The other thing about rangefinders is that the focusing is, IMHO, much more precise than with SLR's (especially autofocus. yuchhhh!) If you want to get a very shallow depth of field portrait, I think it is hard to beat Leica glass wide open. The out-of-focus areas are smooth and distinctive, and the in-focus areas are razor sharp. You might want to consider a user M2 or M3 with a Summicron-M (35 or 50), which can be found used for not quite as much $$$ as a brand new kit.
