With the diaphragm lever set at index mark "A", the spring-loaded
diaphragm operates in automatic mode. This device provides for fo-
cusing with the diaphragm fully open. At pressing the shutter re-
lease button the diaphragm automatically closes to a pre-set
value.
To check the depth of field set the diaphragm manually. In such a
case bring the automatic diaphragm lever opposite to index mark
"M" or press the shutter release button till a definite stop.
Loading the camera
The camera should be loaded in the following order:
pull the lock latch upward to open the back door;
1.
pull the film rewind knob up and place the cassette with the film
in its seat;
2.
return the rewind knob to its original position and fix it by turn-
ing in the direction of the arrow;
3.
pull the film loading end out of the cassette as long as to the
camera edge and insert it into the groove of the take-up spool
in such a way that a sprocket tooth would enter the film perfora-
tion hole;
4.
close the back door;
5.
cock the shutter by turning the lever as far as it will go and
press the shutter release button. As the shutter is cocked, the
film is advanced by one exposure. To transport nonexposed film
to the film gate, cock the shutter two times, pressing the re-
lease button after each cocking.
Should the film be wound tightly in the cassette, the film rewind
knob will rotate when the shutter is being cocked. If the film is
loose in the cassette, the film rewind knob will fail to rotate at
the first frames;
6.
bring figure "0" of the exposure counter dial opposite to the
index mark. Set the exposure counter only when the shutter is
cocked.

SETTING THE FILM SENSITIVITY
On the film sensitivity scale there are figures 16, 32, 65, 130, 250,
500, indicating film sensitivity in GOST-ASA units. The opposite
side of the scale carries figures 13, 16, 19, 22, 25, 28, indicating
film sensitivity in DIN grades.
To set film sensitivity (for example, 65 GOST-ASA units), turn the
diaphragm scale till figure 65 of the film sensitivity scale would ap-
pear opposite to the index mark on the diaphragm scale. The film
sensitivity is set in the same way if the film is marked in DIN
grades.

EXPOSURE DETERMINING
Direct the camera to an object to be photographed. Match the cal-
culator pointer with the needle of the exposure meter by turning
the shutter speed scale. Using the scales find a number of combi-
nations of shutter speeds and apertures. Each of these combina-
tions enables to obtain a negative of normal density. Figures from
500 to 2 on the shutter speed scale show shutter speed values in
fractions of a second and those from 1 to 30 show whole seconds.
Black figures on the shutter speed scale of the calculator corre-
spond to the figures of the shutter speed scale of the shutter. The
shutter speed and the appropriate apertures chosen depending on
the subject to be photographed should be correspondingly set on
the camera and the lens. For example, figure 125 of the shutter
speed scale would match figure 5.6 of the aperture scale. It means
that with the aperture of f/5.6 the shutter speed of 1/125 sec
should be used; with the aperture of f/4 – the shutter speed should
be 1/250 sec; with the aperture of f/8 – 1/60 sec and so on.
If necessary, it is possible to set the required aperture by a select-
ed shutter speed.
Should the scales fail to match by half an interval, the lens di-
aphragm ring should be set into a fixed intermediate position in
