PD-AF can't overcome focus shift. That alone makes it an inferior concept.

Shutter slap is as present on DSLRs as on mirrorless cameras - take the Nikon D3x or Sony A900 as examples.

The difference is ... modern mirrorless cameras have a full electronic shutter with zero camera-induced vibrations whereas DSLRs remain compromised by the mirror slap till the dawn of their era.

 

I like EVFs for very good reasons. 

Not even that is true. CD AF cameras don't close down the aperture either when focussing, so focus shifts still can occur.

No Canon DSLR has a similar shutter slap issue. 

The full electronic shutter often comes with rolling shutter effect. That is why they still offer mechanical shutters.

 

Yeah and I like OVFs for very good reasons also.
