It is well-known that the Zeiss 2/28 has substantial field curvature, which can be used with interesting effect on full-35mm-format cameras, but is obviously not everyone's cup of tea. Well, I was wondering about using this lens on APS-C and APS-H Canon cameras. The field curvature may be in the "wrong" place for cropped-frame sensors, as it is, reportedly, with the Canon EF 20mm f/2.8 lens on APS-C, for example.
This question is prompted by the local availability of a pre-owned Zeiss 2/28 ZE lens. ("2/28" is Zeiss-speak for f/2 28mm.)
Thanks, in advance, for taking the time to read this, and reply.
