ZENIT-122 is a 35-mm single lens reflex camera intended for taking various
amateur pictures on black-and-white and color films. It can be used for special
kinds of photography as well, such as copying, taking close-up pictures of small-
size objects at short distances (ultra-close-up photography), taking pictures with
the help of a microscope (photomicrography), etc.
The- camera accepts interchangeable lenses with M42Xl screw fittings and
mechanical back focai distance of 45.5 mm.
The following features are remarkable with the camera:
- semi-automatic exposure meter operating through the lens (TTL system) pro-
vides for correct exposure setting when taking pictures with the standard lens as
well as with interchangeable lenses, light filters, supplementary lenses, extension
tubes;
'- light-emitting diodes in the viewfinder, indicating correct exposure setting,
can be clearly seen both with the diaphragm fully open and stoqped down;
- instant return mirror ensures continuous viewing of a' subject before and
after exposure;
- high speed lens is provided with a pre-set diaphragm mechanism which auto-
matically closes the diaphragm down for the moment of shutter operation;

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 tempera-
ture fluctuations.
Do not remove the camera from its case the moment it is brought indoors from
cold to avoid sweating of its parts, especially the optical ones.
Do not touch the surfaces of the optical parts with fingers since it may damage
their coatings. Clean the optical coated lens surfaces with a clean soft cloth or cotton
wool wad slightly moistened with rectified alcohol or ether. The surfaces of the
mirror and the focusing device may be cleaned only if absolutely necessary with
a dry soft brush but in no case with humid cleaning agents.
Keep the camera closed in its case with the cap put on the lens.
Do not remove the lens from the camera without neefl to prevent dirt and dust
from getting both onto the surfaces of the lens optical parts and into the camera
itself.
If you don't use your camera for some period of time (a month and more) remove
the batteries from the camera. Keep the batteries separately in places inaccessible
for'children.
Load and unload your camera either indoors or in shade protecting it against
direct sun light and bright artificial light.
Always cock the shutter as far as it will go to avoid blank exposures.
Do not keep the camera with the shutter cocked for a long period of time
since it is likely to impair the shutter operation.
Do not try to rotate the shutter speed dial with the index moving along its short

Put the b.tt"ri.r into tfre in the following way: turn cap iZ counter-
clockwise as far as it will go,""-ur"remove the cap and take out the exhausted batteries
should there be any. Put new batteries into the compartment with signs ,,f "outward
(upwards). Replace the cap and turn it clockwise as far as' .it will go.'
Check the indicating light for operation. To do this, looking through the view-
finder eyepiece. press the release button 5 till a definite stop is felt. If the light-
emitting diodes (one or both) Iight up it means that the power supply operates
properly.
Load the camera with film in the following way:
- ,lift the film rewind crank 12, pull out the rewind knob 11 as far as it will go,
and open the camera back door;
- put a loaded cassette into the chamber 21;
- return the rewind knob11 to a locked position stightly turning.it, if required, to let
'the spool guide enter the cassette;
- draw out a film leader as long as to reach the camera edge and insert it into
the slot of the take-up spool 25 in so doing make sure that a sprocket 24 tooth engage
I a film perforation hoie;
I - close the back door 26, tightly pressing it to make the lock latch;
- to transport a nonexposed portion of film to the film gate, cock and fire the
shutter twice, In so doing the frame counter should be set at ,,0".
Should the film be wound tightly in the cassette, the film rewind knob wiil rotate
r when the shuttei is being cocked. If the film is loose in the cassette, the rewind
knob will fail to rotate at the first frames;
- set the speed of the film loaded in the camera by turning dial 13 till a correspon-
ding film speed vslue is click-stopped against the index mark 15.

Bear in mind that wrong setting of the film speed with the dial 13 will result
in wrong exposure.

SHUTTIiR SPEED SETTING
Turn the shutter speed dial 1? to bring a selected shutter speed opposite to the index
mark 18 on the camerq 9p plate.. In so doing the dial ls clic^k-stopped. Figures-gf
on the sh-uttjr sp-eed dial show shutter speeds in corresponding fractions a
second and ,,B" indicates a hand-controlled shutter speed. Shutter Jpeeds can be set
with the shutter both cocked and released. When taliing pictures at ,,B" the shutter
remains open for as- long as _the release button 5 is preis-ed down. To obtain a long
exposure turn the depressed release button counter-clockwise as far as it wi|1 g5
(,,T" position). The exposure over, return the release button 5 to its normal lmiddft)
position and release it. This will result in closing the shutter.
- To take a picture at ,,B" or long exposures one is recornmended to use a cable
release which can be screwed into th-e release button thread. In so doing the
camera should be mounted on a tripod.

BEAR IN MIND that sharp pressure on the release button results in camera
shaking at the moment of exposure and thus in blurring of the picture.
Whin taking pictures see to it that index marks on the release button and the
camera top plate (between,,T" and,,V") should be lined up.
To tak-e a picture with long exposure mount the camera on a tripod, set the
shutter speed dial l? at ,,B". slightly press release button 5 (the shutter should be set
beforehand in the ,,ready to fire" position) and turn it counter-clockwise as far as
it will go (.,T' position).
The exposure over, return the button to its normal (middle) position and release
it As a result the shutter will close.

press bush 6 downwards as f ar as it will go;
flip open crank 12 and rotate it in the arrow
direction unti I the f ilm leaves the take-up spool.
Tly and rotate the crank smoothly, without jerks,
and not too fast to avoid traces of static electri-

- pull film rewind knob 11 all the way out, open the back door and remove the cas-
sdtte;
- turn the cocking lever 19 and, holding the sprocket teeth 24 with your finger, make
sure that it is engaged: j
Do not try to take more than 36 shots. However if it has happened and the film, fixed
in the cassette, prevents full shutter cocking, unload the camera in the following way:
- press button 6 and hold it doWn rewinding the film into the cassette;
- remove the cassette;
- cock and fire the shutter:
- press button 6 to reset the frame counter to ,,0".
OPERATING THE SELF.TIMER
To use self-timer mount the camera on a tripod, then do the following:
- focus the image;
- press the release button 5 till a definite stop is felt and turn it clockwise (,V" po-
sition). This will enable you td set the aperture manually since the diaphragm
does not operate automatically when the self-timer is used;
- set the aperture and the shutter speed;
- cock the shutter;
- Wind the self-timer by turning lever I downwards as far as it will go in the
direction of the camerd top plate. Red light in the self-timer window indicates
that the self-timer mechanism is not cocked, gfeen light indicates that it is cocked;

- prcss the self-timer release button 2 and take yo\rr place in front of the lens.
Ttre shutter will operate no sooner than in ? seconds after pressing the button;
- self-timer operation over, return button 5 to its home position.
TAKING FI,ASH PICTURES
The camera shutter is synchronized for use with
electronic flashes. To connect a flash unit with the
camera, the latter is fitted with socket 4 on the front
wall of the camera.
The camera design provides as well for cable-
Iess connection of f-lash units. For this aim it is
fitted with hot-shoe 7 -
Bef ore mounting a flash unit on the camera
remove protective slrip-of16 from shoe 7.
The Shutter speed 1/30 s only can be used
for flash photograPhy.
The aperture ii selected in acbordance with the
instmctions given in the Instruction Manual on a
flash unit being used.
