Leica Leica M to Canon EF adapter


Dec 17, 2014
anyone know if this is possible????
I'm not looking to put a Leica M lens on a Canon body - but rather - I bought a BlackMagic 4k Cinema camera that has a EF lens mount...

rather than now going after Canon glass - i'd rather mount my far superior M lenses -
they wouldn't autofocus - but that isn't a problem for strict video (in my opinion) anyhow.

i see that there are some adapters on eBay - but it isn't clear to me what EF-M or EF-S etc.
the camera states Canon EF mount... thats all i know...
anyone??? Thanks

The flange distance of the EF mount is 44mm, the M-Mount is ~27.8mm. That;s like using an 16mm extension tube, close-focus only.
