Joshua, let me make my question clearer: we now know that the Sony-Zeiss FE lenses were/are designed by a Sony team, and are badged Zeiss. My question is: was that also the case for the ZA 85, or was it then designed by a Zeiss team? If it was designed by a Sony team like, say the FE 55 or 35, then I expect the Batis to be substantially different from the ZA 85.
