    Screwmount Leica's using M designed lenses.

    Hi, a Question for all the Leica fans. Can I use M mount lenses on an older Screw mount body with an adapter ? Do all the lenses work? the same, compared to a straight screwmount lens in distance from the film plane and will there be focus issues. I was thinking of mounting a Zeiss 50mm on a Leica IIIC

    Other than gasps of outrage, what are your thoughts ?

    No my friend, you can't.
    LTM bodies are compatible only with LTM lenses for too many reasons to write here, like focusing, longer flange-focal plane distance etc.

    You can do it the other way round only (i.e. mount an M lens on a LTM body with a suitable adapter)*
    apart from the difference in mount design itself, the registration distance of the two mounts are not the same, hence the asymmetry between what you can adapt to what



    *no, the other way about. sigh. quel buffon

    Only option in this regard is an early version of the Summicron 35mm that one could remove the M mount from to reveal a threadmount. I had one i still regret selling...

    You mean LTM lens in M body, yes?

    Here (link) is a discussion about converting M mount lenses to screwmount. I have no idea if it would work with the Planar but if you are serious about it, you could ask Don Goldberg. It sure ain't gonna be cheap, but maybe more affordable than one of the special edition 1999 Summicron 50s in screwmount (current BIN prices on Ebay around 2000 $). The only other options for a modern 50 to use on your screwmount body would be the Cosina Voigtländer Nokton 1.5/50 (first) version and the Color-Skopar 2.5/50. The Nokton is optically quite capable and not so difficult to find but it might feel a bit bulky on a IIIf. I owned the Color-Skopar 50 and was not overly impressed and would not recommend it. A Canon 1.8/50 in screwmount is a much better choice IMO, but then we are back to classic lenses.

    Voigtlander (Cosina) has built some magnificent modern lenses with the LTM screwmount. In particular the Nokton 50/1.5 and Heliar 50/2 lenses are terrific examples. So if you are looking for modern lenses to attach to your Leica LTM they are certainly out there.

    Of course, if all you want to do is convert a slightly newer Leica M-mount lens to screwmount then there are undoubtedly people who can do it. DAG is an option, as has been mentioned. Miyazaki Sadayasu in Japan has been known to do some of this as well, probably contact him through Japan Camera Hunter.
