All I know is that once I used rangefinders (Leica M), rangefinder like cameras (Contax, Fujifilm, etc.), and high-end P&S cameras (film in the 90s, digital now), I never felt good about a SLR/DSLR again. I'm trying to force myself to use a DSLR again right now, but it isn't working out. Great quality, but no fun.
