Unfortunately the regular Sony full frame 50mm F2.8 macro's autofocus is too slow for my needs, and so I am still on the hunt for a 50mm macro that suits an A7RVI. Has anyone tried a Zeiss Touit 50mm macro on a full frame sensor? If so what is the coverage like on the FF sensor?

If so what is the coverage like on the FF sensor?

It will be the center 50%. To see what that would be take a picture at 50mm then one at 35mm in APS-C mode.
