CAMERA LUBITEL I66 B"

ATTENTION

Camera Lubitel 166B is rated for work in temperature range from minus 15 to +45 degrees C, without direct
effect of solar radiation and atmospheric precipitation.




1. GENERAL INSTRUCTIONS

LUBITEL 166B is an up-to-date and simple in operation camera intended for the widest range of amateurs

The camera incorporates a coated lens, two viewfinders (optical and frame one), diaphragm shutter with wide
range of speeds, self-timer and flash synchronizer. It assures precise focusing, daylight film changing and
exterior shooting on tripod and hand-held shooting.

It is enough to raise a little reflex viewfinder cover to see deep between the light protective hoods large and for
any illumination distinct clear image according to which it is easy to fit frame limits when the object is already
found or to find a new scene.

Image focusing is performed by slight rotation of a lens knurled mount.

Scales of distances, diaphragms and exposures and all the control units are located to assure speed and
convenient operation.

Frame counting is performed through the window according to values on light protective paper of the film.

Due to reflex viewfinder it is possible to take pictures at high level holding the camera over the head as well as
turning it horizontally at the right angle. Viewfinder lens has f/2.8, i. e. considerably higher than the
photographic lens and thus the higher sensitivity to focusing.

For taking pictures at eye level (shots have then more natural perspective) the frame viewfinder is used that is
more convenient when there is experience in estimating distances by eye and in correct focusing according to
distance scale.

It is daylight loaded camera. For convenience the back is hinged.

The reflex viewfinder consists of the viewfinder itself and a ground glass representing a small circle in the
center of field lens with a folding focusing magnifier mounted above it. The viewfinder is provided with metal
light protective hoods that open simultaneously with raising the cover. The viewfinder should be closed by the
following procedures: first close the magnifier, then the side hoods, the rear hood with a square window and at
last the cover until its front frame lug catches with the viewfinder case lock catch.

Focusing the images on the ground glass circle and in film plane is performed simultaneously as both lenses are
coupled with each other with knurled mounts.

The focusing magnifier is attached to the panel from inside. The magnifier is set to operation by pulling it up
from the cover.

The frame viewfinder is formed by the front frame and rear light protective hood with a square window. To
open the viewfinder it is necessary to tilt the panel inside so that it catches the rear hood lug. Slightly pulling out
the rear hood is enough to close the viewfinder.

To determine frame limits the camera should be held at eye level, the object should be observed through the
square window in the Tear hood keeping the camera at the distance when the window edges coincide with those
of the square opening in front frame. In this case the limits of the viewfinder field will be the frame limits.

The distance scale is graduated at viewfinder lens mount in meters.

Diaphragm shutter is automatically giving the following speeds: 1/250, 1/125, 1/60, 1130, 1/15 s. With shutter
set to B
any manual-control shutter speeds are obtainable. Selected exposure time is set by rotating the adjusting ring
lever 5
(fig. 2) to coincide the ring edge index with required exposure value (mean exposure is not obtainable with
index intermediate positions).

Before shooting it is necessary to wind the shutter-rotating the winding lever fully downward. Shutter is
released with smooth
pressing the release lever or the cable release the camera is provided with the socket for it. With shutter set to B
index
it remains opened from the moment of pressing the release lever to its releasing.

To activate the self-timer it is necessary to set the selected automatic exposure, wind the shutter, turn the self-
timer lever 6 (fig. 1) fully downward and to press the release lever 5 (fig. 2). In 7--12 seconds the shutter will
operate and the picture will be taken.

Remember that with shutter set to B and release lever pressed it is impossible to wind the self-timer lever.

Flash synchronizer is intended for matching the flashing moment with complete shutter opening.

With electronic flash used the shutter may be set to any automatic exposure. With flash bulb used the shutter
should be set to 1/15 or B. On releasing the shutter the synchronizer will act automatically.

                                              5.1. Loading the Camera

Taking the camera in your left hand, open the camera back pulling off preliminarily the lock spring.

Turning the film rewinding knob 21 (fig. 2), bring the spool slot at position convenient for loading the film
protective paper end.

Fully pull off the both heads of the supply spool spindles. Break the seal of the film protective paper and insert
the spool with the film into the body receptacle between the spring and the body wall having pressed the flat
spring with your finger. Pressing the supply spool with your finger insert to it both spindles by pressing their
heads.

Unwind the end of the protective paper and on folding it down for about 10 mm insert in the slot of the take-up
spool. Then holding the spool with the film with your left finger and rotating the film rewinding knob wind 2--3
layers of the protective paper to the take-up spool. Close the camera back assured that the paper tension is good.

Having turned anticlockwise the window cover plate head 30 (fig. 5) rotate the film rewinding knob 21 (fig. 2)
until first the signal marks on protective paper and then c1~ appear in the window. Close the cover plate.

                                                 5.2. Taking Pictures

Before taking pictures, set the required exposure time and diaphragm. Exposure is set on exposure scale by
rotating exposure adjusting ring dog 5 (fig. 2). The required diaphragm value is set by moving the lever 22 (fig.
3) with index along the scale.

Looking to the viewfinder determine the frame limits and with the focusing reach the required sharpness at the
ground glass circle. If the object image that is required to get most sharp should be located at the picture edge
turn the camera while focusing so that the object image was in the center find prior to the shutter release return
the camera to the initial position.

With the winding lever I7 (fig. 2) wind the shutter and release it smoothly.

Pull the film at a frame length (immediately after taking picture not to forget). To do that open the window
cover plate and rotate the film rewinding knob 21 till the following figure appears in the window, then close the
cover plate.


                                             5.3. Unloading the Camera

After the twelfth exposure has been made rewind at the take-up spool the film protective paper. Sometimes
when the winding is almost completed the turning of the knob is detained due to the paper jammed in the supply
spool slit. However this should not prevent the daylight unloading the camera.

Open the camera back.

Fully pull off the film rewinding knob and take-up spool head.

Carefully take but the spool with the exposed film, seal the protective paper end and keep the film until it is
developed.

Having pulled off the heads of the supply spool spindles as far as they will go, take the spool out of its
receptacle and insert into that of the take-up spool. Further slightly turning the film rewinding knob, press it and
the head of the take-up spool spindle up to the stop.

Close the camera back.


                                                 6. MAINTENANCE

Handle the camera with care.

Contaminated lenses deteriorate pictures sharpness, so it is necessary to keep lenses always clean. The objective
lenses could be wiped from the outside only using a clean cambric or linen cloth or cotton wool, on having
breathed on them.

Never disassemble the camera.

Never wipe the plastic parts of the camera and the field lens with alcohol, acetone and other active solvents.
