Danishtripod Posted January 22, 2019 Share #1 Posted January 22, 2019 Advertisement (gone after registration) I recently purchased a 1951 vintage 85mm f1.5 in beautiful condition. When I've tried to mount in on my M4-P the focusing cam on the lens does not line up with the roller on the cam on the bodies focusing lever. On the 85mm, I've noted that the lens surface the focusing cam rides on is not a 360 degree circle like most lenses, it's a small tab about 10mm wide with what I would describe as a ramp leading up to it. I've tried two different adaptors, one doesn't get it far enough to connect and the other one gets it close enough that the cam roller touches the "ramp" part. Has anyone had any similar problems and did using either the genuine Leitz adapter for a 90mm or one of Voigtlanders adapters work. I'd really like to use the lens since the iiif it came with is in need of rebuild before I can shoot with it. Thanks much in advance. Link to post Share on other sites More sharing options...

Ecar Posted January 23, 2019 Share #2 Posted January 23, 2019 Hi & welcome, Just dug out my Summarex and it has an original 9cm Leitz adapter - see attached pictures. Hope it helps. FWIW, I have had similar issues with other vintage lenses when using the "wrong" adapters. Welcome, dear visitor!

Danishtripod Posted January 23, 2019 Author Share #3 Posted January 23, 2019 Thank you kindly... I will have to find one of those now. I think they’re readily available on the auction site. Link to post Share on other sites More sharing options...
Ecar Posted January 23, 2019 Share #4 Posted January 23, 2019 (edited) Indeed. The good news for you is that 9cm original adapters are much easier to find than those made for other focal lengths. Edited January 23, 2019 by Ecar Link to post Share on other sites More sharing options...
Danishtripod Posted January 23, 2019 Author Share #5 Posted January 23, 2019 I looked and indeed they are. I'm making the assumption that your lens lines up properly for the focus tab when it's on an M body. Link to post Share on other sites More sharing options...
Ecar Posted January 23, 2019 Share #6 Posted January 23, 2019 The lens focuses perfectly, the tripod mount is where it should be (right in the middle) on all my M bodies. Not sure what you mean by "focus tab", since there is none present on the focus ring. However, I noticed the focus marks on the barrel are not aligned right on the top middle but slightly tilted to the left (about 20°) - perhaps so that they are easier to see when using the finder ? Not sure, but I have a few other vintage LTM lenses that show the same characteristic and it's not an issue in practice. Link to post Share on other sites More sharing options...
Danishtripod Posted January 24, 2019 Author Share #7 Posted January 24, 2019 Advertisement (gone after registration) Focus tab - probably not the right word. The part on the lens that contacts the cam roller inside the body. It’s on the bottom in your photo, it moves toward and away from the body as the focusing ring is turned.

Ecar Posted January 24, 2019 Share #8 Posted January 24, 2019 I see. Well, focus is perfect with my copy of the lens with that particular adapter and all my M bodies - so I guess the answer to your question is 'yes'. Unless your lens has other issues, it should work with yours too. Link to post Share on other sites More sharing options...
