I have the Zorki as well, complete with yak leather case.
To be honest, it's not the greatest camera (although mine works perfectly) - kind of a rangefinder Zenit E without the light meter. The viewfinder in particular is terrible. It's a hole with glass in front of it - no framelines, not even a rectangle. Just a vague hole. I've seen better viewfinders on a box camera.
Yes I know it's basic, but do you have the 4K? reviews I've seen say it's pretty bright and definitely very usable, the best of the Russian rangefinders in that respect. Having been used to using 1950's folders I can't imagine the viewfinder being any smaller or more tricky to use than those.
I have three old rangefinders: Zorki 4K/Jupiter 8 50/2, a Yashica electro 35 and a Ricoh RF500G
The Japanese cameras are electronic marvels while the Zorki is a Russian copy of an ancient Leica.
The Japanese cameras have nice brightline framelines, the Zorki doesn't. You look through a tiny hole in the back and there is no apparent frame at all. If you move your eye around the eyepiece it seems unbounded, like looking through a hole in a piece of cardboard. If you shift your eye around you can see anywhere you want, no obvious edge. Eventually if you peer through at a sharp enough angle, you see reflections bouncing around that shade to dark but there are no crisp sharp frame edges. It is nothing like the little viewfinder in my Fuji X10 or old Canon powershots where there is a sharp cut off at the edges of the VF.
If you were using this for serious photography, composition would be a wild guess. You'd be better off with a hot shoe mounted accessory and just use the official viewfinder for focusing. One good thing about it is that there is a lever around the film rewind knob that is a dioptre/VF focusing adjustment. It has a lot of travel so you can adjust for your eyesight.
The funny thing is that if I look to the right, I can see the prism. It is like having a mirror in the edge of the viewfinder with a secondary image. You don't see that if you look straight ahead fortunately but it isn't a sophisticated VF by any stretch.
I got my Zorki because it was cheaper than buying the 50mm lens on its own. I had to take my Jupiter 8 apart because it was almost impossible to turn the focusing ring. Applied a bit of Sudecreme antiseptic lotion as lube. Worked a treat, still going strong after several years.
I used to have a Zorki back in about 1977, so it's fun to have one again but I wouldn't bother using it.
