I'm well versed in old cameras...I think the newest camera I have is a 500c from the 70's! I've got tons of rangefinders from this era, and I would have to say that the Leica & Contax are great, Canon very good, Minolta not so hot. The Zorki is just made very poorly. I'm sure there are tons of good ones out there, but this particular one is extremely sloppy. Nothing fits together well.
