I purchased this colorful Zorki 2-C a couple of years ago from Roberts Camera's Used Photo Pro division.
the Zorki 2-C is a Russian knock-off of a Leica II. It's a surprisingly well built, heavy all metal rangefinder. I mounted it with an f/2.8, 52mm Industar N-61 screw type lens. Very inexpensive and surprisingly good.
The Zorki is fully manual. 35mm film is loaded on the bottom via removal of the bottom plate. You need to cut a longer leader on the film for this style of camera.
Speeds are B, 1/25, 1/50, 1/100, 1/250 & 1/500. As with cameras of this type if you want to change the speed you do it BEFORE you advance the film and which cocks the shutter. Why, no clue, but that's what I've read and have always done. There is no light meter. There is a viewfinder to focus and one for composition. Super basic.
I loaded the camera up with a roll of Arista EDU 400 and shot the roll around Indianapolis.
The Zorki 2-C is a handsome camera that I enjoy using.
