Rangefinder separation and blackout from knocks and bumps was a much more common problem with these cameras when they were current than in the later cameras. Now, as the cement has deteriorated over time, it is even more fragile. When they switched optical cements I do not know.

Its not like the prism falls out of the camera or anything. - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
