Hmm...the AF test vids don't appear to test the PDAF hybrid scenario...

Clearly, Canon's CDAF implementation performs slower than its mirrorless peers.

I was curious about Canon's hybrid pdaf/cdaf implementation. But the existing demo doesn't appear to test it. The focusing targets appear to be placed outside of the PDAF area in these views.

The PDAF area being the area noted in green:

Too bad, I was curious, though, if its implementation of PDAF as a "direction chooser" had any demonstrable benefits. These tests are more like a test of its CDAF capabilities by itself.

Perhaps a later set of tests on the EOS-M.
