Fotasy Leica M LM Mount Lens to Canon EOS M EF-M Mirrorless Camera Adapter, fits Canon M1, M2, M3, M5, M6, M10 Mirrorless Camera

Does not properly mount M mount lenses. Significantly too tight on the Leica M side and does not allow for enough of a rotation to engage the locking mechanism. Do not buy.

This works as advertised. Be aware that you have to manually focus and set the aperture. I had trouble getting my EOS-M camera shutter to fire because the adapter makes the camera think that there isn't a lens attached. You need to change the following camera setting: Custom function menu: C.Fn-7 Release shutter without lens: on

It fits the body well but doesn't fit the lens at all. As you can see in the photo, it's pretty off-center because it's so tight that it doesn't even turn. Rather than adding more force to turn it, I'm returning it. It feels sturdy and it could be great if only quality control was done properly.

the adapter works well with all Leica M lenses.

Very affordable and works perfectly. Great to be able to use my Leica M mounts on my Canon M mount ; )
