I have found one thing that i can do with leica M that I am not able to do with SLRs (canon eos) When i shoot a portrait I sometimes feel that it is important to have full eye contact with the subject. After adjusting distansce and framing I can move a way for the Leica M viewfinder and look directly at the person without the camera moving and while gette a stranong eye - to ye contact iI can press the shutter - So far I have not missed a frame! The method is very good with Children as you can get them to ignore the camera and act more naturally. The second thing I love with my leicas is that I can see more than what gets on the picturer - shooting SLR is like a racinghorse with "Blinds" imho - fyi - etc and a :-) - ruben
