1. PEEFACE
LC-A (LOMO COMPACT-AUTOMAT) is a miniature scale camera with telescopic viewfinder and
automatic program exposure working. The camera operates in temperature range from minus 15
to +45° C, direct solar radiation and precipitation excluded.
The camera is powered from a d. c. source, type LR-44 (CII.O.18-Y2), 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.
Camera LC-A has some distinctive features. It is so small that you can carry it in your pocket or in a
handbag. 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 contaminations in storage.
The camera is provided with electromechanical program shutter controlled with electronic
exposure meter ensuring automatic working of exposures.

Camera viewfinder is telescopic. A luminous picture limiting frame with a parallax mark for taking
at near distances, a light indicator for control over power cells energetic level, a light indicator
warning of expected shutter speeds longer than 1/30 s are in the field of vision of the view-finder.
A wide-angle high power objective «Minitar»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.
Focusing is carried out by the distance scale and by symbols Visible in the viewfinder field of vision.
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.
Contact «X», is used for synchronization of the shutter with the flash bulb.

Film advance and shutter cocking are carried out simultaneously by means of a hand wheel with
360° rotation angle. Frame counter counts number of frames taken, and it is set to Initial position
automatically as soon a s the camera back is opened.
Re wind crank is of a tape-measure type. For rewinding film advance gear disengagement knob is
to be fixed in the depressed position.
Provision is made in the camera for a special motor attachment for automatic film transport.
