IMPORTANT! BASIC STEPS IN PHOTOGRAPHING





(1) Insert CdS battery with plus (+) side up

(2) To test battery condition, Fig. 6 depress the battery test
button and observe test light
(3) Load 35 mm film in 20 or 36 exposure cassette

Mercury batteries are no longer available.

Look for Wein Air batteries as a replacement.

(4) Set ASA (or DIN) speed dial in accordance with the
film speed specified on the film box

(5) Set either the shutter speed or lens opening according to
your photographic need

(6) Focus the lens

(7) Release the shutter (Fig. 8)





LOADING THE CAMERA

Use 35 mm film in 20 or 36 exposure cassette. It is recommended to load and unload camera in subdued light,
e.g. shadow of your own body and not in direct sunlight.





(1) Pull up film rewind knob until camera-back pops
open. Swing open camera-back

(2) While rewind knob is still fully pulled up insert film cassette into chamber with protruding end toward
bottom of camera. Press in film rewind knob. If it does not go in all the way, turn it until it does.




(3) Insert end of film into slot in
take-up spool and engage
perforation of film with tooth in
spool slot. Place thumb lightly over
film on bottom sprocket wheel and
operate film advance lever until
upper sprocket wheel engages film
perforations. When advance lever
stops, free it by depressing shutter
release on top of camera. Make
sure that film lies flat between
guide rails (Fig. 10). Close
camera back firmly.





(4) Operate film advance lever, depressing
shutter release until figure " 1 " is lined up in
the exposure counter window. In this position
the camera is ready for the first exposure to
be made (Fig. 11).





To be certain that the film transports correctly, take up any film slack in the cassette by turning the rewind crank
clockwise till resistance is felt. When advancing the film the rewind knob should turn anticlockwise. This is
evidence that the film is loaded correctly. If it does not, start loading again.

SETTING FILM SPEED (ASA/DIN)





The ASA (or DIN) speed of the film is specified on the
film box or in the instruction sheet packed with the
film.
Pull up and rotate the outer rim of the shutter dial until
desired ASA (DIN) number of the film appears in the
window on the top of the film shutter speed dial (Fig.
12).





Also rotate film type indicator dial so that the
film type inserted shows to its pointer (Fig.
13). This will remind you of the type of film
you are using.

Some ASA (DIN) numbers are represented by
a dot only. The chart below specifies the ASA
(DIN) numbers.

CORRECT EXPOSURE
Correct exposure can be made by setting F
stops on the lens and correct combination of
shutter speed. As the CHINON CX camera
has a built-in through-the-lens CdS exposure
meter, you can take correctly exposed
photographs.

(1) See the subject through viewfinder. Press
down the exposure meter switch (Fig. 14).





Depending upon the subject, rotate either shutter
speed dial or F stop ring until the exposure
indicator needle in the viewfinder comes to the
complete horizontal position
(Fig. 15). If the needle is above the horizontal
position, it is overexposed (Fig. 16). Change the
shutter speed to a faster speed or use a smaller
lens opening so that the correct exposure
combination can be obtained. If the needle is
below the horizontal, it is under exposed so that a
slower shutter speed or bigger lens opening must
be set (Fig. 17).





2) When an ASA setting is used in conjunction
with speeds and/or apertures which are beyond
the range of the TTL meter a red signal will
appear in the exposure zone of the viewfinder
(Fig. 18). When the red signal appears it
indicates that a flash unit should be used to
supplement existing light.

FOCUSING
Release the exposure meter switch and
AUTO/MANUAL control on the lens to
position (Fig. 19).

Turn the distance ring first in one direct
then in the opposite direction until
microprism in the center of the image in
the viewfinder is sharp (Fig. 20). Picture is
now focused. The distance scale may also
be used for focusing. Estimate or measure
the camera to-to-subject distance in feet or
in meters, then turn focusing ring. So the
figure representing that distance is
opposite the index line.





RELEASING THE SHUTTER
Hold the camera as steady as possible and press the shutter release slowly and smoothly. When using slower
speeds ranging from 1/30 to 1 second and " B" (bulb) in poorly lit areas, use a tripod or other firm support to
prevent blurring the picture.

SETTING THE SHUTTER

The length of time for the film to be exposed to light can be adjusted by shutter speed setting. "60" (1/60
second) is recommended for subjects not in motion.

It is recommended to use shutter speeds ranging from 1/125 to 1/1000 for subjects in motion. 1/1000 second
speed will best ' freeze" fast action.

The " B " setting can be used for long exposures at night, using street lights or electric signs, or under poor light
conditions when flash unit is not used.





UNLOADING THE CAMERA

When the red figure " 20 " or " 36 " (corresponding to 20- and 36-exposure film) appears in the exposure
counter window lined up to the index mark, the end of the film has been reached.





Take the following steps for rewinding film into
cassette.

(1) Unfold crank on rewind knob (Fig. 21).

(2) Press in all the way rewind release button on
camera bottom (Fig. 22).

(3) Turn rewind crank lever clockwise. Tension is felt as the film is rewound from the take. up spool into the
cassette. Stop rewinding when tension is released. Open camera back (by pulling out rewind knob all the way)
and remove the film. Have film processed without delay.


DEPTH OF FIELD
A zone of the picture in front of and behind your subject will also be sharp. The depth of this zone depends on
the aperture selected. If you wish to know how much of an area will be sharp in the final picture, it can be
predetermined in two ways:

(A) Depth of Field Pre-viewer
Slide the AUTO/MANUAL aperture opening switch to "M" (Manual) position. Set the lens to the selected
aperture opening of the F stop ring. This will enable you to preview the area of sharpness in the picture before
taking.



(B) Depth of Field Scale (Fig. 23)
After setting the lens opening and having
focused on your subject, the area of
sharpness in front of and behind your
subject can be determined on the Depth of
Field Scale. Locate on the Depth of Field
Scale the same two F numbers
corresponding to stop you have set on the
F stop ring. The distance between these
two F numbers on the focusing scale will
be the area of sharpness in your picture.





SELF TIMER
The self-timer permits the photographer to get into
the picture. Place camera on tripod or other firm
support (tripod socket is on bottom of camera). Get
camera ready for exposure as usual. Push down
self-timer lever (Fig. 24).



Depress shutter release to start self-timer. Exposure will be made approximately 8 seconds after the release has
been pressed.

FLASH PICTURES
Most types of flash bulbs and also electronic
flash can be used for flash pictures.

When using flash bulb No. 5, 5B, 25, 25B,
M5, M5B, M2, M2B, AG1, 6, 6B, 8, connect
the flash cord to flash socket " M ". When
using electronic flash or SM flash bulbs,
connect the flash cord to flash socket "X"
(Fig. 25).




The use of Nos. 5, 5B, M5 and M5B flash bulbs as well as electronic flash. Nos. 6, 6B, 8 flash bulb is
recommended for shutter speeds from 1/30 to 1/125 sec.

The use of Nos. M2, M2B, AG1, AG1B. SM flash bulbs is recommended for shutter speeds from 1/30 to 1/60
sec. Cordless flash units are slipped into the accessory shoe on the top of the camera. The accessory shoe may
also be utilized for a flash unit having a synchro cord.

MULTIPLE EXPOSURE
To superimpose two or more exposures on one
negative, support the camera on a rigid tripod to
ensure correct framing. Make the first exposure in
the normal way, then, without moving film
transport lever, slide the multiple exposure lever
(Fig. 26) as far as it will go to the left.

A red signal appears in its cutout window indicating
that the film transport lever can be wound, but will
only set the shutter and not transport the film. On
releasing, a second exposure is made on the same
film frame. This procedure can be repeated to obtain
any numb her of exposures on one negative. If the
multiple exposure lever has been set but is in fact
not required, you can manually push it back to
cancel its effect.



CHANGING THE LENS
A 55 mm lens is the proper focal length for general purpose picture taking. Any Chinon telephoto and wide
angle lens or Pentax, Prinzflex or Sigma lens mount can be used. To remove the lens, push up the exposure
switch on the camera body, holding it in one hand and grip the lens with the other, turning counter clockwise
until it is removed.

To replace the lens, turn clockwise until secured in position finger-tight.

IMPORTANT NOTE
When installing or removing the 55 mm F/1.2 Chinon lens the exposure switch must be in " OFF " position
(Fully up) or the focus ring must be turned to a distance setting of less than 0.9 M (3 feet) to avoid damage to
the rear lens element.

The following interchangeable lenses and accessories for CHINON Single Lens Reflex are available.
