i transplanted my g28 to a rokkor 55/1.7 helicoid a while ago because i much prefer having a real focus ring to on adapter focusing. this allows me to use the fairly well designed rokkor infinity stop adjustment as well.
How can the field curvature , a property of the lens, be different on cameras/sensors?
The corner smearing can differ on sensors oc.....
I'm not good on theory, I'm more practical - for me it's enough to understand behavior of optical system in practice so that I can utilize it to fullest potential when I'm using it, and less important to know why things happen in theory.
Toothwalker/The Suede most likely know if there is theory behind this.
PS. "a property of the lens" - would be careful with this, as far as I see it, it's "a property of optical system". On the film days there wasn't anything else than lens, but in current optical systems the sensor cover glass/AA-filter will be part of the system, and results are not purely from the lens.
Here are some images that I took last evening, April 10, 2014 in Magic Hour and as the sun was setting for some harvested and cut corn fields in Lower Macungie Twp, PA. All images taken with my tripod mounted A7r and my Leica R 35mm-70mm f4 Vario Elmar Zoom lens and processed in LR5.4.
Some more shots with the FE 35...it's really a nice lens! Incredibly sharp, small, and has that Zeiss look. Not quite the character of my CY 35-70 @ 35, but I'm still impressed!

EXIF matches the texts on photo frames, so I doubt mismarking issue. EXIF of course could be copied or edited almost freely. Also pictures are clearly worse than Bob's usual work (halos on contrast edges, lack of texture etc.) so I would assume these are from some small sensor camera, because f/22 on fullframe doesn't do as bad damage as the one we can see on these photos.
