The Zorki was a product of the Krasnogorsk Mechanical Factory (KMZ), which also produced the Zenit single lens reflex camera (SLR). The first Zorki cameras were inexpensive Leica II copies just like the FED, but later models were considerably different from the Leica.
When using most Zorki cameras, the shutter speed should only be set after the shutter has been cocked. Setting the shutter speed before the shutter is cocked can permanently damage the camera. This especially affects all Zorki cameras with slow shutter speeds under 1/30 of a second, in particular the Zorki-3 and Zorki-4.
The first Zorki was the Zorki (mistakenly often called "Zorki 1", although it never had any number in the name), an exact copy of the 1932 Leica II rangefinder. It featured a 50mm f/3.5 Industar-22 lens, a collapsable lens which looked like the Leitz Elmar but was actually a copy of the Zeiss Tessar. Introduced in 1948, the "Zorki" was the first 35mm camera made by KMZ. The Zorki S of 1955 added flash synchronisation.
The Zorki 2 (1954) was similar to the Zorki but featured an updated rewind mechanism, a self timer and strap lugs. There was a later flash version called the Zorki 2S.
Introduced in 1951, the Zorki 3 was somewhat similar to the Leica III. It offered a number of improvements over the original Zorki, including a large combined viewfinder with the rangefinder builtin, a removable back, and a larger and faster Jupiter-8 (lens) (Zeiss Sonnar copy) lens. It also added a new mechanism for slow shutter speeds with a separate selector dial on the front of the camera. This mechanism was unreliable, so the improved Zorki 3M of 1954 (also produced in 1955) combined all of the shutter speeds on a single dial. The Zorki 3S, introduced in 1955, was a Zorki 3M with flash sync.
The Zorki 4, 1956, was a Zorki 3S with self-timer added. The Zorki 4K was identical but used an advance lever instead of the old-style wind knob. With over 2 million units produced, the Zorki 4 was the most successful Zorki and has a reputation as one of the best Russian cameras, although the self-timer and slow shutter speeds were unreliable. The Zorki Mir of 1959 was a lower-cost Zorki 4 with fewer shutter speeds.
The Zorki-35M full-frame 35mm coupled-rangefinder camera was a project undertaken by KMZ designer N. Marienkov during the late 1960s (the "M" is his "signature" camera; he also designed the Zorki 3M and the Zenit 3M). It was based on the body of the Zenit E and some of the advanced design features of the Zenit D, but as a rangefinder rather than SLR camera. It was to feature bright-line frames in the viewfinder for 50mm and 85mm lenses, with the entire field of the viewfinder corresponding to that of a 35mm lens. Other advances included automatic parallax compensation, speeds from 1 to 1/1000 sec. and a modern body design. It was probably an attempt to make an updated alternative for the then aging Zorki 4. At least two hand-built prototypes of this camera are known to exist, and the KMZ archives list it as a "project", but it never went into production.
The Zorki 5 was an updated model similar to the FED 2. There were two different versions, the first (1958) having an Industar-22 lens and the second (1959) having an Industar-50. Like early Leicas, the Zorki 5 was loaded with film by removing the bottom plate. The Zorki 6 was identical to the later version Zorki 5 but with a removable back for easier loading.
The Zorki 10 was a modern-style 35mm rangefinder camera with a selenium light meter and shutter priority automatic exposure introduced in 1964. The Zorki 11 was a cheaper model without the rangefinder, and the Zorki 12 was a variant using Agfa's Rapid film cartridges. All three variants had fixed (non-interchangeable) lenses.
The Zorki 10 is a fixed-lens Zorki coupled rangefinder camera with an integrated light meter. Selenium meter cells surround the lens. This was the first fully automatic camera produced in the former Soviet Union, as well as the first to use ASA/DIN markings rather than the Soviet GOST numbers, however these ASA numbers were still mostly useless as they didn't match any known film speeds (some Zorki 10 cameras apparently had GOST numbers instead of ASA though, as it's shown in a Polish camera manual).
The shutter release is a small lever protruding from the right-hand side of the lens. Shutter speeds from 1/30s to 1/500s were available in automatic mode. It also provided a B (bulb) setting, though there is no way to attach a cable release. Apertures from 2.8 to 22 with constant shutter speed of 1/30 s could be set in manual mode, intended for use with an electronic flash. Flash sync is possible at all shutter speeds through the PC terminal. There is an accessory shoe provided, but it does not sync with flash.
The Zorki 11 is a Zorki 10 without the coupled rangefinder mechanism, but with distance symbols visible in the viewfinder.
