I'm new to all this rangefinder business, but something that always amuses me is when I read about preferences for this (rangefinder) lens over that one because among other things it is lighter.
I know everything is relative, and one gets used to what one uses all the time, but compared to my SLR gear, my rangefinder camera and lenses weigh nothing.
I routinely prowl the streets with three old, motorized manual focus cameras, and one in particular, my motorized Nikon F2As with a zoom Nikkor 80~200 2.8 manual focus monster attached has a weight measured in tons, not pounds.
Oh, and I'll be getting the CV 85 in a few weeks, but my decision to buy it instead of the Nikkor has nothing to do with weight.
