Totally agree with the previous post, but it's worth mentioning why PDAF (Phase Detect Auto Focus) is so much more useful than CDAF (Contrast Detect Auto Focus).  The PDAF sensors, detect not only that the focus is wrong, but by roughly how much, and in which direction.  CDAF may be more accurate, but it requires the lens to hunt (sometimes going in the wrong direction) before it gets a focus lock.
