Until now, I don't know any film-camera quieter than my Olympus XA. Just took pictures yesterday in my japanese learning class from two people that sit about 2m away from me, facing me, but looked in another direction. I took 8 pictures, until they noticed...
Interesting. I mean - the shutter of the XA is really silent, but the mechanical film transport not that much.
I never had a Leica M camera, but had Bessa R3A for a while. The shutter was not all that loud (comparable to common SLRs), but the sound was very mechanical and steel-crushing-like.
