Zorki-6 and Jupiter-3
One of my favourite USSR made cameras is this Zorki-6 from 1963. As you can see it has a lever wind, hinged back, self-timer, eye piece focussing and a wide RF base. There's no built in meter which is probably a good thing as those meters from that era that have survived are rare if they work. (The light ages them and so the camera must be kept in the dark to maintain it. That is probably why hand held meters with cases like the Westons and Leningrads still work after many years.)
The lens on it is the Jupiter-3 f/1.5 50mm from 1957, fast and expensive. It's a good lens but I think the Jupiter-8 and Industar 61's are a better bet. The first Industar 61 has the best chance of being good as they are not sold so often and there's less chance of damage and abuse but that's just my opinion. By the way, the lens takes a 40.5mm screw in filter and lens hood like all standard USSR made lenses. It took a long time for the West to catch up with this simple innovation.
Zorkis were made by KMZ until the mid to late 1970's, the last model was the rare Zorki-12. The Jupiter-3 was made from 1948 to 1988 and is based on the old Zeiss design and has a bit of character and is really about 52 or 53mm. I think the optics have changed a bit over the years, probably as more modern glasses became available. Mine is an early one from 1957 and is coated; it has, but you can't see it, the red 'п' on the front.
