PDAF I don't understand how one can use the image sensor without having the PDAF lens elements interfere with the image. I really thought PDAF required a separate set of micro lenses and sensors. Am I wrong?

Why don't you go to Sony Alpha Rumors, and check out the post which mentioned the on-sensor PDAF. You do know new stuff gets invented all the time, don't you?
