hi,
this isn't an easy answer because the answers are varied.
there are fixed lens rangefinders from Yashica, Canon, Olympus, Konica, Minolta etc.
Olympus in my opinion was probably the last to abandon the RF, and the have quite
nice fixed lens cameras, from the mighty 35RC to the highly sought after 35DC, and
the photographer's P&C camera, the XA.
