CANON LEICA-R COMPATIBILITY DATABASE

Specific Leica-R and Leitz-R Lenses Which May Not Fit Canon EOS dSLRs

 

LEICA-R LENSES THAT MAY NOT FIT CANON dSLRs

 

The flange thickness on a Canon / Leica-R adapter is ~3mm. 3mm is two times thicker than a Canon / Contax adapter, so the Canon / Leica combination tends to be more forgiving. Most Leica R lenses fit on a Canon EF or EF-s dSLR camera without any problems (via adapter of course). However, there are exceptions. 

  1. Leica 21-35mm F3.5 ASPH Vario-Elmarit-R

  2. Applies to the Canon 1Ds Family, Canon 1D Family and 5D Family

  3. The Leica 21-35mm ASPH is a simple solution. The plastic shroud at the rear of the lens interferes with the Canon mirror. Three small jewelers screws hold the plastic shroud in place - unscrew them, remove the shroud, put the screws back in place for safe keeping. The entire process takes less than a minute with the proper screw driver and is 100% reversible. The shroud is a cosmetic piece and removing it has no effect on the lens’ operation or performance. I owned the 21-35mm ASPH and it worked with the Canon 1Ds and 1Ds Mark II. The Canon 5D may still have issues in the 21 to 24mm range, so its value is “I” (iffy).


  4. Leica 28-90mm F2.8-4.5 ASPH Vario-Elmarit-R

  5. Applies to the Canon 1Ds Family, Canon 1D Family and 5D Family

  6. The 28-90mm has a similar looking shroud as the 21-35mm; however, there is a small spring held in place by the shroud. Removing the shroud releases the spring which can lead to problems. We have received conflicting reports with one person successfully removing the shroud without losing the spring. Another person said he removed the shroud and the spring popped out and the lens had to go to Leica for repair. Before 2012 the 28-90mm was pretty much a non-starter, but now Leitax offers a conversion kit - see the Leitax site for more info.

  7. Leica 16mm F2.8 Fisheye

  8. Applies to the Canon 1Ds Family, Canon 1D Family and 5D Family

  9. Unfortunately a mirror shave is required if infinity focus is required. However, if willing to use the lens focused at closer distances such as 5 feet, it can be usable. The 16mm fisheye’s rating is “I”; my suggestion is the Contax 16mm Fisheye - it is an excellent lens.

  10. Leica 19mm F2.8 Elmarit-R

  11. Applies to the Canon 1Ds Family, Canon 1D Family and 5D Family

  12. The second version Leica 19mm F2.8 Elmarit-R requires extreme “surgery”. In terms of optical performance, the second version is the one you want - and it costs much more than the original 19mm. The original 19mm is probably a good lens for the 19mm look, but if seeking sharp corners, the second version is a better choice. Some owners modified the 19mm Elmarit’s (second version) rear housing by grinding it down approximately 2mm. Not the entire rear housing has to be ground, just lower half which catches the mirror as the mirror swings up. The earlier 19mm F2.8 Elmarit fits the Canon bodies without modification.

  13. In the case of the Leica 19mm Elmarit - the safe route is buy one which has already been modified. Let somebody else take the risk - and you enjoy the benefit. Also, Zeiss recently released the Zeiss 18mm F3.5 Distagon ZE. The new Zeiss lens costs less than a used Leica 19mm Elmarit-R, so I would buy a new ZE avoid all the hassle. One last possible option is a Nikon dSLR or Sony dSLR with the Leitax adapter kits. For more about Sony dSLRs and Leica lenses, click here, and here for Nikon.

  14. Leica 24mm Elmarit-R

  15. Applies to the Canon 1Ds Family, Canon 1D Family and 5D Family

  16. The Leica 24mm Elmarit-R does not clear the mirror and a lens modification is not possible. If you are willing to shave the mirror on your 1Ds or 5D, then maybe. Some options include the Canon 7D or other Canon EF-s dSLR. The EF-s bodies have smaller mirrors, so there are no clearance problems. An alternative to the 24mm Elmarit-R is the 28mm F2.8 Elmarit-R which receives very favorable reviews.

  17. Leica 28mm F2.8 Elmarit R - Model 11259 and Model 11333

  18. Applies to the Canon 5D Family

  19. These two lenses are marked “I” (iffy) because of conflicting reports with the Canon 5D Mark II. Optically the lenses are identical, model #11333 is simply the ROM version. There have been mixed results with #11333 on the Canon 5D (and Mark II), so it was already coded as “I”. Subsequently, another person reported their 28mm Elmarit (#11259) fit fine on the Canon 5D Mark II. Even though he had success, I still coded the lens as an “I” because it is the same mount, etc. as model 11333. So, the 28mm Elmarit may work on a Canon 5D / 5D Mark II; however, some people may encounter clearance issues due to adapter thickness and/or production variances the mirror box.

  20. Leica 35mm Summilux

  21. Applies to the Canon 1Ds Family, Canon 1D Family and 5D Family

  22. The 35mm Summilux-R will not clear the mirror on Canon full-frame bodies. If you are willing to shave the mirror on your 1Ds or 5D, then maybe. If you would like to learn more, again, try www.fredmiranda.com “Alternative Digital Systems & Lenses” forum. Some options include the Canon 7D or other Canon EF-s dSLR. The EF-s bodies have smaller mirrors, so there are no clearance problems. If willing to look outside the Canon EF mount, there is hope with a Leitax adapter kit for the Sony A900 / A850. The 35mm Summilux with the A900 is noted on the Leitax pages, contact David for clarification.
