My road to Leica went like this:
Zorki 3m..... Focus? who needs focus?
Zorki 4k.......shutter speeds inaccurate
Bessa R.... well I didn't buy but I considered it for a while
Contax G1.... great camera and lenses, horrible squinty Viewfinder
Leica M6ttl... The perfect 35mm camera. I can't afford the lenses but its still a great camera.
I could have save a lot of time and money just buying a Leica to start with.
I use two CV lenses and they are wonderful, only my 50 is Leica glass.
Im not saying you should buy a Leica but consider this. If a Leica is what you want, you won't be happy with anything else.
