I am about to venture from SLR land into the an area I know little about, Rangefinder Camera Bodies. I have reviewed the various threads relating to M6 vs M7 etc, But I am looking for someone to help me better understand the various rangefinder combinations. What is the difference between .58 .72 ,85 magnifications? I have always been more inclined towards the wider angle lenses. I am expecting that due primarily to the cost I would not venture below 24mm or above 90mm in focal lengths. Given this I am open to suggestions on what configuration I would be looking for. Also Open to suggestions on Body models. M6TTL or M7. What Leica over G2 etc.
