I have never owned a rangefinder camera and have been considering getting one. I have always been drawn to the Leica mistique, but the prices scare me. On several occasions I have been about to order an M6 or M7 with a lens, then reality sinks in and I come to the conclusion that I can get a few Nikons with a couple of great lenses for that price. I would like a rangefinder because of its quiet operation, low profile, sharp optics. I have been thinking of candid portraiture and I think a rangefinder will stand out less than one of my Nikons with lens attatched. What can I expect from a Voigtlander Rangefinder? Why are they so inexpensive compared to Leica and others? Is it a reliable camera? What are the differences between the R2 and R3a? Are the lenses any good? Will I get images comparable to my current Nikon system? Will I be better off getting a used Leica or a new Voigtlander?
