"PDAF wasn’t nearly as accurate as CDAF"
Aug 1, 2012

There are a lot more cool findings, but the first one is what I have said all along.

1. Phase-detection autofocus (even using still targets and center-point only) wasn’t nearly as accurate as contrast detection.

a caveat for Canon...

a few newer lenses did focus as accurately as contrast detection on 5D Mark III cameras but not on 5D Mark II cameras.
