Leica-R and Leitz-R Lenses that Work on Canon EOS dSLRs



PebblePlace Copyright


The Leica-R / Canon database is a quick reference to see which Leica-R lenses can be mounted on Canon dSLRs via third party adapters. Most lenses work without issue; however, some lenses extend too far into the chamber and the Canon mirror will not clear the rear element or some other portion of the lens assembly. Most people will only need the FF, 5D, 1.3x and 1.6 columns. Scrolling to the right provides more information about the lenses. Be sure to check out:

  1. Comments - A quick FAQ.

  2. Specific Lenses - Additional notes for some of the more stubborn lenses.

  3. Adapters - General information on Leica / EOS adapters, including HappyPageHK and Leitax.

  4. Links - Other websites which may be helpful in your Leica-R research.


  1. FF refers to Canon’s professional full-frame dSLRs such as the Canon 1Ds, 1Ds Mark II, 1Ds Mark III and 1Dx.

  2. 5D refers to the Canon 5D, Mark II, Mark III and Canon 6D. The Canon 5D / 6D series have their own column because the 5D’s mirror clearance is different than the Canon 1-Series.

  3. 1.3x refers to the Canon APS-H bodies with a 1.25x or 1.3x crop factor. This includes the Canon 1D family which consists of the 1D, 1D Mark II, 1D Mark IIn, 1D Mark III and 1D Mark VI.

  4. 1.6x refers to the APS-C bodies, including the EF mount dSLRs (D30, D60 and 10D) and EF-S bodies (20D, 20Da, 30D, 40D, 50D, 70D, 7D, 300D, 350D / XT, 400D / XTi, 450D / XSi, 500D / T1i and 550D / T2i).


  1. Y means “YES”. “Yes” means the Leica or Leitz lens will work on the respective Canon dSLR and most people have not experienced any problems.

  2. N means “NO”. In some case the lens or camera can be modified to accommodate some of the marginal lenses. For lens-camera combinations marked “N”, there is not a realistic solution.

  3. I means “Iffy”. A lens earns an “Iffy” rating if some people say a given lens and Canon combination work while other people say the combination did not work. Since there is no clear answer, “Iffy” was added.

  4. M means “Mirror Shave”. In other words the lens in question will work if the Canon mirror is shaved. Shaving the Canon mirror is a radical step. If you are willing to assume the risks and want to learn more, see the Comments page.

  5. S means “Shroud”. Some Leica lens have a protective shroud covering portions of the rear mount. The lens in question will fit if the rear plastic shroud is removed. More information about lens with shrouds is available on the Comments page and the Specific Lenses page.

  6. R means “O-Ring”. Currently this only refers to the Leica 50mm F1.4 Summilux-R (E60). There is rubber ring protecting the rear element - similar to a rubber band. It is very easy to remove and re-install.

  7. ? means no data available.


There may be errors in the table. We try to make sure everything is correct; however, there are no guarantees. Be safe and do your own homework too. If you decide to mount a non-Canon lens to a Canon camera, you are doing so at your own risk. Exercise common sense - if something feels wrong --- stop and examine the adapter, the lens, etc. Using an Canon EOS / Leica-R adapter is usually trouble-free; however, there are exceptions. Until you know for sure a given lens and adapter combination works correctly with your camera, go slow and pay close attention.
