A single-stroke M3 w/50mm Elmar, picked up at a flea market a couple of years ago.
As I found out how much fun the whole rangefinder thing was (I am a die-hard F Nikonite at heart), the Elmar was quickly replaced by an 11819 Summicron and a 90mm APO-Summicron followed a few months ago.
I recently found a bargain M4-P which sees more use than the M3 nowadays - mostly because it is still the 'new' camera. GAS being what it is, I've already started looking for a nice M4 to replace the M4-P, though. 🙂
