The problem is that as of now, PDAF has neither the coverage or sensitivity of higher end DSLRs, so essentially while there is nothing wrong with PDAF in the right conditions, it's simply not as capable overall.

Do you know whether there is any fundamental reason why on sensor PDAF is always going to be inferior to the sort of PDAF system in a DSLR using a separate mirror assembly and PDAF array?  (Maybe that is one for the Science and Technology forum).

Canon has its dual pixel sensor that first arrived in the 70D and is also in the 7D MkII and that certainly gives PDAF coverage of the whole sensor.  However, as it is currently implemented, it doesn't seem to have as fast AF in Liveview as a top mirrorless camera.  I wonder why that is.  I also wonder why Canon hasn't put it in the EOS-M.
