The Fed-4 camera is intended for
amateur and professional photography on black-and-white
and colour standard perforated 35 mm. film.
The camera will operate reliably
during many years providing it is correctly handled
according to the rules laid down in the present
Do not exert excessive efforts in
handling with the camera, protect it from dust, try not
to touch its optics.
There may be some negligible
discrepancies between the description and the camera as a
result of continuous development of the

The main units of the camera are the
body which houses the mechanisms of the shutter,
automatic releaser, synchronizer, exposure meter,
range-and-viewfinder, picture counter, and the lens with
diaphragm, depth-of-field and distance scales. The lens
is fastened to the body with the aid of a

Preparation of the camera for shooting
consists in its loading by the magazine with film. The
loading is carried out under ordinary soft lighting
By turning the case nut unscrew the
screw retaining the camera in the case. Remove the camera
from the case.
Raise the lock shackles of camera
cover 18 and turn them half-way round as far as they go
according to Fig. 3.
Then. pressing with the thumbs on the
cover, shift it in the direction of the arrow as shown in
Fig. 4 and take off the camera.
Having pulled out the free end of the
film about 10 cm. long from the magazine, fasten it on
the reel in such a way that the spring tooth enters one
of the film perforations as shown in Fig. 5.
Fit the take-up reel on the bush and
then place the magazine in the camera.
Turning shutter cocking lever 17, wind
the film onto the take-up reel. At this point the film
should be slightly stretched and the teeth of the
sprocket should enter the perforations of the film. This
moment of loading you can see in Fig. 6.
Put the cover on the camera and push
its edge under the shield. Turn the lock shackles
half-way round and lower them into the
The unexposed film is fed to the
picture aperture by cocking the shutter twice, pressing
on shutter release button 16 after each cocking. The
shutter cocking lever should be turned each time as far
as it goes, otherwise the button will be interlocked, and
when pressing on it the shutter will not
Now, by turning the scale of the
picture counter dial 6, set the "O" point against index 5
as shown in Fig. 7.
Fig. 7 shows the film-type indicator
dial arranged on the picture counter. Conventional
designs of film types are marked on the dial.
Upon completing the loading of the
camera with the film, turn dial 7 until the symbol
corresponding to the type of film with which you loaded
the camera is aligned with index 19.
The film indicator dial will help you
to remember by what type of film the camera is loaded
when you want to take pictures after a long
Then turn dial 26 of the calculator
until the number corresponding to the sensitivity of the
film put into the camera ia aligned with calculator index
27. The calculator is shown in Fig. 11.
So, you have loaded the camera and may
Having chosen the place for shooting,
open the camera case, take the cap off the lens and
looking through the eyepiece of view-and-rangefinder 20
check how the chosen subject is arranged within the
limits of the field of view of the view-finder.
In order to set the camera at an
accurate focus, first turn dioptric correction ring 12
and focus the view-finder by your own sight.
Focus the lens. With this purpose by
turning distance scale 23 align two images seen in the
circle of the field of view of the view-finder, as shown
in Fig. 10, into one.
When photographing the remote
subjects, or if the distance to the subject to be
photographed is known, the lens may be focused by the
In the case of photographing the
subjects having a significant stretch to the length or
when shooting a series of subjects located at different
distances from the camera, determine the value of the
necessary diaphragm by the depth-of-field scale and
diaphragm the lens by setting diaphragm scale 21 in the
required position relative to the index.
Depth of field scale 22 consists of
two rows of figures corresponding to the lens diaphragm
scale which are disposed symmetrically relative to
distance scale index 24.
When the lens is being focused, the
depth of field scale shows on the distance scale the
shortest and longest distances from the camera within the
bounds of which the image sharpness will be satisfactory
for each diaphragm value selected while taking
For example, in Fig. 9 you can see
that when the lens is focused at a distance of 1.1 m.,
the diaphragm being 5.6, all the subjects located at a
distance of 1.05 to 1.2 m. from the camera will be
sharply photographed. When the diaphragm is 8, the
subjects located from 1 to 1.25 m. from the camera are
produced sharply on the pictures and so on.
25 - exposure scale dial; 26 - diaphragm and
sensitivity scale dial; 27 - index; 28 - follow-up
pointer; 29 - meter pointer.
Then aim the camera at the subject to
be photographed and, turning the exposure scale dial 25
to either side, make follow-up pointer 28 coincide with
meter pointer 29 (Fig. 11). Then find the readings of the
It should be noted that in this
position the calculator will show a number of
combinations of shutter speeds and diaphrams. Any of
these combinations will give the same exposure. Select
the necessary value of the shutter speed depending on the
real conditions of shooting or by the diaphragm set
Fig. 11 shows the calculator with
combination: shutter speed 1/125- diaphragm 4; then,
shutter speed 1/60 - diaphragm 5.6; shutter speed 1/30
corresponds to diaphragm 8 and so on.
It should be kept in mind that the
exposure meter gauges the mean brightness of the subjects
to be photographed. In case the area of the subjects
which is important from the point of view of the plot
occupies a small part of the frame or considerably
differs by its brightness, you should better find the
exposure value for measuring the brightness when you are
standing in the immediate vicinity to this subject, i.e.
at a distance of 30 - 40 cm.
Protect the aperture of the photocell
from immediate rays of powerful light sources, otherwise
it may result in erros in determining the exposure
In case the light source is in front
of the camera it is good practice to put a sunshade on
Having determined the value of the
necessary exposure, raise slightly exposure head 13 and
turn it until the index registers with the selected value
on exposure scale 14 (fig. 2). Lower it back in
The exposure can be set only with the
shutter cocked. Do not turn the head in the interval
between 30 and 1.
The numbers on the exposure scale show
the exposure values provided by the shutter in fractions
of a second )1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125,
1/250, and 1/500). Letter "B" determines the head
position for obtaining prolonged exposures "by hand",
when pressing on the release button the shutter remains
open till the moment of button release.
The head of exposures is set on
exposure scale divisions 1, 2, 4, 8, and 15 somewhat
higher than on the other divisions; do not try by
pressing the head to lower it down.
Now aim the camera at the subject to
be photographed, check the position in the field of view
of the viewfinder, choose the necessary moment and
smoothly press on the release button of the
In taking ictures with the automatic
releaser, when the diaphragm and exposure are set, cock
the automatic releaser; with this purpose turn automatic
releaser lever 1 counterclockwise as shown in Fig. 12,
into the top position. Secure the camera on the tripod
and set by the viewfinder the necessary position of the
camera. Press on automatic releaser button 2 (Fig. 12)
and stand on the spot chosen beforehand. The shutter will
release in 9 - 15 seconds.
It is possible to cock the shutter
with the automatic releaser either released or
When photographing with a flash lamp,
the shutter should be set at 1/30 second, and the
diaphragm value is selected in accordance with the
sensitivity of the film, the distance to the subject to
be photographed and the lamp power.
For photographing place the lamp
reflector in race 8 and insert the lamp plug cord in the
synchronizer socket 3 (figs. 1 and 13).
The flash lamps can be connected and
disconnected with the shutter either cocked or
More detailed information on shooting
with flash lamps can be obtained by referring to
instructions supplied with lamps and to photography
On depressing the release button the
flash lamp is switched on simultaneously with the shutter
operation. The flash lamp can be also switched on with
the aid of the automatic releaser.
When photographing, the film is pulled
out of the magazine and wound onto the take-up reel. To
reload the camera for the next shooting, the film should
be rewound back into the magazine.
As soon as you take ictures of 36 frames, disconnect
the shutter mechanism. To do this, press the fluted end of disconnector
bush 15 (Fig. 2) downwards and turn the bush towards the letter "B"
Turning the rewind disc as shown in
Fig. 14, rewind the whole film into the
While rewinding the film back the lens
should be covered with a cap.
Complete rewind of the film will be
defined by the change of effort needed for pulling out
the film end from the take-up reel.
Open the camera as it was mentioned
above and take out the magazine.
Turn the shutter mechanism
