1. Photographic Camera
The wide-known family of “Zorki” cameras has been refilled with a new model — “Zorki-10” camera.
Unlike its earlier models, the “Zorki-10” camera is a fully automatic camera with automatic exposure
settings. This considerably simplifies the shooting process. The fact that the range-finder is coupled
with the viewfinder allows to make fast focusing. Between the lens diaphragm shutter with adder-
mechanism automatically sets diaphragm and exposure time depending on the set film sensitivity and
brightness of the object to be photographed. Before proceeding to take pictures, thoroughly study the
operation of the camera and its handling instructions presented in this Manual.
Remember, that the automatic setting lever should always be set against the index “A”, except cases
when photographing with exposure time “B”. Set the self-timer lever only after the shutter is cocked.
Always press the shutter release key until it goes.
2. Specification of the camera
The “Zorki-10” camera has fully automatic exposure settings and is designed for using the 35-mm
perforated film having 24x36 mm picture sizes. The camera is fitted with a high-precision “Industar-
63” lens, which is built-in in the between the lens diaphragm shutter.
Focal length of the lens — 45 mm
Relative aperture — 1:2,8
Angular field — 50°
The lens is focussed by moving the whole of the unit with the aid of a focusing ring. The camera is
equipped with a rangefinder (base 38 mm and viewfinder magnification 0,65
x
).
The optical viewfinder and the rangefinder are coupled in one window. The collimator viewfinder
has fluorescent frames, limiting the field of view. To eliminate parallax while photographing at a
distance of 1,5 m (5 ft.) there is an additional frame, shifted to the right and downwards. To signalize
of insufficient illumination of the object to be photographed there is a red line in the viewfinder field
of view on which the exposure meter pointer, seen in the field of view, stays.
The camera has a FZA-18 diaphragm shutter with exposure speeds from 1/30 to 1/500 sec and “B”
exposure. The exposure speeds smoothly change over the whole range.
The shutter is provided with a self-timer and a contact to switch on electronic flashes. The self-
timer operates not earlier than 8—15 seconds after the key has been pressed. The shutter is released by
a shutter release key. When the release key is pressed, desired exposure time and diaphragm are set,
according to set film sensitivity.
The camera has a device, which switches off automation and allows handle diaphragming from
1:2,8 to 1:22. In this case the exposure time does not change and equals 1/30 sec.
The sensitivity range of the used films equals from 20 to 320 ASA units and from 14 to 26 DIN
grades.
Camera shutter cocking, film transporting and setting the exposure counter take place
simultaneously when turning the lever until it goes.
The exposure counter shows the number of unexposed frames and returns to initial position while
opening the back cover.
The camera is loaded with standard cassette for 36 frames. Film capacity of the cassette is 1,65 m.
M52x0,75 thread on the lens is provided for mounting filters.

ZORKI-10 User manual, 1965 year

Light passing throught filter gets not only into the lens but — on the circular electric eye window,
which surrounds the lens. Therefore the correction for filter factor is practically not needed.
The camera has a tripod screw-in bushing with 3/8” standard thread intended for mounting the
camera on the tripod.
The camera is provided with an accessory shoe for attaching the flash lamp.
The camera has a convenient leather case. You can take hand-held pictures without taking the
camera out of the case. Overall dimensions of the camera (without case) with a lens — not more than
129x77x76 mm
Weight of the camera without case — not more than 750 g
The “Zorki-10” camera is designed for versatile amateur photography, for photographing
architectural ensembles, landscapes, portraits etc.

.
Set the film sensitivity, rotating the film sensitivity ring
until necessary number of ASA units or DIN grades appears
in the window (Fig. 11).
Fig. 10

.
Set the automatic setting lever 13 (Fig. 3) at “A”
or
“Automatic” (Fig. 10).
It is possible to take pictures with the “Zorki-10”
camera
without diaphragm and exposure time presetting. Point the
camera at the subject to be taken. Observing the object,
bring it to the center of the bright-
line frame and pressing
gently (without jerking) shutter release
key until it goes,
release the shutter.
6. Taking the Picture
When the light levels are not suitable for photography the
viewfinder needle appears in the zone of red-
colored line (Fig. 12).
To photograph at this light change the film for one with hi
gher
sensitivity, or work with flash-lamp or with “B” time exposure.

When taking a photograph at ar
ound 1.5 m (5 ft.) use the inside
markings just inside the bright-
line frame (small frame) (Fig. 13),
and at other distances use the outside markings (large frame).
To take photographs automatically set the automatic setting
lever at “A”.
The mec
hanism of automatic exposure setting is so designed
that, when changing the brightness of the object to be
photographed, the exposure time and the diaphragm are
simultaneously changing according to the set film sensitivity.
At bright light after the s
hutter release key is pressed the short
exposure time and small aperture are set automatically, and in
subdued light, on the contrary, the longer exposure time and larger
aperture are set.
Fig. 13
In the viewfinder we see the exposure meter needle, which
moves from left to right when the light grows higher. There is a
triangular mark at the top of the viewfind
er. Observing the position
of the needle relative to the triangle it is possible to determine the
set exposure time. Interval of the needle between the right end of
the red line and the triangle corresponds to exposure times from
1/30 to 1/200 sec (Fig. 14). Fig. 14
If the needle is positioned to the right of the triangle, the shutter
sets automatically the exp
osure times in the range from 1/200 and
less (Fig. 15).
Fig. 15
Construction of the “Zorki-10” camera enab
les setting the lens
opening from 1:2,
8 to 1:22 for photographing without automation.
To do this move the automatic setting lever from “A”
to desired
lens opening. The shutter exposure time will be equal to 1/30 sec.
To obtain slower shutter speeds (hand-c
ontrolled exposure) the
lever of hand-controlled time exposure should be set at “B”
(Fig.
16). When doing this, it is possible to change the le
ns opening
from 1:2,8 to 1:22.
When you want to operate with automatic shutter speeds after
hand-controlled ones, set the automatic setting lever at “A”
. In this
case the lever of hand-
controlled shutter speeds will return to its
initial position.
Fig. 16
7. Focusing the Lens
Focus the lens by turning the focusing ring 8 (Fig. 2).
In this case two images of the subject to photograph
observed in the finder wil
l shift relative to each
other.
The focussing will be cor
rect, when the two
images are exactly matched into one.

8. Photographing with self-timer
Engage the self-timer m
echanism only after the shutter is cocked. To take
pictures with the self-timer set the lever 4 (Fig. 1) against letter “V”
(Fig.
17) and press the release key. In 8—15 seconds the shutter will operate.
When taking sequence pictures with the self-time
r, each time set the
self-timer lever against the letter “V”.
With exposure time “B” the self-timer does not operate.
Note. When pressing the release key, do not shade the circular electric
eye window from getting the light, which is reflected by
the object to be
photographed. At the same time do not shade the light illuminating the
object, taking into account that the exposure is set automatically and
corresponds to the illumination of the object by the light which is reflected
by the photographed object at the moment of pressing the release key.
If the brightness of the photographed object at the time (8—
15 sec) of
self-
timer operation changes, the exposure time, set by the automatic
mechanism of the camera at the moment of pressing the key,
will not
correspond to the brightness of the photographed object at the moment
when the shutter comes into action.
Fig. 17
9. Photographing with Flash Lamps
In insufficient light when the needle is within the red line zone of
the viewfinder as well as in other necessary cases, take pictures
with flash lamps.
In this case mount the flash lamp on the accessory
shoe 1 of the
camera and insert the plug of the flash lamp
into the connector 2
(Fig. 1).
Switching on the flash lamp, disengage the automa
tion and set
desired diaphragm.
If the self-timer lever is set against letter “X”
you can take
pictures only with electronic flash lamps.
10. Unloading the Camera
To rewind the exposed film, press button 15 (Fig. 3)
and having raised, by turning, the film rewind crank
rotate it clockwise (Fig. 18).
When the film is completely rewound loose the
rewind release button and open the back cover.
Before removing the cassette with exposed film,
pull out the film rewind head as far as it will go.
Unload the camera in subdued light or in shade.

11. Care of the Camera
1. Keep the camera clean and handle it with great care. Protect it from mechanical shocks and damages
as well as against moisture and sharp temperature fluctuations.
2. The lens is the heart of the camera therefore it requires the best care. Wipe off the optical coated
surfaces only on the outside using for this purpose fatless soft brush or clean soft fatless cloth or cotton
wool. Slightly moisten the cloth or cotton wool with alcohol and wring out to avoid traces of liquid.
3. If the camera is suddenly brought into a warm room from a cold place do not open the case and do
not uncover the optics for 1—1,5 hours to avoid clouding up. When photographing in wet weather
thoroughly wipe the camera.
4. Keep the camera in a closed case. The shutter should be released. Do not disassemble the camera.
When the camera is out of order apply to a special repair shop.
Note to “Taking the picture”
When there is considerable contrast between the brightness cf the background and the object to
be photographed, correction should be introduced on account of setting the film sensitivity with the
aid of the film sensitivity setting ring (Fig. 2). For example:
1. The main object of photographing is less bright than the surrounding background. Such a case
usually occurs when taking pictures against snow, sky or water background. If to take a picture
without correction, the main object (for example, a face of a man) will be underexposed and all the
light surrounding objects will be correctly reproduced.
To obtain the correct exposure of the main (dark) object of photographing set smaller value of
the film sensitivity as compared with practically used one.
In this case good results are usually obtained when sensitivity decreases on one step of the
sensitivity scale. For example, when photographing on the film of 80 ASA unils sensitivity, set 40
ASA units on the scale.
If the film sensitivity is given in DIN grades, then, for instance, 17 DIN grades should be set on
the scale instead of the used film of 20 DIN grades.
2. The main object of photographing is brighter than the surrounding background, for instance,
when photographing an illuminated face of a person against the dark background. When
photographing without correction, this picture of a person's face will be overexposed. In this case
for obtaining the correct exposure of the main object set the larger film sensitivity as compared with
the sensitivity of the film used. In practice there can be stronger contrasts, then the correct exposure
of the main object is correspondingly obtained by other corrections.
