if the subject is a plane and the capture is a cylinder or sphere you wont be able to achieve subject in critical focus. The only way would be to stop way down which be okay if that is what you want but it would never allow for selective focus technique.
All lenses are essentially flat field, even the ones not marketed as flat field are curved field but the degree of curvature is slight and no where near the degree of curvature of that would occur with pan shooting.

For the life of me, I can't see what the problem with this is. A lot of lenses have a curved plane of focus and they seem to work just fine. William Robb
