How Much Faster Does Hybrid AF Have to Get to Be as Fast as Phase Detect?
Jan 25, 2013

I am anxiously waiting for hybrid AF (i.e. on-sensor PD/CD AF) to be able to replace separate sensor Phase Detect so we can finally be able to go into live-view and be confident that we will get fast af along with the already very accurate af of PD/CD AF.  It is clear that manufacturers are going that way (mirrorless u43rds with CD-though PD/CD may be available on the Olympus E-7, Sony has started PD/CD on-sensor in the NEX 6R and Canon has started it with EOS-M and the T4i).

So, the question is, how much faster does on-sensor PD/CD have to get to equal separate sensor PD?
