Hi all. I'm looking to get a rangefinder again. I used to have a Bessa R3A for a while which was a great camera. I particularly loved the viewfinder even though the 40mm framelines were basically impossible to see. For various reasons I sold it but am now looking to get back to rangefinders. I intend to use the camera for quiet situations and for when I want just something light and small. Lens-wise I intend to use either the Voigtlander 40/1.4 or a Zeiss/Leica 50. No other focal lengths.
So...I could get another R3a but where would the fun be in that!
Additionally, given the prices these command noawadys I started looking at the Leica M3.
For those who have used both, beyond autoexposure what am I losing with the M3? How do the finders compare between the two, is the M3 dimmer and is the rangefinder patch easier/trickier to see? Also, given a budget of £1000 for the body, is there anything else I should be thinking of? I suppose any other Leica 0.85x body is a candidate if the price is right?
