I'm not sure I want to do this, but wanted to throw the possibility out there. Would anyone be interested in trading their M6 0.72 or 0.85 for my R8 + 50mm Summicron-R? I've put about 20 rolls of film through it, and it's in near mint condition. The only thing I can find wrong with it is a speck or two of dust in the viewfinder. Otherwise, the body appears mint. The lens is an older Canadian 3-cam (not ROM). Glass is free of scratches, marks, haze, fungus, but there's some internal dust, as probably expected. I really like the R8, but think I may prefer the rangefinder.
