M mount lenses compatibility list

Additional comment regarding the SLR lenses I tested via adapter:

Canon EF Mount - all lenses should be no problem, however work only with open diaphragm.
Minolta MC/MD Mount - all lenses should be no problem.

Thanks,

Oleg

Oleg, which EF adaptor are you using? Have a Zeiss 50mm MP that I use on my 5DII and debating whether I should pick up a M mount dedicated 50 or not.

bought one on ebay, Canon EF-Leica M adapter
 
Do you guys know if the Russar 20/5.6 would fit in the module?

HI, I have a 90mm Summicron f/2, but it doesn't seem to mate to the A12. It seats, but won't rotate. It was made in Canada. Any thoughts? Thanks, Al

Hello everybody,

yesterday I bought a Leica-M Summarit 2,5/75mm. It works fine with the GXR with M-Mount.
You can add it to your compatible lens list.
Hello Pavel,

I think, you forgot this lens to add it to the compatibility list.
Or is there any other reason?
Truely, the lens works very fine with the GXR.

Thanks for adding. :D

I tried it before, and was just fitting in the module.

Nice lens by the way.

In the same time, you can add the Canon RF 35 f1.5 to the list of compatibles lenses. It is a LTM lens.
 
Add compatible lenses

FED 100mm f6.3 ltm (pre-WWII)

Chiyoko (Minolta) 45mm f2.8 Super Rokkor ltm (1947->)

The Russar MR-2 20mm f5.6 ltm also fits safely (P=R in Cyrillic hence the confusion)

Please apologize my ignorance but what does "compatible" mean? Does it mean the lens fits physically to the GXR module and it's possible to take a picture, or does it guarantee that there are no artefacts like color shifts or smearing in the edges?

Thank you,

You have to be careful mounting some rangefinder lenses to be sure that part of the lens does not hit the shutter blinds or sensor. Not many lenses do not fit but Ricoh supplies a small plastic template that can test the lenses before they are fitted. This list is just a running balance of the lenses that have been tested and should fit without a problem and the few lenses that will not fit are noted as well.

This is not a guide to the actual performance of any lens which will vary - only a compatibility list that says that the lens will either fit without a problem or not fit as listed. In any case it is recommended that any lens that you buy should be tested with the checking device to be sure. The list merely allows you to get an idea of the lenses that should be safe before any purchase is made.

Quite a lot of the lenses that will fit in the GXR A12 mount will not fit on any other camera except a genuine Leica body of close clone (eg: the Jupiter-12).

Please let there be no doubt:

Leica Summitar 50mm f2.0 collapsible fits inside the lens checker in its collapsed mode. In fact it seems that the lens checker was designed around one of these lenses when collasped.

To add faith to theory I have had the same lens fitted to an A12 mount in its collapsed mode. Forget the pieces of tape - not necessary. But watch out for the Russian clone collapsibles they are much more likely to have a tangle with the sensor!

As a small side issue and for completeness: Some of the Schneider-Kreuznach DKL mount lenses actually protrude beyond their DKL-M42 adapter but there is plenty of room inside the M42-LM adapter to take this up without even worrying the camera's internal bits. Just like "normal" slr lenses they were all designed to clear internal mirrors and therefore the adapters seem to cover all "sins" in that regard.

An odd one and it is a compatibilty matter, but not exactly a Ricoh problem.

Some adapters M42-LM use an insert for the screw mount part so that the mounted lens can be revolved to true up it's markings. This makes them wider and not normally a problem. The RJ version of this adapter type a good one, and I can recommend it, but 58mm in width. I now have a very nice EBC Fujinon 50mm f1.4 in M42. It has it's aperture ring at the very back of the lens with a small rearward facing tab that must have been designed to lock into a mechanism in the oem camera. This tab blocks into the edge of a 58mm wide adapter on an attempted mounting and locks up the aperture ring. The tab could be ground/filed off very carefully but I think the easiest and more assured way is to find a narrower adapter. I have a Kiwifoto M42-NX adapter that is 54mm wide and the lens works very well with it as the tab and aperture ring rotate outside the mount.

Working on it, but for now the Fujinon 50mm f1.4 needs an adpter no wider than 54mm.

I have a range of Leica Rangefinder lenses. My 35 mm Summicron, 50 mm Summicron and 90 mm Elmarit all focus on infinity subjects (using the focus checker on maximum magnification) at the infinity lens setting. Not so my 21 mm Elmarit f/2.8 lens that gives infinity focus on the focus checker when the focus on the scale of the camera is close to 10 ft (or 3 m). This is a huge discreapancy. I am happy with the images that I get on infinity subjects.

Question: How truly compatible is the 21 Elmarit f/2.8. Mine is not the aspherical version. Should I suspect a problem with my lens construction, or is this "error" a result of some minor misalignment within the GXR module that only becomes apparent with my 21 mm lens. Or should I take no notice and always focus with the focus checker even when I know the subject is "at infinity". Could the focus checker be wrong?
 
Hi Glacio, I've detected the same phenomenon on my 2,8/21 pre Asph. Infinity is right between 3m and infinity on scale. I have no explanation for this. But good to know.
