We wish you all success with this modern reflex camera. You own a camera with the novel metal-blade focal-
plane shutter for maximum shutter speed stability and minimum synchronization for electronic flash
photography. The camera is fitted with a through the-lens light metering system for a coupled determination of
shutter speed, diaphragm numeral, and film speed. Metering is on the center-weighted method and gives pictures
true to the subject.
Before you start snapping away happily will you please read these Instructions for Use carefully. You will avoid
trouble with the camera and disappointments with the pictures.

Opening the camera back
Pull rewind button (6) upwards to its hard stop, thus the camera back is unlocked and can be hinged open.
Simultaneously, exposure counter (11) automatically returns into its initial position.
Film loading
Insert the cartridge and observe that wire- brackets (25) do not stand upwards. Turn at the knurled spool disk, if
required. Pull the film leader to the green mark (24) and pass it under support (22) so that the teeth of film
sprocket (21) engage in the film perforation.
Should the film be heavily warped, put a wire bracket on it by rotating the spool disk. Push rewind button (6) in
again by rotating it a little, if necessary.

Closing the back.
The back locks automatically when you press it to
the camera body. at the latch side.
www.orphancameras.com
Cocking and winding
Rapid wind lever (10) has a dead stroke of about 15 deg. till the mechanism
engages. This makes for safety at series exposures. Swivel lever (10) to its
stop, move it bock and depress shutter release (3). Repeat the process and
finish up by cocking the camera again. The automatic exposure counter (11)
will now read exposure 1.
Film speed setting
Automatic exposure control demands setting of the film speed. Pull the
knurled ring of the shutter-speed dial (1) up and turn it till the DIN or ASA
film index on dial (13) will meet the white mark (12). The rim locks when
released.

Shutter speed setting
Symbol f for electronic flash photography (about 1/125sec)
for time exposures; the shutter remains open as long as
Setting B
the shutter release is depressed
1 sec. to 1/15 sec. (orange) for low light photography; a tripod is needed
1/30 to 1/1000 (white) for satisfactory light photography
Rotate shutter speed dial (1) till the desired speed matches the orange triangle.
Diaphragm setting
Set the desired diaphragm number on
diaphragm setting ring (17) of the lens
opposite to the mark on the lens mount.
When lenses with automatic pressure
diaphragm (ADB)-are used, the
diaphragm remains fully open and closes
to the set value only when the shutter
release is pressed. The diaphragm opens
in the same instant the shutter has run
down. By changing the diaphragm
operation selection switch (14) from A
(automatic operation) to M (manual
operation) or by actuating the metering
key (2) it becomes possible to check the
depth of field already on the viewfinder
image.
Automatic exposure control system
There are two modes of light metering:
1. Metering by altering the diaphragm numeral at the lens with pre-selected shutter speed (being the preferred
method for general objects in satisfactory light).
2. Metering by altering the shutter speed with pre-selected diaphragm numeral (being recommended for low light
photography with a certain depth of field required).
Metering at pre-selected shutter speed
Set the shutter speed, press metering key (2). Turn diaphragm setting ring (17) until the meter needle, visible in
the viewfinder, will have centered to the circular mark. When the needle stands in the + range, an overexposure
will be obtained while its position in the --range will result in an underexposure. The diaphragm opens and closes
www.orphancameras.com
on rotating the diaphragm setting ring correspondingly thus compensation between subject brightness and the
combined shutter speed, diaphragm, and ASA/DIN settings is performed. 4www.butkus.org
Metering at pre-selected diaphragm number
Set the diaphragm numeral, press metering key (2). Turn shutter speed dial (1) until the meter needle visible in
the viewfinder will have centered to the circular mark. When the needle stands in the + range, an overexposure
will be obtained while its position in the--range will result in an underexposure. Don't set any intermediate
shutter speeds between the indexed positions. Should you not succeed in attaining a perfect balance, you can
make a precise correction by the diaphragm setting ring which may, of course, be set to intermediate values, too.
Metering with lenses without automatic diaphragm system
How to control:
Set the diaphragm to its smallest diaphragm number - focus the lens--balance the system by stopping down.
Functional range of the automatic exposure control system
Outside of the range of the Table below the metering system is switched off. The meter needle is in rest position
below the circular mark in the minus range. Metering cannot be made with the "B" or symbol f .
ASA min. and max speeds ASA min. and max times
12 to 16 1 to 1 1/25 200 - 330 1/4 to 1/1000
20 - 32 1 to 1/250 400 to 660 1/8 to 1/1000
40 - 65 1 to 1/500 800 to 1300 1/15 to 1/000

Focusing
Focusing is possible as to metering wedges, microprism screen, or circular ground glass area.
www.orphancameras.com
Focusing on the measuring
wedges
Turn the distance setting ring
until defined outlines of the
picture parts will stand
opposite to one another.
Focusing on the microprism screen
Maximum sharpness is attained when the image in the microprism screen is clear and does not flicker. Don't use
the ground glass Fresnel for focusing.
Depth-of-field scale
The depth of field attained with a certain diaphragm setting can be read
on scale (15).
Example: Distance 3 meter, diaphragm numeral 8, depth of field extends
from 2 metes to 5 meters. 4www.butkus.org
For checking the depth of field on the viewfinder image, too, depress
metering key (2), set selection switch (14) to M and the switching lever
(of PANCOLAR 50 mm fl1.8) to its lower position, resp,
Infrared photos require a slight correction in focusing; let the determined
distance meet the infrared mark on the lens.
Releasing and cocking
www.orphancameras.com
Please note before pressing the shutter release:
1. The signal (must be a red triangle visible when the shutter is
wound) is visible in the viewfinder on the left: camera not ready for
snapping - swivel the rapid rewind lever (10) to the stop.
2. For shutter speeds of '/,s seconds and slower use a tripod and cable
release. Press shutter release (3) smoothly right across the easy going
section. Don't depress suddenly! Prepare for another snapping by
cocking again.
Self-timer
Cock the shutter. Turn lever (5)
upwards to its stop. Press release
(4)--the self-timer will now run for
about 8 seconds. Do not cock the
shutter while the self-timer runs.
Film changing
Observe the exposure counter for
the number of pictures you can
take with the film in your camera
(12, 20 or 36 exposures). After the
last exposure press rewind release
(27) (it locks). Tilt the folding
rewind crank (7) out of rewind
button (6) and turn it not too fast
in the direction of the arrow
(indicated on crank (7). You will
feel the end of rewinding by a
somewhat increased resistance
with subsequent easy running. Pull
the rewind button up to the stop,
www.orphancameras.com
the camera back being thus
released, and take the cartridge out.
Note. Should you have exposed a few more frames than specified on your film packing it might be possible that
the rapid wind lever can only be turned partially. Do not use force in this case but rewind the film.
Lens changing
Any lenses having the international M 42 x 1 PRAKTICA thread can be
applied. Grip the lens body and unscrew it in counterclockwise direction;
screw in the other lens in clockwise direction to the stop. 4www.butkus.org
Flash photography
This camera has been designed for synchronization of flash bulbs and
electronic flash units. Flash units provided with a center contact are
pushed into accessory shoe (8). Connect flash units fitted with synchro
cable and flash contact with flash socket (30). Set the symbol ( f or 0) of
the relevant type of flash unit on the shutter speed dial. The firing circuit
is only closed as long as the shutter is running down.
Note the guide number of your flash unit and make the aperture or
distance calculation (use the calculating disk on the flash unit).
The use of flash bulbs
www.orphancameras.com
For fast burning flash bulbs the speed dial is set to the symbol or 0 to a
shutter speed longer than 1/30 sec.
The use of electronic flash units
These will be synchronized at setting to the symbol t which
corresponds to a shutter speed of about1/125 sec. Longer shutter
speeds can be set.
Battery replacement
The automatic exposure control system is powered by a PX 625
mercury oxide element or a corresponding type of 1.35 Volt rated
voltage.
Open the battery compartment (28) with the aid of a coin. Pay
attention for + and -- symbols when loading the battery. Insert the
power source accordingly and then screw in the lid again.
Life of the power source will be about 2 years.
Don't recharge old batteries, don't put them into the fire! There is
danger of explosion!
www.orphancameras.com
Care of the camera
Operation according to instructions and proper care are essential preconditions for trouble free function of this
high-precision instrument. Protect it from shocks, blows, dust, and moisture, clean cartridge and spool
compartments, film track and camera back with a soft brush in suitable intervals. Do not exert any pressure onto
the shutter blades and do not touch them with your fingers. Dust the mirror with a soft brush only if absolutely
necessary. Don't clean the camera with organic solvents, such as spirit, varnish thinner or the like. The camera
will work unobjectionably within the temperature range of +40 °C to -10 °C. Above and below this range for
some reasons the mechanical and electrical and electronically functions may fail. If the camera e.g. undergoes
sudden changes in temperature, condensate will form which will cause damages by corrosion.
Special attention should be paid to the battery and its contact points. Check them in short intervals and clean, if
necessary. Since the battery is susceptible to low temperatures, protect it against cold and remove it from the
camera when not being used for some time.
