is it possible to mount an M-mount lens such as Noctilux on a Canon?

thanks,

It can be mounted but will not be practical as it cannot be mounted close enough to the sensor to achieve anything other than close up focusing.

No, if you're looking to inexpensively shoot digitally with M mount the Micro4/3rds standard is your only choice (The Panasonic G1 is the lone m4/3rds body right now).

If you find visoflex m-mount lenses (not noctilux, usually tele's) you can get a visoflex to EOS adapter (search ebay). Some minor deconstruction of the visoflex mount lenses is required but no machining.

The shortest is the 65mm f4 macro-elmar, followed by the 90/4 Elmar, 90/2.8 Elmarit and 90/2 Summicron - only the much older variants though, not the new APO summicron.

I looked at the distances, it is only possible with the rebel / X0D body style with small mirrors (1D's need not apply). This will require the removal of the EOS mount, machining the guts of the camera out, then epoxy / screwing a M mount in. This will not be cheap to do the NRE will be high, and you may need to sacrifice several Rebels before you get it right. I wish you the best of luck trajan in your opto mechanical engineering project.
