I hope the quad AF does not mean quad Bayer as well.
*EDIT* - This post is about claiming 16 Quad Bayer pixels vs the normal 4 Bayer pixels. It is *not*
about QP vs DP design.
I still don't see what benefit a Quad Pixel AF "Quad-Bayer"
(16 Bayer pixels) could offer. For pixels in focus (where you would want extra resolution), phase detect DP or QP gives the same dual or quad values for all values (by design) so there's no benefit there. With out of focus pixels (where the QP values differ) , who cares about increasing resolution as it's just a smear which could be done in post.
So I only see "QP AF, Quad-Baye
r" as marketing BS overclaiming of resolution which I hope Canon has the integrity to avoid.
Also, to be clear, I see QP AF (by itself)
as a brilliant AF method and the #1 new feature which I *really* want to have in my next camera! I have fully given over AF (with my use of "spot focus" and "eye focus" back buttons) to the camera and QP would be a massive improvement over the already brilliant DP design in the R5.
