I think that all this shows is that on-sensor PDAF is probably the way the mirrorless cameras are going to take over from DSLRs for C-AF. I hope that the next generation E-M1 has Liveview at higher fps rates, the option to choose between PDAF and hybrid AF and cross type PDAF focus points.

I thing that PDAF is just a phase and in future we use more software based focusing with CDAF as it is promising once we get global shutters and we get away from the shutter etc.

It is just question of the time when we get better algorithms and processing power to do it well.

The big advantage of on sensor PDAF is that it enables DSLR lenses to be used on mirrorless cameras with no focusing speed penalty - that of course if why the E-M1 exists.

That is surely a big factor for Canon/Nikon/Pentax and the timing of any decision to move from DSLRs to mirrorless.

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.

If I were to make a direct comparison, I would say CAF use and performance is not dissimilar to the original Canon 5D taken all round, though there are situations where it is significantly better.
