Leica M to Canon EF mount adapter?

Anybody have experience with a Leica M to Canon EF lens mount adapter? Recommendations? Thanks

I believe it only works with the Leica VisoFlex ( http://elshaw.tripod.com/Visoflex/Visoflex.html ) lens elements, because the distance from film plane to rear element is so different from Canon and Leica M standard lenses.

Please, if I’m wrong about this, correct me. I really hope I am and there’s a way to use my standard M lenses on my Canon cameras.

It’s not possible due to the fact that Leica M lenses are designed with a shorter mount-to-film (or sensor) distance. Rangefinders don’t need mirrors, so the lens can be mounted closer to the film.

Leica M Lenses can be used on the micro 4/3 cameras and the Sony NEX system since they have shorter mount distances.

You could adapt Leica R lenses to Canon I think, or check out the Zeiss primes which are quite good.

I’ve seen a leica r mounted on a canon. I’ve also used an M-mount voigtlander on my Panasonic GF-1

Maybe it is a useful link:

You could do it by using
1) a Leica M to 39mm screw mount adapter (Leica and Voigtlander make ’em)
2) a Canon FD to 39mm screw mount adapter (Canon used to make ’em)
3) a Canon EF to FD adapter (someone, maybe Canon, used to make ’em)

then you could put your Canon EF lens on to a Leica M body.

Not possible the other way around because a Leica M body is thinner (lens flange to film plane) than a Canon EOS body.

do note that Canon EOS is one of the thinner SLRs, so you can put almost any other SLR lens onto Canon, including Nikon, Contax/Yashica, M42 screw mount, Canon FL/FD, and many others as well.

Of course Leica M as noted above is even thinner due to it being a rangefinder, so you can adapt most SLR lenses onto Leica M (as you now can for Micro 4/3 also), for Leica M this is most useful for expensive superwides, like 17mm or 18mm or 20mm lenses that don’t require much focusing.

“1) a Leica M to 39mm screw mount adapter (Leica and Voigtlander make ’em)”

No. There is a 39mm-to-M adapter, but not the other way around. If you look on CameraQuest’s page (The US distributor for Voigtländer) they have this to say:


“The bottom line is screw mount lenses are more versatile than M mount lenses because screw mount lenses are useable on more camera bodies — both Leica screw mount bodies and Leica M mount bodies. M mount lenses will only mount on M mount cameras.”

“There is a 39mm-to-M adapter, but not the other way around”

That statement is ridiculous.

No, James, it isn’t ridiculous.

Can you find me one for sale somewhere?
To mount an M lens on a 39mm screw mount body?
It simply isn’t possible to use an M lens on a 39mm LTM body, unless you were to take the lens to a machinist and have the thing irreversibly modified.

James actually means the 39mm to M adapter. Look at what he writes, the question is how to get an EF lens onto a Leica M?

And the answer for his logic is correct: EF —> FD —> M39 —> M

Except that it is wrong for EF —> FD, THIS is the one that’s not possible while maintaining infinity.

Flange distances:

EF = 44mm
FD = 42mm

You can mount FD on EF but not vice versa.

But, because of the lack of an aperture ring on EF lenses, it’s not that practical to mount them on Leicas. See following article:


DO note that the adapters for non-infinity combinations exist, for Macro work. Your Leica lens becomes an amazing close-up lens on your Canon EOS SLR. This actually answers Edward’s original question.

Have I gotten this backwards?

I’ve read it a couple of times now and it still seems like the original question was how to mount a Leica M lens onto a Canon EOS body, not the opposite.

Other than the adapter that will let you use a handful of Leica Visoflex lenses, there is no way to use M lenses on an EOS body. I have a handful of Leica lenses that I’d love to use on my EOS bodies, but I still believe it just isn’t possible.

I’ve never had the desire to use my EOS lenses on my M bodies, so I have no idea if the reverse is possible.
