Voigtlander 28mm f/2.8 Color-Skopar Review
I can take a lens that exhibits the so-called Italian Flag Effect on an M and put the same lens with a thin adapter on a Sony or Nikon and eliminate the effect... YMMV
Edit: To elaborate somewhat, one problem with edge color cast is lens registration distance. As with trying to use FSU LTM lenses on an M body (film or digital), registration distance can affect output. In the case of FSU lenses one can add or remove shims as desired, or alter the registration distance of the lens via an adapter. The profile of the lens field curvature also comes into play, depending on the point-of-focus and aperture combination. And then there is a particular sensor's well and micro lens array and cover glass thickness question... If you'd like an optical engineer's perspective on some of the issues I'd suggest checking out some of Sonar Brian's threads on RFF...
