I put the provacative title to get some interest. I have the guilt of owning most all formats and more than one camera for each, so I was struck by the light size and ease of use of these two: the Bessa R and the Leica M6, both available used, with a really big price difference. I had a Leica Reflex some years ago, and got into a row with Leica's repair depot which was not resolved to my liking. I sold all my Leica stuff and never looked back. The Bessa R is a lot lighter than the M6, which I guess is plastic vs metal, but what are the reliability factors of the two, considering the camera will not be my main one, as I am a heavy MF user. I realize there are devotees, aka fanatics on the Leica side, but how about mechanical reliablilty for the 50 rolls a year shooter?? Also, what about screw base vs bayonet lenses? How old are uncoated ones if any? Best Voiglander lens in the 30 to 60mm range?? Best Leica in the same ranges??
