Aren't Contax I shutters rather unreliable compared to the Leica II or III shutters? A Contax II would be a fairer comparison in my opinion.
Contax II:
- Easier to load then a Barnack, no messing about with scissors or cards,
- Brighter Single viewfinder/rangefinder window,
- Longer rangefinder base allowing for longer focal length lenses
- And it was cheaper too at the time.
- No rotating shutter speed knob when firing the shutter.
The Leica plus-points are more of a personal opinion then actual hard facts.
Leica:
- Better ergonomics,
- Better looking
I don't have a Contax, but I do have a Kiev 2A, which in my opinion.
