What rangefinder system has an affordable range of lenses to handle the range of photography an slr covers (including macro, long zooms, etc). Medium format system cameras can compete to a degree but are significantly less portable than a 35mm slr.
How do you use polarizers on a rangefinder? Maybe I'm doing it wrong with the slr, but I orient it by looking at the result. I'm not sure how that translates to a rangefinder.
