50mm/1.8 AF speed & PDAF
Jan 28, 2013

I've noticed that my 50mm/1.8 seems to have a lot harder time focussing than my Zeiss 24mm. It's very clear that the contrast AF with the 50mm goes back and forth before being able to lock. I know the Zeiss supports PDAF (on my NEX6) so I wonder if this is what makes such a great difference, and also wonder if there's any word from Sony it they will update the FW for the 50mm to support PDAF.
