HORIZON-205pc panoramic camera

This text is identical to the one in the Instruction manual, English version, 2003 year.

Attention!

Before using the Horizon-205pc panoramic camera one should study the rules of handling and the
order of operation according to the present instruction manual.

When having durable pauses in photographing don’t let the camera stay with the cocked shutter as

this may cause the operation deterioration.

Protect the viewfinder against shocks and mechanical damages.

The camera bought by you may differ a little from the one represented in the instruction manual due
to the fact that during manufacture of cameras their external appearance and operation qualities are
constantly improving.

Taking into account that the camera is a complicated device any repair and adjustment must be done
only at specialized workshop.

The present instruction manual shouldn’t be considered as a photography handbook.

1. General Information

1.1. Camera Purpose and its Advantages

The Horizon-205pc is the professional middle-sized photographic camera with a rotating non­interchangeable built-in lens. The camera is intended for different panoramic shooting: landscapes,
reports, interiors, architecture, etc.

It may be used successfully during the advertising and decorating practice, in scientific, technical
photography and other kinds of photographing by means of the roll film (of the 120-type).

The Horizon-205pc camera has the next advantages:

•

metallic focal shutter with the shutter speeds of 1, 1/2, 1/4, 1/8, 1/30 and 1/60 sec; the shutter
permits to take pictures within premises or in streets under the conditions of weak illumination;

•

the lens which rotates during operation provides the necessary quality of the image across the
whole field of the frame at the expense of elimination of the unevitable optical distortion which
takes place when shooting by other types of cameras and using wide angle lenses;

•

the optical viewfinder gives the possibility to define exactly the limits of the taken subject.
The right position of the camera, that is, “strictly along the horizon”, is controlled with the help
of the level which is visible in the viewfinder field of view;

•

THE ESSENTIAL ADVANTAGE OF THE HORIZON-205PC CAMERA IS ITS “SHIFT­MECHANISM” WHICH PERMITS MOVEMENT OF THE LENS UP AND DOWN ALONG
THE VERTICAL AT THE DISTANCE OF 7mm RELATIVELY THE CENTRAL ZERO
POINT; SUCH MOVEMENT CONSIDERABLY EXTENDS TECHNICAL POSSIBILITIES
OF PHOTOGRAPHING;

•

high quality prints of the large size may be made from the negatives which were produced by
the camera during taking pictures.

1.2. Instructions for Camera Handling

The camera is a precise optical and mechanical device.

Handle your camera with care, keep it clean, prevent from shocks, dust, moisture and sharp
temperature drop.

Horizon 205pc User manual, 2003 year

It is banned to touch optical details as this may cause damage of the coated surfaces. Wipe them
with a clean soft cloth or cotton wetted slightly by a rectified alcohol or ether.

If the camera was brought by you from cold outside into a warm room don’t take it up quickly from
the case. Otherwise its parts, especially optical ones, will bedew.

Keep the camera in a closed case.

Loading and unloading the camera is desirable to be done within the room or in the shadow so as to
prevent falling the direct sun rays or intensive artificial light. Cock the shutter against the stop.

When taking pictures in frosty weather don’t let the camera stay outward, take it out from the case
only during photographing.

5. Order of Camera Handling

5.1. Film Loading

The camera is loaded with the unperforated roll film of 60mm width (the type 120).

It’s not recommended to load the camera under direct light rays.
Load the camera by the film in the following order:
— set the frame counter 9 in the position “S” beforehand; in order

to reach it one should turn the knob for film transport “S” 3 until the
symbol “S” appears in the window of the frame counter.

If during this process the knob 3 is

fixed it is necessary to press the shutter
release button 20 every time;

— open the back cover 26 pressing

simultaneously the two keys of the lock

25 in the direction of the arrows;

— when pulling and holding

beforehand the knob 27 put the take-up spool in the right socket so that the
lever 22 and the spindle of the knob 27 enter into the recess of the spool.
Release the knob 27 and the take-up spool will be fixed;

— take the spool with the film (the type 120), unwrap it from the foil
and tear away the paper label from the end of the leader tape;

— let free the end of the film with the leader tape approximately for 10
cm. Put it under the guiding roller 14 and when pulling and holding the
knob 15 insert the supply spool with the film into the left socket so that the
spindle 18 and the spindle of the knob 15 insert the recesses of the spool.
Let the knob 15 free and the supply spool will be fixed;

— putting the end of the leader tape into the recess of the take-up spool,
wind it, rotating the knob for film transport 3 until the arrow on the leader
tape match the index 21 which is on the guides of the film channel. During
this process watch the tightness of winding the leader tape so as to prevent
its skewness, superimposing the leader tape on the end of the flange and
jamming its ends;

— close the back cover pressing it up to latching. When the back cover is closed the knobs 15 and

27 are blocked;

— in order to transport the unexposed film towards the frame window one should transport the film
(with the help of the knob 3) until the numeral “1” appears in the counter window with the preliminary
pressed knob for the shutter release.

There is the pocket for keepsakes of the film sensitivity on the back cover of the camera.

Put (into the pocket) the label of the film box with inscriptions about the film sensitivity.

5.2. Shutter Speed Setting

The shutter speed must be set only when the shutter has been
released.

First of all one should decide for himself what range is to be
operated in: “1–30–4” (1–1/30–1/4) or “2–60–8” (1/2–1/60–1/8).

Further by means of turning the lever 6 you must “open” the point
the colour of which corresponds to the colour of the chosen shutter
speed on the scale of the shutter speed range 11.

After that by turning the knob 5 set the pointer of the
corresponding colour 12 against the chosen shutter speed.

If the knob 5 isn’t fixed in the necessary position one should repeat
the above operation until reaching definite fixation. If necessary turn
the lever 2 for a small angle.

5.3. Diaphragm Setting

Preliminary one should cock the shutter by the lever 2 against the centre, the lens being accessible
now.

Through the viewing window of the lens turn the ring with the diaphragm scale 31 until the chosen
diaphragm matches with the index 30. Setting the diaphragm release the lever 2. After that will return
to its initial position the shutter under the action of the spring.

When defining the exposure time for obtaining the images of the higher quality we recommend you
to give preference to operation with the smaller diaphragm, that is to photography with the less
possible diaphragm and the more durable shutter speed.

5.4. Distance Setting

In dependance with the distance up to the subject being taken set through the lens viewing window
(providing the preliminary access towards the lens it was said in par. 5.3) the chosen value of distance
by turning the ring with the distance scale 29 until matching with the index 30. After setting the
distance release the lever 2 and due to this the shutter will return into its initial position under the
action of the spring.

5.5. Photographing

Cock the shutter by turning the shutter cocking lever 2 counterclockwise
against the stop.

It is desirable to use the tripod when taking pictures.

Focus the camera at the subject being taken and looking into the
eyepiece of the viewfinder define the limits of this subject.

The level 10 controls the horizontal position of the camera during
photographing.

If the camera is in the right position the bubble of the level 10 must be in
the center of the light circle which is seen in the viewfinder field of view.

Horizon 205pc User manual, 2003 year

When taking pictures in the vertical position of the camera one should use the level of the tripod.

Having done the preliminary preparatory operations press the shutter release button and take
pictures.

Remember that abrupt pressing the shutter release button will cause the inevitable camera moving at
the moment of exposure and blurring of the picture.

The “shift”-mechanism available in the camera permits to move the lens along the scale 7 up and
down up to 7 mm relatively the center of the setting point by means of rotating the knob 8 to the left or
to the right, correspondingly, this expanding considerably technical possibilities of photographing.

5.6. Unloading Camera

After the frame counter counts 6 frames the camera must be unloaded by means of winding the rest
of the paper leader tape at the take-up spool, the shutter release button 20 being pressed preliminary.
During this operation the symbol “S” must appear in the window of the frame counter 9.

Having finished winding (the force applied the knob decreases) open the back cover 26 squeezing
two keys of the lock 25, pull the knob of the take-up spool 27 and take out the spool with the exposed
film.

5.7. Light Filters

5.7.1. Operational Properties of Light Filters

The ND-2x, UV-1x, YG-2x and R-8x light filters which are included in the complete set of the
camera differ from each other by their operational properties.

ND-2x: the neutral density light filter used for getting pictures of the normal density at excessive
illumination.

UV-1x: the colourless ultra-violet light filter used for UV rays, for example when taking pictures
high in the mountains on the black-and-white and colour films.

YG-2x: the yellow-green light filter used for correction of the tonal rendering. It is especially good
for correct rendering the relations between the visual brightness of the coloured subjects; in particular
red and green tones, for example when making portraiture both with day and artificial light, during art
and technical photographing canvases, colour drawings.

R-8x: the red light filter used for elimination of influence of the atmospheric haze and creation of
special effects, for example, during day photographing it permits to get “the night landscape”, during
back lighting photographing it is possible to get “the moon light”. As for usual photographing it is not
used as it distorts notably the relations of the visual brightness of the subject.

5.7.2. Mounting Light Filters

Turning the cocking lever 2 up to the center and holding
it by a hand insert (through the viewing window of the
lens) the mount of the chosen light filter into the slots on
the lens mount up to its fixation.

Having attached the light filter release the lever 2 and
then the shutter will return into its initial position.
