"the Phase Detect PDAF system of the NEX-5R reduces the true resolution of the central focus zone by 20%"

which is a bit of a misquote, the article said "could reduce" and "by up to 20%" which means it could be anywhere between zero and twenty percent. no one (outside of Sony) knows.

sorry, my inner pedant just kicked in.
