The device belongs to the 12th Zenith series and was mass-produced from 1977 to 1985.
Ergonomics and description
Model with a TTL lens exposure meter, exposure metering is performed at working aperture values (stop-down metering). Since the light from the pentaprism simultaneously enters both the photodiodes and the eyepiece of the viewfinder, focusing becomes difficult when there is a lack of lighting (despite the presence of a focusing screen with a matte finish).
The body is made of metal, the shutter is focal, curtain. The shutter speed head allows you to set shutter speeds without cocking the shutter, coupled with the exposure meter. The galvanometer needle displays the readings in the viewfinder when the shutter release button is pressed halfway.
Exposures are standard for Zeniths of that time: from manual, to 1 \ 500 seconds, there is a self-timer. Synchronization with flashes for 1/30 sec via front panel sync pin. The ISO ring is also paired with a light meter.
Loading film under the rear opening cover. Film rewinding is manual, the rewinding knob is retracted into the camera cover. The back cover lock is external, which causes certain inconveniences when working – all the time it tries to open, catching on something. The apparatus with Olympic symbols, the symbols were applied in honor of the 1980 Olympics, which took place in Moscow.
The Zenit-TTL viewfinder eyepiece is round, next to it is a connector for the RC-53 element (power supply of the exposure meter). The structural elements are protected by 4 certificates; for KMZ, these were the first serial models of a SLR camera with a non-objective exposure meter. In fact, this is the modernization of Zenit-EM, a camera with a push diaphragm mechanism, a selenium exposure meter and a focusing screen with a microrastr, produced from 1972 to 1984 (1988).
Zenith TTL for all the time produced about 1.6 million copies. Later versions (from 1982) had a brighter viewfinder and a center sync pin. It is found quite often on the market, it is not a problem to buy in excellent condition at a price of “less than a thousand rubles.” Experiments show that a non-working shutter is sold even cheaper.
