Collapse 50mm Elmar-M on M5?

[Rob-F]

Collapsing a 50mm f/3.5 or F/2.8 non-M Elmar on the M5 (or CL) will destroy the metering stalk. However, it is OK to collapse the 50mm Summicron, because the length of the barrel that moves is short enough that stops before reaching the stalk. (Yes, I have verified this--very carefully!)

The 50mm Elmar-M looks to me like the length of the moving part of the barrel is equally short. Does anyone know if it is safe to collapse into the M5?

I do not own an M5, but according to this http://www.cameraquest.com/m5.htm the Elmar-M cannot be safely collapsed on the M5.

Doesn't work on CL. Don't know about M5.

No, the Elmar-M cannot be collapsed safely on the M5. Put something around the tube, some rubber washers for instance.

+1, the meter stalk will hit the lens barrel.

This is why I never collapse any lenses - ever.

I have seen it done. The owner put a rubber spacer/ O-ring /gasket around the front element on the barrel. it was not very wide, but it kept the lens when ~90% collapsed from damaging the meters swing arm.
Yes, what Erik said works

I don't own an Elmar-M, but I wanted to ask this in case I should buy one and try to use it on my M5. I'd rather not have a lens that could inadvertently damage my M5! I'm comfortable with my collapsible Summicron, since it can't cause damage.

Thanks for the responses!

Just as a side note: I've tried on the CL and looked through the open film door what happens: it will not touch the meter, but a barrier that is in front of the meter, so the meter is not in danger.

Well, it looks like he's talking about the older versions, though. I'm not sure the Elmar-M (the latest one, that is engraved Elmar-M) was out when he wrote that.
