Elektra-112 is a Soviet small-format automatic rangefinder camera manufactured by the Leningrad Optical and Mechanical Association ( 1980 - 1984 ). A total of 22,800 copies were produced. In the USSR, the camera was in limited demand due to the high price (160 rubles ).

- Set the photosensitivity of the film by a ring located on the lens barrel . Values of photosensitivity from 16 to 500 units. GOST.
- The Electra-112 camera is an automatic machine with aperture priority . Exponometric device with cadmium sulfide (CdS) photoresistor . Exposure compensation is possible only by changing the photosensitivity value of the film. When applying filters, corrections are automatically made for their density.
- In automatic mode, the shutter works out continuously from 2 seconds. up to 1/500 sec. Aperture values are set manually from f / 2.8 to f / 22.
- In the field of view of the viewfinder are the LEDs for controlling the exposure device. Duplicate LED indicators are placed on the top panel of the device.
