1. General notes
1.1. Purpose and Features
Horizon-202 is a special camera with a fixed built-in lens intended for taking various panorama
pictures: reportings, landscapes, interiors, sports events, fashion, tourism, arcuitecture, etc., both by the
amateur and professional photographers. It can be used to take various pictures on black-and-white and
color films.
Features of the HORIZON-202 camera:
—Shutter cocking lever with locking against half- and
double-cocking and quite small angle of cocking (210°) for
the given frame size makes for fast picture taking and
improves camera performance.
—Metallic focal shutter with shutter speeds from 1/2 to
1/250 s

enables to shoot in various conditions (indoors or
outdoors at poor lighting); low temperatures (up to –15°C)
practically do not impair shutter operation.
—Rotating lens, when shooting, ensures the necessary
image quality all over the frame area due to eliminating of the
invenitable optical distortion which occurs when taking
pictures with wide-angle lenses.
—Frame counter, automatically re-setting to the inital
position when reloading the film, releases the amateur from
setting the counter to “0” manually.
—Optical viewfinder enables to determine the exact limits
of the object to be photographed. Correct camera position
(strictly horizontal) is controlled by the level seen in the
viewfinder field of view.
—Film rewind crank and shutter disengaging button of stay-put type cut down the time necessary
for preparation of the camera for shooting.
—Back door lock is interlocked with the film rewind crank which makes for simplified and fast
film reloading.
1.2. Handling Rules
The camera is a precise optical-mechanical instrument. It should be handled carefully, kept clean
and protected from jolts, dust, moisture and sharp temperature fluctuation.
Do not remove the camera from its case the moment it is brought indoors from cold to avoid
sweating of its parts, especially optical ones.
Do not touch the surfaces of the optical parts with fingers since it may damage their coatings. Clean

There were a few cameras variants with a different shutter speeds numbers, from 6 up to 8.

the coated optical surfaces with a clean soft cloth or cotton wool wad slightly moistened with rectified
alcohol or ether.
Keep the camera closed in its case. Load and unload the camera indoors or in shade protecting it
against direct sun light or bright artifical illumination. Always wind the shutter as far as it will go.
When taking pictures in frosty weather, it is better to keep the camera under your street-clothes and
take it out only for the time of shooting.

4. Operating procedure
4.1. Loading the Camera
The camera accepts standard cassettes loaded with any type of 35mm film. If you load the cassette
with film on your own, be sure to properly secure the film end in the cassette spool to prevent it
breaking away from the spool during operation. See to it that the film leader is free from bends and
folds and cut to the standard form.
The camera loading should not be done in direct sun light.
Load the camera in the folowing way:
—Flip open film rewind crank 8 and holding it, pull out rewind
knob 5 as far as it will go. Holding the film rewind knob in this
position, open back door 20 with your second hand.

—Carefuly insert the film leader under guiding roller 15 and draw out
the film by about 12–15cm.
—Put a loaded cassette into socket 13 pulling out the rewind knob as
far as it will go.
—Return the film rewind knob completely home slightly turning it to
let spool guide 14 enter the cassette.
—Pass the film leader under sprocket 18 so that it appears from under
take-up spool 19. To make this process easier rotate the sprocket with your
fingers with button 21 pressed down.
—Insert the film leader into the slot of the take-up spool and draw the
film back on to the film gate. Make sure that the sprocket tooth engage a film
perforation hole. Reel the appear loop on the take-up spool rotating shutter
cocking lever 2. The film should be paced on film channel guides 16 without
skewing.
—Close the back door 20 tightly pressing it to make the lock latch. Cock
and fire the shutter.
—To transport a nonexposed portion of film to the film gate, cock and
fire the shutter once again. When cocking the shutter for the second time the
frame counter should be set at “1”, the latter being positioned approximately
in the center of exposure counter window 12. Now you are ready to shoot.
The shutter is cocked by turning smoothly lever 2 counter-clockwise to its
fullest extent and released by pressing release button 11. Should the film be
wound tightly in the cassette, the film rewind knob will rotate when the shutter is being cocked.
If the film is loose in the cassette, the rewind knob will fail to rotate at the first frames.
Automatic frame counter shows the number of the frame being positioned against the film gate.
Put the film box label with film speed indicated on it, into film check pocket 24.
4.2. Operating Mode Setting
4.2.1. Shutter Speed Setting
Turn operating mode selection switch 7 to set the required shutter speed range from 2 to 15 or 30 to
250. Set lever 9 against the required shutter speed value.
Each position of the lever is click-stopped.
4.2.2. Aperture setting
Set aperture setting lever 10 opposite to the required aperture value. Each position of the lever is
click-stopped.
At exposure determining to obtain pictures of higher quality the aperture should be smaller and
shutter speed longer. Shutter speed and aperture should be set only with the shutter cocked.
4.2.3. Depth of field of the lens
The OF-28P fixed built-in lens has no distance scale.
To determine the depth of field, make use of the table set forth below. For example, with aperture
set at 8, the depth of field will be from 2m to unfinity.

4.2.4. Depth of Field Table for the HORIZON-202 Camera Lens
Aperture
Depth of field, m
2,8 5,5–∞
4 3,9–∞
5,6 2,9–∞
8 2–∞
11 1,5–∞
16 1–∞
4.3. Picture Taking
Cock the shutter.
When shooting hold the camera in the way
shown in the picture.
Be sure that the frame is not blocked by your
fingers.
Aim the camera at the object to be photographed
and looking through the viewfinder determine its
limits.
Camera horizontal portion is adjusted by lever 3.
At correct camera position which prevents a
perspectively distorted picture, the level ball
should be in the center of the light circle seen in
the viewfinder field of view.
For vertical shorts no level is used. Having prepare the camera for shooting press the release button
as far as it will go to take a picture.
REMEMBER, that sharp pressing on the release button results in camera shake at the moment of
exposure and thus in blur of the picture.
To take picture with longer exposures than 1/30s the shutter is better released with the help of a
cable release which is screwed into the release button socket.
You can as well make use of a tripod having removed the handle beforehand.
4.5. Mounting the Handle
Take the handle out of the case. Remove the end-cap 23 from the camera locating hole. To do this
take a pressure on the end-cap with your thumb and turn it in either sides till it comes out of the
camera.
Put the handle in the hole and pressing it to the camera turn it in either direction to a click-stop.
At correct mounting of the handle the key down should be on the outer side of the camera. To
remove the handle from the camers press the key down to a stop and turn the handle till it comes out of
the camera.

4.6. Camera Unloading
When the exposure counter shows figure 22, the film should be rewound back into the cassette and
the camera unloaded. To do this:
—Press button 21 on the camera bottom.
—Flip open crank 8 and rotate it in the arrow direction till the film leader leaves the take-up spool.
Try to rotate the crank smoothly, without jerks and not too fast to avoid traces of static electricity on
film.
—Pull film rewind knob 5 all the way out; open the back door. Remove the cassette, holding the
film rewind knob.
If necessary, the camera can be unloaded after exposing any number of frames, having rewound the
film into the cassette beforehand.
4.7. Mounting the Light Filters
Mount the light filter on the camera. To do this, with the help of the
shutter cocking lever, align the lens axis with the film gate center in
body. Through the cylindrical cup window put the light filter mount into
the lens body socket. In so doing, press the light filter spring and put it
behind the cup window (see the diagram).
To remove the light filter, take the second one delivered with camera,
and coupling the hooks, slightly draw the light filter in the direction
indicated by an arrow in the above mentioned diaphragm.
