Why rangefinder and not SLR?
I've recently started using a rangefinder and enjoy just about everything about it. I have a friend who has started "learning photography" that will be visiting soon and I know that I'm going to have to explain the choice of a rangefinder over an SLR. This fellow is quite technical so a "just because" isn't going to satisfy...
Please help me: why do we prefer rangefinders over SLRs?
