CAMERA DESCRIPTION
• SINGLE LENS REFLEX CAMERA
The ZENIT EM camera uses 35mm film cassettes which
are most popular among experienced photo amateurs.
The reflex lens system allows the photographer to see
through a prism and a reflection mirror what will be photo¬
graphed on film. Focusing through the lens on a ground
glass with help of microprisms ensures a perfect focusing.

When the shutter is released, the mirror is displaced the
time of shutting, the film is exposed and the mirror auto¬
matically returns in place back in the optical path.
A leather case is supplied with the ZENIT EM camera.
• FOCAL PLANE SHUTTER
The ZENIT EM camera is equipped with a focal plane
shutter. The particularity of this shutter consists in the
fact that the exposure time automatically adjusted through
the speed selector is controlled by the width of a slit that
will travel in front of the film during the exposure.
• INTERCHANGEABLE LENSES
The ZENIT EM camera accepts a wide range of inter¬
changeable lenses (with Pentax/Praktica thread) varying
from 8mm — fish eye lens allowing photography with
minimum room to back up — to 1000mm — telephoto lens
allowing closer photography of distant subjects — (see
figure 1).

USING THE CAMERA
• LOADING THE CAMERA
Under subdued daylight, load the camera as follow:
1) Open back of the camera by pushing the latch upwards
(see figure 2).
2) Push down on the rewind knob and turn left, then pull
it out (see figure 3) so that the cassette can be dropped
in the empty film chamber.
3) Push down tne rewind knob and turn right to lock it in
place.
4) Insert film lead in one of the slots of the take-up spool
and give half a turn to the spool (see figure 4).

5) Cock the camera shutter by turning the film advance as
far as it will go (see figure 5). Make sure the sprocket
teeth engage in the film holes. Check position of film in
film tracks of the exposure gate.
6) Close the back.
7) Advance the film by winding the lever and releasing
the shutter twice (see figure 6) so ihat the unexposed
part of the film moves in front of the shutter curtain.
Every time you wind the film advance lever, the rewind
knob should also turn. If not, reopen the camera and
check carefully the position of the film.
8) Adjust the exposure counter dial by matching the figure
0 to the index mark (see figure 7). Afterwards the ex¬
posure counter will register each exposure automatically
as the camera is cocked.

9) Set the film speed dial according to the film sensitivity
used. The sensitivity scale ranging from 16 to 500 (see
figure 8) indicates the film sensitivity in ASA units. In
the opposite window, figures from 13 to 28 indicate the
film sensitivity in DIN degrees. Place the film speed
index mark according to the film sensitivity used either
in ASA units or in DIN degrees.
• SETTING THE LIGHT TIMER
The ZENIT EM camera is equipped with a built-in light
meter not coupled to the lens (see figure 9). The light
meter permits reading the light intensity on the subject.
Two adjustments must be made to ensure a correct ex¬
posure: shutter speed and aperture of the lens. The photo¬
electric cell enables you to compute these adjustments.
