Advertisement Posted August 30, 2022 Posted August 30, 2022 Hi Rva, Take a look here M11 and LEICA Elmar-M 50/2,8 11823. I'm sure you'll find what you were looking for!
a.noctilux Posted August 30, 2022 Share #2 Posted August 30, 2022 Yes, go for it. I had two in different periods ( one silver + one black) for many years using on film and digital Leica M without any trouble, collapsed or not. Now I replaced them with Summarit-M 2.5/50, lighter, more aperture blades for light balls, almost as compact and no need to collapse/uncollapse when in use. The new wise suggestion I learn here is, mount&unmount with the lens "uncollapsed", even if when I used, this was no concern and no accident. Link to post Share on other sites More sharing options...
rramesh Posted August 30, 2022 Share #3 Posted August 30, 2022 (edited) On an M10 it's perfectly safe to collapse it. However the recommendation is not to mount or unmount the lens when collapsed, as it could hit the sides of the mount where the sensor, rangefinder focus roller etc are located. Should not be a problem with the M11 as well, I think. Edited August 30, 2022 by rramesh Link to post Share on other sites More sharing options...
Rva Posted August 30, 2022 Author Share #4 Posted August 30, 2022 As one member mentioned, the best way would be to contact either a Leica Store dealer or Leica Customer Care and ask them directly. Link to post Share on other sites More sharing options...

For instance 2/50mm Summicron (screw-mount) has less than 14mm when it is collapsed. I will definitely ask Leica support to be sure. Link to post Share on other sites More sharing options...

pegelli Posted August 30, 2022 Share #7 Posted August 30, 2022 Advertisement (gone after registration) I have the same lens, I just never collapse it on a digital body, same with my Elmar 50/3.5. Never even dared to test if it was OK or not. On my M2 both collapse fine without touching anything inside. Link to post Share on other sites More sharing options...
lct Posted August 30, 2022 Share #8 Posted August 30, 2022 Great lens on the M11. The lens does not touch anything into the body when retracting it but the tube is very close to the roller cam (on M6J below) so better keep the lens extended when mounting and removing it as usual.

Rva Posted August 31, 2022 Author Share #13 Posted August 31, 2022 Having a chance to compare this Elmar-M 50/2.8 with Summicron M 50/2 (serial numb. 47xx), I am surprised that Elmar.M is sharper than Cron. It was just a quick test from a tripod. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

If you redo the test and get the same result, your Summicron might be in need of some adjustment. The Elmar is really sharp indeed, but the Summicron should be the same, in particular at f2.8 Link to post Share on other sites More sharing options...

tom0511 Posted August 31, 2022 Share #19 Posted August 31, 2022 I think to remember the collapsible to be quite good specially at shorter distances. What people say. I didnt compare myself. Link to post Share on other sites More sharing options...
Rva Posted August 31, 2022 Author Share #20 Posted August 31, 2022 It might be a silly question, but what is the reason to rotate a front ring on the lens (marked in red)? To start focusing, I have to extend the tube. Then rotating the focus ring, the tube automatically collapses or extends. The aperture ring is evident. But the front ring? Welcome, dear visitor!
