Thinking of trying out a Leica M6 and I figured first up is to decide on a lens. So I checked around and I think that the Voightlander ultron 35mm f1.7 would be where I would start. KEH has a M6 with a .85 magnification is the reason I started thinking about it. Given the 35mm focal length would a .72 or .85 rangefinder be preferable? And the next question is I wear glasses. Does the viewfinder have eye relief for people with glasses? I do not want a diopter as I wind up putting my glasses on and off constantly and it's a deterrent to quick photography.
