IS NOT compatible with Leica branded L-mount cameras!
It does not work with Leica’s own L-mount cameras. Yes, we know that’s not what was originally said and many sites still list. Yes, we know it’s super-shady; that’s why we are telling you in every section of our product page. No, it really really won’t work. Putting this adapter on any Leica L-mount camera causes a warning message to pop-up that cannot be bypassed.
MC-21 Adapter-compatible lenses can be found in the recommended section on the left-hand side of this page. Sigma specifically doesn’t recommend use of this adapter with Canon brand lenses, only Sigma brand lenses in EF mount. Use of Canon lenses may result in performance issues. If you aren’t sure whether a lens is compatible, please contact us.
