Typically, if you try to mount some odd ball device on a consumer EOS you lock up the camera and get a low battery error which you clear by taking the battery out for long enough that the capacitors lose their charge.

The mechanical connections abandoned with the FD lenses were replaced by electronic ones in the EOS lenses - focal length, aperture and other data. What does that have to do with imaging and uneven exposure? Software workarounds for lenses? Then why would one Leica lens exhibit such a problem and not all of them, since there's no "mechanical" connection with any of them? Do these workarounds you're talking about deal with fall-off, compensating for lenses based on the response of sensors to light in a given area (which varies with each lens). I would think the 35 Summilux R would probably show such fall-off when used wide open in bright light. Anyone try that one?
