User Manual.
This manual contains a brief description of ФЭД-4 (FED-4) camera and the basic rules for using
the camera. It cannot serve as a photography manual.
Slight differences between the description and the camera may occur as a result of technical
modifications being introduced in the design of the camera.
ФЭД-4 camera operates on standard 35-mm film with a picture size of 24×36 mm. The wide range
of shutter speeds, the trigger winder, synchronizer, automatic releaser, dioptric view-finder setting, the
light weight and compactness of the camera will satisfy the requirements of either amateur or
professional photographer.
ФЭД-4 camera is fitted with “Industar-61”lens with lanthanum optics which makes it possible to
obtain perfect large-size pictures. The camera is so designed that it is also possible to use
interchangeable lenses “Jupiter-8”, “Jupiter-9”, “Jupiter-11”, “Jupiter-12”and others.
In taking a picture the camera is focused with the help of the range-finder.
The photoelectric exposure meter incorporated in the camera i makes it always possible to choose
the proper exposure and ensures obtaining good negatives under various lighting conditions.
The automatic releaser allows the photographer to take pictures of himself.
At the bottom of the camera there is a socket for a tripod.
It is possible to photograph with a tripod without taking the camera out of its case.

The camera can be loaded under ordinary soft
lighting conditions in the following way:
by turning the nut on the case bottom
unscrew the tripod screw retaining the camera;
remove the camera from the case. Raise the lock
shackles with the nail and turn them half-way
round as far as they go.
Then, pressing with the thumbs, shift the
camera back in such a way that its edge comes
out of the camera slot and remove it.
Take the take-up reel and the magazine out of
the camera. The reel is removed with a certain
amount of effort.
Load the magazine with a film (the magazine
is loaded in the darkness).
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.

Fit the take-up reel on the bush and then
place the magazine to the camera. At this point
the film should be slightly stretched and the
teeth of the sprocket should enter the
perforations of the film.
Close the camera.
The unexposed film is fed to the picture
aperture by winding the shutter twice pressing
the release button after each winding.
The winding lever should be turned as far as
it goes.
When properly loaded the camera is wound
easily without jerky motions and noticeable
efforts.
Then, by turning the dial scale set the “0”
point of the picture counter opposite to the
indicator.
Align the sensitivity scale dial with the film-
type indicator index in accordance with the data
of the film loaded in the camera.
The film indicator is a memory device
consisting of a movable sensitivity scale with
conventional designations of film types figured
on it.
—colour film for day light
—colour film for artificial light
—black-and-white film
and a stationary disk with an index.

The camera is equipped with “Industar-61”
lens with lanthanum optics.
The lens mount is fitted with the following
scales:
the diaphragm scale indicates changes of the
lens light diameter —rapidity of lens;
the depth-of-field scale which, when
focusing, indicates of the distance scale the
limits within which the range sharpness will be
satisfactory for each selected diaphragm value;
the distance scale serves for focusing the
lens. The scale designations correspond to the
distance from the object photographed to the
surface of the film in metres.
The camera is focused with the help of the
optical range-finder. In order to set the camera at
an accurate and proper focus first turn the ring
of the dioptric focusing, focus the view-finder
by your own sight (the dioptric focusing mecha-
nism provides a correction of ±2 diopters).
Then aim the camera at the object to be
photographed. In the center of the field of view
of the view-and-range-finder a disc differing in
colour is seen, in which the image will be
double.
By turning the distance ring of the lens align
the image into one. It is recommended to set the
camera approximately in the middle third of the
light field.

The camera exposure meter allows to quickly
and faithlessly find the exposure and diaphragm
values which are most favourable for taking
pictures under the given conditions.
The basic components of the exposure meter
are: a photocell, the galvanometer and a
calculator.
The necessary exposure is found with the
help of the calculator,
The calculator consists of three disks the first
of which represents a drive of fixing pointer and
has a shutter speed scale from 1/500 to 8 sec.
Black figures stand for parts of the second, red
ones —for whole seconds.
Dial 3is fitted with a diaphragm scale and a
scale of film sensitivity represented in GOST
units. The central stationary disk is equipped
with an indicator.
Nearby in the aperture the fixing pointer and
the galvanometer pointer are seen.
Prior to setting the necessary shutter speed
place the sensitivity value of the film loaded in
the camera on the scale opposite to the index.
Then aim the camera at the object to be
photographed and by turning the shutter speed
dial clockwise or counterclockwise make fixing
pointer 5coincide with galvanometer pointer 4
as it is shown in the Fig. Then find the reading
of the calculator which is at the point of
intersection of the strokes of the shutter speed
scale and that of the diaphragm scale within the
interval from 2.8 to 16.
It should be noticed that any of these
combinations gives the same exposure and is
used according to concrete photography
conditions. In the adjacent picture such
combinations are:
shutter speed 1/125 sec —diaphragm 2.8
correspondingly 1/60 —4; 1/30 —5.6; 1/15 —8;
1/8—11; ¼ —16.
It should be kept in mind that the exposure
meter is affected by the mean brightness of the
objects to be photographed. In case the area of
the object which is important from the point of
view of the plot occupies a small part of the
frame and its brightness considerably differs,
you should better find the exposure value
standing in the immediate vicinity of the object
to be photographed, i. e. at a distance of 30—40
cm.
Protect the aperture of the photoelectric
exposure meter from immediate rays of
powerful light sources, otherwise it may result

in an error in the process of determining the
exposure value.
In case the light source is in front of the
camera always use a sunshade!
In order to set the necessary exposure slightly
raise the head, turn it till the index coincides
with the division of the exposure scale and
lower the head back in place.
The exposure can be sei only with the shutter
wound up. Do not turn the head in the interval
between 30 end 1.
The numbers on the scale show the exposure
values provided automatically by the shutter (1,
½, ¼, 1/8, 1/15, l/30, 1/60, 1/125, 1/250, 1/500 sec). “B”
serves for obtaining prolonged exposures “by
hand”.
In order to wind the automatic releaser the
lever is turned counterclockwise from the
bottom position and into the top position. Then
press the release button of the automatic releaser
and stand in the spot selected beforehand. The
shutter will go off from 9 to 15 sec after the
automatic releaser is switched on.
It is possible to wind the shutter with the
automatic releaser either released or wound up.
A flashlamp can be used only at a l/30 sec
exposure.
When photographing with a lamp, place the
lamp reflector in the camera shoe and insert the
lamp plug pin wire in the synchronizer socket.
Irrespective of the set shutter speed the
diaphragm should be selected in accordance
with the sensitivity of the film, the distance to
the object photographed and the lamp power.
More detailed information on photographing
with flashlamps can be obtained by referring to
a manual on lamps and photography.
The following order of working with the
camera is recommended.
Open the case, remove the protective cover
from the lens. Looking into eye-piece of the
view-and-range-finder, select the spot to be
photographed and the desired arrangement of
image in the picture.
Focus the lens.
Set the diaphragm in accordance with the
required field depth.
Turning the lever, wind up the camera
shutter.
Using the calculator find the necessary
exposure value and set the shutter exposure head
opposite to the corresponding division value of
the scale.

Aim the camera at the object to be
photographed and smoothly and evenly press the
release button.
So you have exposed the whole film. Before
opening the camera the exposed film should be
rewound into the magazine.
For rewinding the film disengage the shutter
mechanism by pressing the fluted edge of the
disengaging bush downwards and turning the
bush towards letter “B”(return), whereupon the
disengaging bush should sink.
In the process of rewinding the film the lens
should be covered.
The rewinding head is turned in the direction
indicated by the arrow.
Complete rewind of the film is defined by the
effort needed for pulling out the film from the
take-up reel.
Open the camera and take out the magazine.
