bencychin Posted October 24, 2017 Share #1 Posted October 24, 2017 Advertisement (gone after registration) Dear Senior members, I just received my m10 camera early October. Besides using the modern Leica lens, I do like the compactness of the old collapsible Leica lens of the 1950s. I have the old Leica ELMOM 50 / 2.8 and SOONC 35 / 3.5, both are in collapsible version. The m10 instruction booklet advises not to collapse the lens whilst mounted on the camera, as it risk damaging the camera and lens. Is my understanding correct? Thank you.

luigi bertolotti Posted October 24, 2017 Share #2 Posted October 24, 2017 (edited) Yes... not to collapse old lenses is a general advice which is better to follow, even if the effective risk of damage in some cases is not so significant : the only really comfortable to collapse are the last Elmar M 50 f 2,8 and the Macro Elmar M 90 f4. Btw... why do you mention the SOONC ? It's a Summaron 35mm f3,5... which is NOT a collapsible lens... (it can be "goggled", which is a configuration that works also on all new digital M bodies) Edited October 24, 2017 by luigi bertolotti Quote Link to post Share on other sites More sharing options...

I was thinking of Voigtlander Heliar 50mm 3.5 lens which is collapsible. Cheers! Quote Link to post Share on other sites More sharing options...
jdlaing Posted October 24, 2017 Share #4 Posted October 24, 2017 Collapse the 50 in your hand while not on the camera. Does the barrel protrude past the mount on the rear of the lens? That should answer your question. I believe there was a 90 or 135mm collapsible that could damage am M digital but that was the only one. 1 Quote Link to post Share on other sites More sharing options...

The Elmar dont protrude. So i now can use your recommended method of checking. Thanks for sharing your experience. 1 Quote Link to post Share on other sites More sharing options...

Yes, the old Elmar 90 collapsible is the most risky one... while, for instance I've experienced that the my Summicron 50 collapsible is "safe" on both M8 and M240.

I checked my old 50 and it’s okay as well. Quote Link to post Share on other sites More sharing options...
