Hi

The shop just let me try Elmar 50/2.8, a collapsible vintage lens with the M3. He said I shouldn’t try to digital because the lens might damage the sensor. I am tempted because I cannot wait for the film to be developed. Any trick to try this lens with the M10? Thanks

I'm pretty certain this lens won't damage anything on a digital M but the manual should have a list of lenses not to be used. 

In any case, and if in doubt, you can simply use it in the fully extended postiion - which is how you should always mount and unmount it.

You cannot withdraw is completely. I’ve been thinking to put f.e. a rubber ring between it, avoiding completely withdrawing.

Do you mean you cannot collapse it completely?

This lens is a superb little optic.

I think the only problem using the collapsible lenses on a digital camera is if you collapse it into the camera.

There are expensive elastic bands sold on the internet that you can put on the barrel of the lens to stop you collapsing it and hitting something inside a digital camera. Back in the days when the film CL was introduced in the 1970’s Leitz recommended putting half inch dymotape round the lens to stop it hitting the metering arm, not very nice and messy to remove.

[Hey You]

I have it.  It can be collapsed completely without problem or risk.

The only precaution you should take is to extend the lens when mounting and un-mounting, so that the collapsed portion of the lens does not contact and damage the focussing arm or move it out of alignment.

Does this apply to both the modern Elmar-M 2.8/50 (which was produced until not that long ago) and the vintage Elmar 2.8/50 lens? I am pretty sure you are correct with respect to the former lens, but things may be different with regard to the latter lens (then again, both lenses may just behave the same, I simply don't know because I only own the former lens).

I have one as well and it can be collapsed.

Excellent little lens.

Recurrent question. You may wish to do a search on the forum. See for instance the link below. Better keep the lens extended when mounting and unmounting the lens anyway as earleygallery said above.

I have a summicron 50mm f2 collapsible, no issues at all collapsing it in any of the digital leicas. Some other collapsible lenses may impact the sensor though, but the best thing you can do is simply measure the distance between sensor & mount and see if the lens would hit the sensor. If not, you should be safe (just make sure to unmount/mount them when they're not collapsed)

It is not only a matter of distance. You may wish to have a look at the link above.

It’s not the sensor that will be impacted with some of the older collapsible lenses (90mm) you need to worry about. Something much more fragile is between the mount and the sensor.

No. Just the same; the older one can also be collapsed on a digial body (once attached). Same warnings as above, of course.

I use the older one on my M9p and it collapses fully. Funnily enough it's annoying that I cannot fully collapse it fully  with the lens back cover :-)

Look for one of the deeper covers.

The easy answer is yes, the "modern" 50/2.8 Elmar-M can be fully collapsed while mounted. I have two and use (and collapse) them regularly on both my M240 and M8. But I do heed what's been mentioned above to have the lens extended while mounting and removing.

No problem with M240 & Elmar-M and few others
