What about the Zeiss Touit line? I know you'd have to switch the camera to APS-C mode, but at least you'd have autofocus, right? The Zeiss Loxia are full manual (focus and aperture)... so they don't seem to have any real advantage over a Zeiss ZF lens for the A7S, other than a declickable aperture. However, is the focus scale more calibrated and thus more reliable over a Zeiss ZF lens? At least with the ZF, you can use them on any cam with the right adaptor.
