So, if the mirrorless AF system matches SLT AF performance, AND with elimination of mirror, improves high ISO performance, what exactly is it that you believe would be a step back?

Where are you getting that mirrorless AF system will match SLT AF performance?

SLR to SLT transition was that (which you deflected with the excuse on high ISO noise). I expect a similar SLT to mirror-less transition on A-mount. The question is, why would you prefer to assume otherwise?

We won't know until products are actually out and tested, but according to the source cited in the first post -- Mirrorless AF system will NOT match SLT AF performance.

Then refrain from drawing conclusions, like you just did (again).

So far, the best OSPDAF still doesn't quite match dedicated PDAF. Not in the Nikon 1 cameras, not in the Canon 70D. And according to the rumors, not in the Sony A7.

So? And there is no reason to believe that Sony will stick with the OSPDAF system you speak of, to replace the mirror.
