GETTING READY
Take your Mamiya/Sekor CWP in hand and notice the fine balance and convenient location of the
controls.View original page 3Page 4 · Read text
LIGHT METER BATTERY
Now, turn the camera over and turn the battery
cover (27) counterclockwise with a coin to open.
Insert provided battery (1. 3V) so that positive (+)
side faces the back of the cover. Replace cover.
Your meter is now ready to use.
CARE OF MERCURY BATTERY
Positive (+) side and negative (-) side of the battery are as
shown by drawing. The battery will last approximately one
year depending on the frequency of use.
Dispose of the exhausted battery in a safe place. It is
dangerous to take it apart or throw into a fire.
You need a replacement Wein Air battery.
IMPORTANT
In switching light meter sensitivity selector
(4) from high (H) to low (L), or vice-versa,
be sure to press down with fingers 2 levers
in front and back of shutter speed selector
knob.
To conserve on batteries, always make sure
to have light meter sensitivity selector (a)
on high range side unless light condition
demands shifting to low range necessary.
Sometimes, you may have to open back
cover with winding lever half stroked
because old roll is at the end. Before
loading a new roll, be sure to push winding
lever all the way to the end of the stroke in
order to reset frame counter to start position
(S).View original page 4Page 5 · Read text
The point which corresponds to F 1. 7 in the
exposure indicator is the center between 2 and
1.4 and is indicated by the arrow in the figure
on the right.
LOADING FILM
All 35mm film, black and white, color, 20 or 36 exposures can be used. Always load film in subdued
light.
1. Open back of camera by
pulling out the slide lock. Pull up
the rewind crank knob (15) and
insert the 35mm cartridge in the
chamber (16). Return the rewind
crank to its former position if it
does not position itself turn
handle to right or left until it fits
in place with a click.
2. Turn the take-up spool (18) until the slit appears ; insert
end of the film in the slit (fold end of film for tight fit, if
necessary), wind the film on the spool for one turn. Be
sure the lower edge of the film is against the lower flange
of the spool and that the sprocket teeth engage the film
perforations.
3. Next, turn the rewind crank (15) in direction of the
arrow until all film slack is taken up. Check again to
make sure the sprocket teeth engage the film
perforations close and lock the back.
4. The letter S appears opposite the arrow in the
exposure counter window
(5). Advance film a single stroke and depress shutter
release button after each stroke. Continue this until the
figure 1 appears opposite the arrow. The camera is now
ready for the first picture.View original page 5Page 6 · Read text
6. Each time the film is advanced the rewind lever will
turn this assures proper film action in the camera.
7. The shutter is wound when film is advanced ; next
frame can only be advanced after shutter is released.
USING THE EXPOSURE METER
The Mamiya/Sekor CWP incorporates a most advanced and sensitive CdS meter.
It's wide range opens up new picture-taking opportunities . . . . this is how to use it:
1. Lift the shutter speed dial (3) and by turning match the
ASA film speed (22) with the red mark on the lower portion
of the dial. The meter is now coupled to the film speed.
2. Under normal light conditions the sensitivity selector
lever (4) is set on H. This position conserves battery life.
For low light conditions set the selector lever at L.
3. Now, point the camera at the
subject or scene to be
photographed. One of two
choices is now possible: (1) If the
shutter speed is important (as in
sports events) this should be set
first and then the correct exposure
regulated by turning the lens
aperture ring (8) until the pointer
is centered in the exposure meter
window (26). (2) If the depth of
field is important (as in scenery,
etc.) set the lens aperture ring to
the desired F stop. Then turn the
shutter speed dial (3) until the
pointer is centered in the
exposure meter window (26).
4. Shutter speeds are set in click stops. If meter indicates an in-between speed, move shutter to
nearest click stop and make adjustment with aperture for proper exposure.
5. When pointer stays in the red portion in either H or L position it indicates too much or insufficient
light for picture taking.View original page 6Page 7 · Read text
The exposure meter is a reflected light type meter; used properly, excellent exposures can be
expected every time. Here are some helpful hints on exposure:
Since this type exposure meter measures the light reflected from the object to be
photographed, it is necessary to take a meter reading as near to the object as possible
and thereby exclude extraneous light which can affect the exposure.
Portraits
Approach the subject and take the meter reading close to the face. If part of the face is darker,
measure both light and dark areas and use the average.
Landscapes
To expose properly for landscapes, tilt the camera slightly downward, thereby restricting the amount
of light from the sky, which would affect the meter reading.
Backlighting Photography
When shooting a silhouette, measure the light from the bright part of the background. When an object
is to be photographed by backlighting, measure the light from the object at close range so that the
light from the background will not influence the meter reading. When the object and the background
are to be photographed at the same time, first measure the darkest part of the object, then measure
the light from the background and use the average value.
FOCUSING AND VIEWING
The Mamiya/Sekor CWP is a single lens reflex you see your picture and take your picture through
the same lens. What you see you will get on the film when yon press the shutter release. There are
no problems of parallax. You obtain perfect composition with any lens and you can check the depth of
field at any time before clicking the shutter. Furthermore, you can follow the action up to and
immediately after the picture is taken.
FOCUSING
The focusing ring (7) is turned in either
direction until the image in the small circle
of the finder is sharp. The micro-diaprism
disappears at this point, indicating the
sharpest point of focus. It reappears when
out of focus.View original page 7Page 8 · Read text
DEPTH OF FIELD
To check the depth of field, the preview lever on the lens (9)
is depressed until 'M appears. This closes the diaphragm to
the preselected F value and you can now see exactly the area
of sharpness which will appear in the picture. When the lever
is returned, `A' appears and aperture adjustment becomes
automatic. When in "manual" aperture the viewfinder will
become dark until it returns to "A" automatic.
DEPTH OF FIELD TABLE
Depth of field can also be determined by
consulting the scale on ring(13). This is helpful
when the lens is stopped down so that it cannot be
checked with the preview lever due to low light
transmission.
For example, with the standard lens and the
aperture set at F 11, focused at 16 feet, the F ii on
,the depth of field ring (13) will point to
approximately 10 feet and infinity. This indicates
the range of sharpness within which all will be in
focus. Consult table for other distances and
apertures on page 12.

depth-of-field chartView original page 8Page 9 · Read text
The lens has an automatic pre-set diaphragm. While focusing, it is wide open and provides the
maximum brightness in viewfinder for ease in composing and focusing. When the shutter is released,
the diaphragm closes to the pre-set aperture for the instant of exposure and immediately reopens
thereafter. In this brief time the viewing screen snaps up, permitting the picture to be taken and then
returns to the viewing position.
SHUTTER SPEEDS
The shutter speed dial (3) is a single shaft, stationary type with an
equally spaced multiple scale. A click stop is provided for each
speed. The shutter dial can be set over a range of T to 1/1000 by
turning it either to right or left, before or after film advance.
When the shutter is released with the dial set on 'B', the shutter will
stay open during the time the shutter release (2) is being depressed.
When the shutter release (2) is depressed with the dial on `T', the
shutter opens and stays open until the shutter dial (3) is moved to 'B'.View original page 9Page 10 · Read text
SELF-TIMER
This feature makes it possible for the photographer to get in
the picture. It can also be used for slow speeds with camera
mounted on a tripod or held against a stationary object by the
photographer.
When the self-timer lever (10) is turned counterclockwise
approximately 180°, the timer allows ten seconds before it
trips the shutter. Time can be adjusted freely over a range of
70° to 180° with the lever.
When the self-timer actuating button (11) on the lever shaft
is depressed, the timer starts to operate. After the self-timer
has been set, the shutter can still be released by pressing the
shutter release button (2).
In this case, the self-timer action stops.
Further, before actuating the self-timer, the shutter must first be wound. When releasing the shutter
with the self-timer, the automatic aperture control mechanism works in the same way as when the
shutter is released by depressing the shutter release button.
HOLDING THE CAMERA
Lightly support the bottom of the camera with the palm of
the left hand ; adjust the position of the camera so that the
thumb and forefinger of the left hand can reach the
focusing ring (7). Place the palm of the right hand against
the end of the camera body. Then the forefinger of the
right hand will automatically be near the shutter release
button (2) and the thumb will be on the film advance lever
(1). Bring the finder window to the level of the eyes and
rest against the forehead. This will assure steady holding of
the camera.
In taking vertical pictures,
the camera is to be held with
the film advance lever
upward. Procedure is the
same as for horizontal
pictures. Hold the camera
with the left elbow as close
to the body as possible.View original page 10Page 11 · Read text
When the camera is to be held with the film advance
lever (1) downward, with the right thumb on the shutter
release button (2), support the camera with the palm of
the right hand. Place the left thumb and forefinger on
the focusing ring (7). Hold the right elbow close to the
body.
The above camera positions are the same when other
lenses are used.
When taking pictures with speeds of less than 1/30
second, use a tripod or rest the camera on a steady
supporting base to prevent movement when the shutter
is released, or when using the self-timer.
FLASH PHOTOGRAPHY
The flash terminal (21) has two fittings, one for
FP and one for electronic (X contact).
The relationship between terminal, exposure time
and flash bulb is shown in the table below.
The flash terminal and the shutter speed time dial
are synchronized and indicated by symbols of the
same color. When using the FP flash you can use
any of the shutter speeds marked in green on the
shutter speed dial (3). When using the electronic
flash you can use any of the shutter speeds
marked in orange on the shutter speed dial (3).View original page 11Page 12 · Read text
CHANGING LENSES
To change the lens, hold the lens cylinder
in the right hand and turn
counterclockwise. When mounting a lens,
turn clockwise until it stops. When
mounting or detaching a lens, hold the
section where the depth of field scale (13)
is marked.
When the lens is detached, the reflecting
mirror becomes visible. Never touch this
mirror. If dust is found on this mirror,
remove by blowing it away with a rubber
bulb or brushing with a camel's hair brush.

USING INFRA-RED FILM
With this film, use the red ''R' as the marker on the
depth of field scale (13). After focusing through the
viewfinder note the distance on the distance scale,
then turn the ring until the `R' is opposite the same
distance.
If trying IR, go Digital. Lots of options available.
UNLOADING FILM
After 20 or 36 exposures have been taken, press the sprocket
release button (19), raise the film rewind crank (15) and turn
in direction of arrow. A slight tension can be felt as the film
comes off the take-up spool. Remove the film cartridge from
camera.
The sprocket release button (19) returns to its normal position
when the film advance lever is operated.
Important : Do not force film advance lever when at end of
film. Press the sprocket release button (19) to relieve tension
and then rewind film.View original page 12Page 13 · Read text
