Zenit ET is a 35mm film SLR camera manufactured by Vileiskiy Zavod Zenit, (Vileiskiy Plant Zenit), , near Minsk, former USSR, produced between 1982-1993 with quantity 3.000.000. Зенит is the Cyrillic spelling of Zenit.
Zenit ETs also exist without aperture automation and without a built-in meter. They offered various finish materials and colours like silver, black, bronze, or green. This camera is an attempt to modernize the Zenit EM. Initially it looked just like an EM with new lettering, with new designs on the dials. Some variants also lack strap lugs.
The cameras produced in Vileiskiy Plant Zenit of MMZ-BelOMO are a complete remake of the earlier Zenit ET. The shape and features remain the same, but more plastic parts are used, including the top cover, bottom plate, and film advance lever on some cameras. BelOMO also supplied the multicoated Helios 44-3 58mm preset lens for use with the ET models lacking aperture automation.
