I don’t want to be rude, but Marco doesn’t seem to know what exactly he wants, just a camera. It’s difficult to help or give a quick advice without diving into the whole topic of photography and equipment. Asking about a folder camera and in the same breath deciding to go for a different type rangefinder… hmmm…
Marco – if you’re concerned about the cost of Bessa R series then guess what – Bessa III is rumored to sell for $100,000. In euros that’s 1,000,000. Well, not that much, but still much more expensive than any top-of-the-line R.
Since you still seem to be in an introductory stage to rangefinders I would sincerely advise to start with an old Russian type (Fed, Zorki, Kiev) which won’t set you back more than €50, even less. That way you’ll get a proper rangefinder that will do everything (manual) Bessa does and get a taste of what a rangefinder is all about. You’ll save $$$ if you discover it’s not your game. Plus for additional €20-30 you can get an old folder camera (even Bessa) at your local flea market that will function exactly the same way as the new III.
See - €50-70 and you’ll have two cameras that are very acceptable substitute to the expensive modern brothers. Then when you discover you love it you can start spending more to get better build quality, better lenses, built-in meters, AE priority, etc, etc.
