FED 50
Automatic miniature Rangefinder 35mm camera
Instructions for use
Since efforts are continually made to improve the reliability and performance of
the product, minor changes may be Introduced without special notice.
1. GENERAL DIRECTIONS
The FED 50 is a modern miniature camera intended for amateur
shooting on standard black-and-white and colour perforated film 35 mm
wide. The camera operates in the automatic and manual control modes.
In the field of vision of the view finder the information is available on the
shutter speed and diaphragm processed in the automatic mode. For
accurate framing of a picture the lighted frame provided with the marks
for parallax correction is available. The camera is furnished with a selfreset picture counter. The interlocking of a release button in the
automatic mode in the event of insufficient lighting as well as the
interlocking of the shutter cocking (which prevents the repeated or
incomplete cocking) are envisaged by the design of the camera.
The automatic system of the camera operates from a photocell which is
designed for long-term use. The replaceable power supply sources are
not required. Thoroughly familiarize yourself with the present
instructions before using the camera. The observance of all
recommendations set forth in the instructions will ensure the reliable
operation of the camera for many years.

11.OPERATION
Page 10
When the picture counter reads 36
pictures, press on the rewinding
button, which releases the film
transport mechanism (Fig. 13).
Unfold the handle on the rewinding
knob, rewind the film into the
magazine (Fig. 14). Open the rear
cover by pulling up the rewinding
knob, remove the magazine with
the film. The film transport
mechanism will be engaged
automatically upon the first
cocking of the shutter.
Load and unload the camera in the
premises or in the shadow,
avoiding the direct solar rays.
Shift the cocking lever as far as it
will go. Otherwise the lever fails to
return to the initial position,
indicating that the shutter has not
been cocked.
The rotation of the rewinding knob
upon cocking the shutter is
indicative of the fact that the film is
pulled normally. When shooting in
the automatic mode, the used filter
factor is taken into account
automatically.
While shooting, avoid getting of
direct rays from powerful light
sources to the photocell — this can
result in the errors in operation of
the automatic system.
Fig.13
The system of measurement and
setting the exposure in the
automatic mode is designed for the
most frequently occurring average
conditions of lighting of objects to
be photographed. In some cases it
is required to increase or decrease
the exposure. This is attained by
varying the preset film speed
relative to the speed of a loaded
film. First of all the correction of
exposure is recommended in
shooting on the reversible films.
The setting of the lesser value of
speed corresponds to the increase
in exposure and vice versa. For
example, in shooting on the
reversible film in the cases when an
object is located opposite a light
source, on the background of
Fig.14
Page 11
bright snow or on the sea coast in
sunny weather you are to set the
film speed equal to 40 or 50 units
by GOST/ISO instead of the film
speed equal to 64 units by
GOST/ISO. In the cases when a
light object is located on the dark
background, the value of preset
film speed is to be increased, e. g.,
set the film speed equal to 100—
125 units by GOST/ISO instead of
the film speed equal to 64 units by
GOST/ISO.
STORAGE RULES
The camera is a precise optical-and-mechanical device. Handle the
camera with care, keep it clean, protect from impacts, dust, dampness
and abrupt changes of temperatures, avoid the long-time effect of direct
solar rays on the photocell. Store the camera in the case. In doing so, the
photographic lens must be covered by a cap. Do not leave the camera for
a long time with its shutter cocked.

APPENDIX
RULES OF LOADING THE MAGAZINE WITH A FILM
The camera is completed with the magazine type 135M intended
for repeated application.
Take the reel out of the magazine and insert the film end into
the reel slot as shown in Fig. 15, a. Fold the free end of the film
twice according to Fig. 15, b and, pressing it by the thumb of the
left hand, pull the film out of the reel with your right hand. In
this case the
Fig 15
folded end of the film should pass into the reel slot
Pull the film so long as it will be fixed (Fig. 15, c).
Load the reel with the wound film into the
magazine. In this case the film end should enter
the slot of the magazine housing (Fig. 15, d).
Reload the magazine in the reverse order. To
avoid the film fault it is necessary to clean
the packing piece of the magazine removing the
dust and emulsion re ains from the film.m
