Excellent lens. The lens mount to film plane distance on an M3 is also 27.8mm and I would imagine the shutter is a similar distance in front of the film plane. You should be fine collapsing the lens. Has there been any documented cases of sensor damage from collapsible lenses?
Edit: a few threads on this subject on leica forum. Best to proceed with caution. A few people reporting that 50mm elmar is fine to collapse, but I suppose it depends on which exact version of the lens and which digital M cameras.
