Zorki 10

From Camerapedia.org

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.
