English manual for LOMO LC-A camera
OPERATION MANUAL
LOMO COMPACT AUTOMAT camera is designed for operation in
temperature range from minus 15 to +45 °C, direct solar radiation and
precipitation excluded.
Camera LC-A has some distinctive features. It is so small that you can carry it
in your pocket. Automatic exposure working is ensured in a wide range of object
brightness. The camera is provided with a device protecting the photo objective
and viewfinder objective from mechanical damages and contamination in storage.
The camera is powered from a D.C. source, type SR-44, S-76.
NOTE - When using another power source with temperature operation range
lower than that of your camera, the camera temperature operation range is to be
limited with that of the power source.
A light indicator for control over power cells level and a light indicator
warning of expected shutter speeds longer than 1/30 s are in the field of vision
of the viewfinder.
A wide-angle high power objective is rigidly built in the camera, which
considerably extends opportunities of the camera (photographing of architectural
subjects and landscapes at short distances, photographing of landscapes in small
premises and so on). In this case, some vignetting (decrease of brightness and
definition towards the margin of the field) is possible that is admissible for a
camera of this type.
Focusing is performed by the distance scale.
For photographing with a flash bulb, a manual diaphragm setting in the range of
2.8 to 16 is provided. At switching-over from automatic operation ("A") to
manual diaphragm setting, a shutter speed 1/60 s is set.

5. PRE-STARTING PROCEDURE
5.1. Installing and checking the cells
To install the power source into the camera, move cover 16
(Fig. 4) in a direction pointed with the arrow. Put the cells into the container
so that sign "+" on the cells is looking towards sign "+" on the camera
container. Meanwhile the flexible tape serving for removing the power source
must be under the power source and its end must jut out.
Close the container cover. The cells installed check them for serviceability.
For this aim, move curtains control key 14 and open the objective and the
viewfinder. Looking through the inspection window 21 (Fig. 5) of the viewfinder
press down the release knob 10 (Fig.2) until it is stopped slightly.
If the cells are serviceable and inserted in a correct way, a red color
indicator should shine at the upper left corner of the viewfinder. If the
indicator does not shine check up whether the cells are inserted in a correct
way and contact areas are clean. If the indicator does not yet shine replace all
the cells.
Checking up energetic level of power cells during taking pictures is made
according to the indicator (shines or does not shine) on pressing down the
release knob.
5.2. Camera loading
|
To insert the cassette with film into the camera,
swing out knob 23 (Fig.5) of handwheel 22 and pulling it upward until
stop, open the camera back 30. Insert the cassette into receptacle 25 so
that a film leader is facing to the right. Lower handwheel 22 so that
yoke 24 enters the cassette spool plug.
Put the film leader (Fig.6) into the slot of the take-out spool so that
film perforation engages into mesh with a tooth of take-up spool 28
(Fig.5). Holding the cassette with film by your hand and rotating
handwheel 20 with the other hand, take up film slack. Make sure the film
is positioned between limiters 26 that it is engaged with gear 27 and is
fixed reliably at take-up spool 28.
If handwheel 20 has turned up to stop while the film slack has not yet
taken up, press down release knob 10 (Fig.2) and continue taking up the
slack. |
 |
ATTENTION! If the objective and viewfinder are covered
with the guard curtains, release knob 10 is interlocked. To unlock it, use key
14 (Fig.4) to open protective curtains of the taking objective.
After the slack is taken up close camera back 30 (Fig.5) and press it slightly
to the body so that the back is fixed.
Turn handwheel 20 against the stop and press the release knob. Repeat this
procedure twice or thrice till digit "1" appears in the frame counter window
against the index. While pulling the film, pay your attention to rewind
handwheel 22 (Fig.5). If the camera is loaded with the film correctly, handwheel
22 should rotate also on rotation of handwheel 20.
5.3. Setting value of film light sensitivity
After installing the cassette with film into the camera, it
is required to introduce into the exposure meter a value of light sensitivity of
film applied (the value given on the package). For this aim rotate film light
sensitivity setting knob 6 (Fig.2) till a value required appears in window 7.
Loading the camera with a new film, it is required to introduce a new value of
light sensitivity.
The light sensitivity scale in the camera has numberings 25, 50, 100, 200, 400
ASA/ISO.
5.4. Focusing
Objective in LC-A camera is focused by distance scale.
To focus by distance scale, estimate camera-to-object distance and bring key 8
(Fig. 2) to the corresponding position with respect to the distance scale.
6. PHOTOGRAPHY
6.1. Automatic photography
Draw apart curtains 2 (Fig.2) covering objective 3 and
viewfinder 5.
Bring diaphragm setting key 9 to position "A".
Look at window 7 to check up whether film sensitivity value is set correctly.
Check up for serviceability of the power source slightly pressing down release
knob 10 (Fig.2) and watching the indicator in viewfinder inspection window 21.
Focus the objective and find subject borders by means of the picture-limiting
frame.
Check to see that you have not shut with your fingers light-limiting device 4
and objective 3.
Press release knob 10 until stop. Release the knob only after shutter responded.
6.2. Photography with a flash bulb
With slight pressing of the release knob, you can see in the
viewfinder a red-color indicator at the upper right corner simultaneously with
the red-color indicator at the upper left corner. Its luminescence is a witness
of an exposure times longer that 1/30 s.
In this case in order to avoid somewhat blurred image on the film it is
necessary to ensure steadiness of the camera, i.e. photography from a support,
from a tripod or to use a flash bulb.
Camera design is intended for use of the flash bulb with cable-free connection.
Operation mode of the camera with the flash bulb differs from automatic
operation only by determination of diaphragm value and input of this data into
the camera mechanism. Shutter speed of 1/60 s is set automatically when
diaphragm values from 2.8 to 16 are set.
To determine diaphragm value, divide the flash bulb guide number by an object
distance value in meters.
Put key 9 (Fig.2) against the calculated diaphragm value and bring key 8 to a
corresponding position with respect to distance scale. The camera is prepared
for photography.
7. FRAME COUNTER
The frame counter operates on the addition principle and
shows number of frames taken. It is advisable to take the first picture when
counter digit" 1" is against the index. Numbers " 12", "24", "36" and the
initial point on the frame counter scale are marked yellow.
With the camera back open, the frame counter is set to initial position
automatically.
8. FILM ADVANCE AND TAKING OUT
Cocking of the shutter and advance of the film are effected
in the camera simultaneously, with complete revolution of handwheel 20 (Fig. 5).
Sometimes however, the complete revolution of handwheel 20 is impossible because
the film end is lacking for a full frame. Do not force the handwheel in this
case, otherwise the film can break loose from the spool core.
To rewind the film to the cassette, press the film advance gear disengagement
knob 15 (Fig.4). Hinge away knob 23 (Fig.5) and turn it in the direction pointed
with the arrow. Rewind over, you will feel a slight jerk of the film and an
easier run of handwheel 22.
Pull handwheel 22 upward taking hold on knob 23. At the end of handwheel run,
when the camera back is opened, take out the cassette with the film.
Now the camera is prepared for subsequent loading with film.
9. OPERATIONS INSTRUCTIONS
In order the camera to be always serviceable and to make high
quality pictures, you should:
- Protect the camera against shocks and jerks in order to avoid damage of
precise mechanical and electronic systems;
- Protect the camera against humidity and dust;
- Do not allow heating of the camera, never leave in the sun, on the hot sand,
etc. As it can cause damage of the film, power source or electronic system and
lead thus to a wrong exposure;
- Pay attention to the cleanness of lenses as their contamination deteriorates
quality of film image.
Never disassemble the camera.
Only skilled experts of repair shops can eliminate damages.
For long-term storage, the shutter should not be cocked. Take
power source cells out of their container also. The guard curtains should close
the objective and the viewfinder.
Never wipe non-metal parts of the camera with alcohol, acetone, petrol and other
active solvents.
