Quote:The Problem with sensor PDAF is primarily at low light (or high ISO noise if you wish).
And SLT loses 1/2 stop of light anyway. Plus we don't know what kind of on sensor AF is coming in future. All we know for sure is that A-mount is not going anywhere, as Sony is still releasing A-mount lenses, including Zeiss 50mm next month.
