Zorki-4
ATTENTION!
This Instruction Manual contains brief characteristics and essential operating principles of the
"Zorki-4" camera; it is not intended as a photographer's handbook.
Before proceeding to take pictures, study the operation of the camera and its handling instructions
presented in this Manual.
Minor differences between your camera and the Manual may be due to ever-advancing
development of the camera design.
Do not direct the lens at the sun in order to avoid burning through the shutter curtains because the
lens acts like a powerful collecting piece.
The lens should be screwed in and out of the camera only by the knurled portion of the depth-of-
field scale ring (the greatest diameter of the mount).
To avoid the damage of the camera set the exposure speeds only after the shutter is cocked.
Do not rotate the shutter speed dial in the interval between "30" and "1".
Do not turn the release button, if not necessary, while releasing the shutter to avoid the cutting out
of the shutter setting mechanism.
While setting the camera shutter, always turn the setting lever up to the mechanical limit to avoid
blank frames on the film.
Purpose
The "Zorki-4" is intended for a wide range of versatile photography; it is used with equal success
by skilled amateur photographers, camera men and scientists.
Description
The "Zorki-4" (Figs. 1 and 2) is a compact roll-film minicamera provided with a flash synchronizer
and a self-timing device (automatic releaser).
The camera uses a standard perforated 35-mm motion picture film. The camera magazine
accommodates 1.65-m length of film, sufficient for making 36 exposures, the picture size being 24 by
