Has anyone done or seen a test done of the 28mm ZM Biogon on a Sony A7 series camera with the thin filter stack modification? I really want to see how this lens performs after the mod because it's pretty bad on an un-mod'd cam. Great on an M 240 though so I know it's ''possible' for it to be good on digital.

I haven't. Suggest you go read Paul Roark's column on conversion over at LuminousLandscape in the B&W forum. He did a thin film conversion and wasn't satisfied. Followed that with a OEM standard conversion for astrophotography to dupe the Tech Pan film he ran out of. Seems to be using Zeiss Loxia lenses. I've a Zeiss Contax CY 28mm f 2.8 that works fine, but prefer Loxia lenses for the EXIF data.
