I'm just trying to gauge interest in an adapter that would adapt leica m-mount lenses to the eos-m system.
It would be similar to my Sony NEX version in that it would read 6-bit coding (if the lens has it) and report the focal length and maximum aperture, but I'm not sure about the details yet with regards to focus coupling or peripheral illumination correction (The sony version will auto invoke the manual focus zoom when focus changes. I'm sure something similar can be accomplished with Magic Lantern).
Keep in mind this would take a while to develop. And as I said, I'm still gauging interest to see if it's worth while to develop.
