Have you had any experience with any of the following other than the 80mm? I am interested in sharpness across the frame at the widest aperture possible (not necessarily looking for sharpness wide open unless.). Steel Chen gave me his opinion on three lenses he thought were sharp wide open. I posted the following list on the Adapted Lens forum and got no response. I am using some Pentax 645 lenses but would like to explore other brands. I'd like to extend my lens lineup via adapted lenses. Steel Chen is developing a Contax 645 AF adapter for the GFX 50s. I can't address your question but I have one for you if you don't mind. Guessing I am missing something fundamental beyond the sensor resolution. The question is: with the D850 (46MP) being released soon, what are thoughts on Image Quality between this lens on D850 (46MP 35mm Full Frame) vs same resolution on MF digi back? I did shoot with a Aptus 75 at one point and it was 6666*4992 = 35MP. I miss the medium format magic though, and am considering buying a Contax body again just to shoot this again in its full glory. I have since sold the Contax body and have used the lens on my (aging) DSLR (12 MP). I LOVE the 80mm and was reason I got into the Contax system to begin with. I have a Contax 80mm f/2 lens which I have used on both a Contax 645 as well as my Nikon D700 (via a Nikon F mount "JAS" autofocus adapter from steel chen).
