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.

FED 4 User Manual

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

FED 4 User Manual

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.

FED 4 User Manual

–8 –

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.
