I'm considering adding a 135mm to my a7R kit. Either the Sony/Zeiss 135mm f1.8 or the Zeiss 135mm 2.0 ZE.
Anyone used both? Any significant performance differences or gotchas? (I know the Sony is autofocus, but that's not critical for me.)
I'd use the Sony on the Sony LA-EA4 and the Zeiss on the Metabones SA3.
