satijntje Posted June 20 Share #1 Posted June 20 Advertisement (gone after registration) Not sure if a topic on this already exists, I did not find it. The user manual of the M11 does not recommend to use the 90mm f4 collapsible Elmar-M lens as it could touch the shutter or sensor of the M11. I did some measurements and found out that the metal square in front of the shutter is 1 mm more inside that the distance the back of the lens moves into the camera. So I took the risk and tried it. For me it seems to work well, even in a Position when the lens is completely in. I own this lens because its from my year of birth and it had a CLA 2 years ago, and therefore for me its a keeper anyway. Welcome, dear visitor!

Advertisement Posted June 20 Posted June 20 Hi satijntje, Take a look here M11 and Elmar-M 9cm f4 Collapsible from 1957. I'm sure you'll find what you were looking for!
UliWer Posted June 20 Share #2 Posted June 20 (edited) Then you have been lucky or the M11‘s interior differs from other digital M models. It is correct that the collapsed lens will not touch the shutter. It didn‘t touch the shutter of the M3 for which it was made and according to what I was able to measure the frame of the M3 which is in front of the shutter is closer to the flange than with any digital body. Though the „throat“ of the digital models is much narrower than for models for film. So when I measured the rear end of the lens and the narrowest part of the throat I was sure it would not fit, and it touched the „throat‘s“ side when I carefully tried to push the shaft down. It did so long before the shaft was fully collapsed. So I‘d like to recommend not to try to collaps the lens on any digital body. The risk that it will scratch the interior is too high.

J S H Posted June 20 Share #3 Posted June 20 Well, he tried it and it worked. So, not sure why you would advise against it. Leica always errs on the side of caution in their official recommendations, as some people are not good with mechanical processes. I have the same lens and also have observed that you can collapse into the M11. Tolerances are tight and it’s best to not mount the lens while it’s collapsed, as your alignment would need to be perfect. Link to post Share on other sites More sharing options...
darylgo Posted June 20 Share #4 Posted June 20 The M11 doesn't have the photocell at the bottom of the throat unlike other M digital models. The metering is done using the sensor. 1 Link to post Share on other sites More sharing options...

Of course everybody is entitled to find out himself, though I believe it is also a task of this Forum to give advise about what may be harmful. As this thread is in the section about M lenses, experiences are not limited to the M11. And I hold on to say that trying to collaps an old 90mm Elmar in a digital M camera causes great risks.

J S H Posted June 20 Share #6 Posted June 20 It’s pretty obvious that the lens collapses into the M11 with no issue. Your statement that the OP somehow ‘got lucky’ is incorrect and was misleading to anyone who might stumble by later. Link to post Share on other sites More sharing options...

You mean the Elmar and not the current Elmar-M i suppose. The manual does not say exactly this if i remember well. The risk is not to touch the shutter or sensor but to hit the roller cam with the bottom of the tube. Great lens anyway. Link to post Share on other sites More sharing options...

Your statement that the OP somehow ‘got lucky’ is incorrect and was misleading to anyone who might stumble by later. Of course, I did my homework before attaching the lens by measuring carefully the distances. There is a bit over 1mm air between the metal frame inside the M11 body and the tube of the lens. All this was done on my own risk, I do not take responsability of any damages that may occur!!! Link to post Share on other sites More sharing options...
elmars Posted June 21 Share #9 Posted June 21 As far as I know the M11 has (in opposite to former digital M modells) no restrictions for collapsable lenses. It is only recommended to collaps them outside the camera, as they can get a little longer if you tilt them at the end of the path. 1 Link to post Share on other sites More sharing options...
vha Posted June 21 Share #10 Posted June 21 But how did the pictures go? Would be interesting to see it paired with a M11. I recently bought back two of my old lenses, one of them beeing the 9cm collapsable, remember it gave wonderful portraits paired with Delta 100 or Fp4. Sine everything take longer time than expected its not been sendt to CLA yet. Looking forward to try it on my M10M. Link to post Share on other sites More sharing options...
lct Posted June 21 Share #11 Posted June 21 (edited) The M11 instruction manual states “Incompatible”. See excerpt below. Incompatible does not mean forbidden, but the Leica warranty will not work in case of damage due to infringement of these instructions. Welcome, dear visitor!

justj Posted June 21 Share #12 Posted June 21 "Summicron 50 f/2 with close up function" Does it mean Summicron 50 dual range? Link to post Share on other sites More sharing options...

Yes the Summicron 50/2 DR is also listed as "incompatible" by Leica. In fact it is a lens that must be mounted and unmounted with care, preferably when the focus ring is set at the infinity position. Don't ask me why. Works perfectly this way for me. 1 Link to post Share on other sites More sharing options...
UliWer Posted June 21 Share #14 Posted June 21 5 hours ago, vha said: Sine everything take longer time than expected its not been sendt to CLA yet. I asked Leica Customer care whether they could do something about my collapsible Elmar which was cosmetically perfect but optically totally weird. They told me that they wouldn‘t repair it for lack of spare parts. So I got another one (which was probably cheaper than the repair would have been.) Btw: one can use any collapsible lens fully extended…🤫 And even though the 90 Elmar is the largest collapsible lens it is smaller fully extended than most modern 90mm. The rigid 90 Elmar with 39mm filter thread has the same optics. Link to post Share on other sites More sharing options...
vha Posted June 21 Share #15 Posted June 21 I have talked to a repair shop in the netherlands that i have used before as well as buing gear that had cla there, so thats the plan eventually 🦥 Link to post Share on other sites More sharing options...
