Quote:Reall tests show that select DSLRs (Canon's 70D for instance) can focus more accurately with PD AF than mirrorless with CD AF.  It does depend on the lens used (some lenses with PD AF are just inherently "crude").

The funny thing: many mirrorless cameras replaced a mirror slap with a more problematic shutter slap. The irony!

 

And yes, I do not like EVFs. With very good reason.
 

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.
