i was using a dSLR until i got myself a leica IIIf because of it's fancy looks. RF is a good camera for discreet street photographers. once i tried using a dSLR with a huge zoom to shoot a woman on the street and she ran and hid from the camera.
a RF is more friendly because it's small and people tend to think you're a small timer rather than a pro photographer. i ditched all my dSLR stuff because it's just too difficult to shoot with it.
and the lens distortion for RF is much much lower than slrs.
