Zenit-18 - Soviet small-format single-lens reflex camera with automatic exposure control (aperture priority) based on its measurement using a trans-lens TTL exposure meter.


The Zenit-18 camera was developed on the basis of the Zenit-19 semi-automatic camera. Produced at KMZ from 1980 to 1986.

Zenith 18 1

For the first time in the USSR, a lens with electrical transmission of aperture values ​​was used (light measurement on an open aperture). On devices of early releases, an FZL-80 shutter was installed with a synchronization speed of 1/60 s, later it was replaced by a more reliable FZL-84 shutter, a synchronization speed of 1/125 s.

Zenith 18 5

The release of Zenit-18 was discontinued due to the high price of 540 rubles (it had low demand) and the unreliability of the shutter in favor of the Zenit-Avtomat camera.

Interchangeable lenses with electrical transmission of aperture values ​​were not mass-produced.

A total of 7.001 pieces were produced.

Non-serial samples (prototypes) are known as Zenit-Electro, Zenit-20. There was a project to produce an automatic camera "Zenith-18" based on the camera "Zenith-16". Developed by "Zenith-21" ("Zenith-18" with lens mount "K bayonet"), not mass-produced.

Specifications Zenit-18

  • The type of photographic material used is 35 mm perforated photographic film 35 mm wide (film type 135) in cassettes. The frame size is 24×36 mm.
  • The case is metal, with an opening back wall, a hidden lock.
  • Shutter cocking and film rewind. The trigger has a transport and working position. Rewind roulette type. The frame counter is automatic, self-resetting when the rear wall is opened.
  • Shutter with electronic control, curtain-slit with vertical movement of two pairs of metal lamellas. Shutter speeds - from 1 to 1/1000 s, "V" and "D". Sync speed with electronic flash - 1/125 s (early cameras - 1/60 s).
  • Central synchrocontact "X", cable synchrocontact.
  • Standard lens (with "jumping" aperture) - "Zenitar-ME-1" 1,7/50 or MS "Zenitar-ME-1" 1,7/50 (multi-coated). Electrical transmission of aperture values ​​to the exposure meter of the apparatus. Diaphragm iris two-lobe (square opening of the diaphragm).
  • The diaphragm repeater is missing. Lock release button when carrying.
  • The lens mount type is a threaded connection M42 × 1/45,5.
  • Focusing screen - Fresnel lens with matte ring and microraster, Doden wedges. The viewfinder field of view is 22,8×34,2 mm.
  • TTL exposure meter (beyond objective exposure metering) with cadmium sulfide (CdS) photoresistor. Automatic setting of shutter speed at an open aperture. Arrow indication of the approximately worked out shutter speed in the viewfinder field of view. When using interchangeable lenses without electrical transmission of aperture values, light measurement is performed at the actually set aperture (at the working value). Arrow indication of the approximately worked out shutter speed in the viewfinder field of view.
    • The automatic mode is switched on by the shutter speed setting head, it is possible to set the shutter speed manually (if there is a power source).
  • Film sensitivity range 16 - 1000 units. GOST.
  • When filters are used, corrections are automatically made for their density.
  • Exposure compensation is possible by changing the film sensitivity value.
  • Power supply for automatic exposure metering and shutter - four disk nickel-cadmium batteries D-0,06[3] or four mercury-zinc elements RTs-53[4] (modern analogue of RH-625[5]). LED control of the validity of the power supply.
  • Mechanical self-timer.
  • The device was equipped with an eyecup with the possibility of installing diopter lenses (to correct the photographer's vision).
  • Tripod socket with 1/4" thread.

According to the catalog of 1200 cameras of the USSR, it has the following modifications:
