I am on the verge of buying either an R4M or an R4A (the old guy purist in me leans toward the M) and my questions are: I've used a Bessa R for years and 1) is the shutter release sound any quieter-less-clanky than on the R?, and 2) is the rewind smooth and effortless compared to the surprisingly stiff rewind on the R?
Oh, also: Will my c/v grip accessory fit on the R4M/A?
I've been looking at an M6 (way more money) but I don't think you can mount anything wider than a 28 without an external finder. Correct me if I'm wrong.
