The camera has a built-in exposure meter using a photocell, a self-timer, a shutter setting lever, a synchronising device for flash bulbs and electronic flash. The camera accepts interchangeable lenses with M42×1 thread and mechanical back focal distance of 45.5 mm. With the help of extension tubes ZENIT-EM camera may be used for reproduction works.

  • The camera and HELIOS-44M lens are provided with a mechanism of automatic pre-set diaphragm. The shutter release button being pressed, the diaphragm automatically closes to the pre-set value;
  • Fresnel lens and diaphragm, fully open at the moment of viewing, ensure uniform image brightness of the object to be photographed in the viewfinder; micro pyramids in the center provide for perfect image sharpness;
  • Exposed film is rewound with the shutter disengaging bush being fixed;
  • a new kind of a take-up spool simplifies the process of film loading;
  • the back door lock latches automatically;
  • The carrying strap, attached to the camera eyes, makes the camera possible to carry without its case.
