BASIC OPERATION - CA-4 / 4s

INSTALLING THE BATTERIES

1. By using a coin, unlock the battery compartment cover by turning it counterclockwise (Fig. 1).

2. Remove the battery holder which is attached with the cover. Then, place three 1.5V G-13 type silver
oxide batteries (Eveready S-76 or equivalent) with the plus (+) side facing upwards (Fig.  2).4.butkus.org

3. Replace the battery compartment cover by turning fully clockwise (Fig. 3).

www.orphancameras.com





Note: Clean the batteries with a dry cloth or tissue paper before inserting and thereafter every six months.

           ⋅ Make sure that the batteries are inserted correctly, i.e., check polarity.

           ⋅ The shutter speed indicator LED and the action lamp will operate only when batteries are
       correctly installed and fresh.

BATTERY TESTING

To test the batteries, set the shutter operation mode selector to the "AUTO " position (Fig. 4). While looking
at the shutter speed indicator scale in the viewfinder, slightly depress the shutter release button. If the
batteries are in good condition (battery voltage is high enough), at least one of the indicator LEDs will light
up. If an LED fails to illuminate, the batteries are too weak and need to be replaced, they are incorrectly
inserted or the shutter operation mode selector is set to " X " or "B "

FILM LOADING

      Your Chinon CA-4 camera can be used with any type of 35mm film.





        1. Pull up the film rewind knob until the camera back pops open (Fig. 5).


        2. Then, insert a film cartridge into the film chamber with the protruding end facing the bottom of the
      camera (Fig. 6).

3. Push in the film rewind knob and www.orphancameras.comslightly turn the knob in either direction until it catches the film
       cartridge spool.

        4. Insert the trimmed end of the film into a slot of the multi-slotted take-up spool.

        5. Turn the shutter operation mode selector to the " X " position and advance the film while holding
       the film lightly
       down onto the transport sprockets.

        6. Release the shutter if necessary and advance the film until the sprockets engage with the upper and
      lower perforation
         of the film (Fig. 7)

        7. Close the camera back firmly until it locks with a click.

        8. Turn the film rewind knob gently until the film slack is taken up and the rewind knob stops. Do
       not force or further rewind the film.





        9. Advance the film and release the shutter three times ((Fig. 8). The rewind knob should rotate
       counterclockwise
       when the film is advanced and the "l" marking should appear in the frame counter window (Fig.
        9).

       10. Turn the shutter operation mode selector to the "AUTO" position and start to take pictures (Fig.
       10).

MEMO HOLDER

Your Chinon CA-4s camera has a built-in memo holder feature. To utilize the memo holder feature, simply
cut off the top
  of the film box and insert it into the memo holder located on the back cover of your camera. This will
enable you to
  quickly and easily identify the type of the film and the ASA speed used in your camera (Fig. 11).

 I added original "illustrated" manual to end of this manual.

www.orphancameras.com





FRAME COUNTER

Your Chinon CA-4 /4s is equipped with a frame counter which displays the number of exposures and resets
automatically
  upon opening the camera back. When the camera back is opened, the counter shows " S " indicating the
start of the
   picture taking process.

When film is loaded according to the procedure previously described, the counter displays " 1 " indicating
the camera
   is ready for the first exposure.4.butkus.org

Every time the film advance lever is turned the counter will proceed one stop forward. The number 24 and
36 are colored
   in orange to warn the end of commonly available films (Fig. 12).

The action lamp (LED) located on the front of the camera body will illuminate while the shutter is activated.
The subject
  can easily observe when the shutter is released.

FILM ADVANCEMENT

Make sure the film has been loaded properly. Operate the film advance lever through a full stroke. When the
film end
   is reached the film advance lever may stop before the lever is fully turned. Do not force the lever! Stop
winding at
  once and rewind the film (Fig. 13). Please refer to "Unloading Exposed Film ".

      Note: ⋅ When the batteries are dead, you can still use CA-4 / 4s camera. Reset the shutter
       operation mode selector from "AUTO" to "X" which will provide a shutter speed of 1/l00 sec.

ASA/DIN SETTING

      The film speed dial located on the top of the camera is coupled directly to the internal exposure
       control circuitry. The correct exposure factor for the film is automatically set by aligning the ASA

number of the film you are using withwww.orphancameras.comthe index mark on the camera body. The ASA number of the
       film is printed on the film box or the instruction sheet packed with the film.





      Turn the film speed dial by lifting up and align the appropriate ASA number with the white index
      mark. Be sure to check the ASA number whenever you put a new film into the camera (Fig. 14).





FOCUSING

Your Chinon CA-4 / 4s has three built-in focusing aids.

        1. The center of the viewfinder is split image with a microprism collar which is surrounded by
      ground glass. When the camera is in focus, the image of these focusing aids become sharpest.
      While observing the subject through the viewfinder, rotate the lens focusing ring until the
      upper and lower split image match up to form one uniform image (Fig. 15). This split image
       focusing is particularly helpful when the subject is dominated by vertical lines.

        2. The microprism is also helpful. When it is out of focus, the image on the microprism will
      be composed of a collection of asterisks (Fig. 16). These sparkling asterisks will disappear
     when the focus is properly adjusted. You can double check the focus setting by the image on
       the

3. You can also focus indirectly. Actuallywww.orphancameras.commeasure or estimate the camera-to-subject distance
      and set the lens focusing ring to the appropriate setting (Fig.  17).4.butkus.org

AUTOMATIC EXPOSURE

      Your CA-4 /4s camera features TTL, center weighted full aperture light measuring automatic
      exposure control. As long as the shutter operation mode selector is set to "AUTO", you do not have
       to worry about the exposure factor (Fig. 18).

      The sensitive and accurate internal circuitry will compute the correct exposure for the photographic
       condition and control the shutter speeds steplessly from an 1 second time exposure to a fast 1/1000
       second.

     When the shutter release button is depressed halfway, the exposure control circuit is energized and
       will be in the monitoring stage (Fig. 19). You can see the computerized shutter speed displayed in the
       viewfinder by a red LED (Fig. 20). If the lens F stop or the aperture size is too large for the lighting
       condition, the over exposure indicator at the top of the scale will flash (Fig. 21). When this happens,

stop down the lens diaphragm by turningwww.orphancameras.comthe lens F stop ring or use a film with a lower ASA number.





      Another alternative is to use a ND filter in front of the lens. They are available as accessories from
      your local camera store.
         If the displayed speed is 1/30 sec. or slower, use of a tripod is recommended. Or you can increase the
       shutter speed by opening the lens diaphragm. Use of a flash unit is also suggested. Please refer to
      "Chinon dedicated flash system".

         If the computed shutter speed is even longer than one second (semi-darkness condition), the under
      exposure indicator at the bottom of the scale will light up and flash when the available light is less
       than - 2EV (Fig. 22).

Note: F stop selection: The following may be used as a guide to determine the lens F stop when you are
using the camera; Sunny day outside . . . F/8 -F/16
Cloudy day outside . . F/4 - F/5.6
Inside . . . . . . . . . . . . F/1.9 - F/2.8 (without flash)

SHUTTER RELEASE

Your Chinon CA-4 /4s features a two-stage shutter release with a safety cover to prevent accidental shutter
release or battery drain. When the shutter release button is depressed halfway, the electronic circuit starts
functioning.





When the button is fully depressed, it will trigger the shutter. Always hold the camera steady and gently
depress the shutter release button to make an exposure.

UNLOADING EXPOSED FILM

www.orphancameras.com
          When the film in the camera is fully exposed the film advance lever will stop.

         Do not attempt to force the lever any further. Rewind the film and replace with new film.
            Push in the rewind button at the bottom of the camera (Fig. 23). Unfold the rewind crank of
              the rewind knob and turn the rewind crank clockwise (Fig. 24).

          You will feel friction as the film is rewound. Suddenly, when the film is rewound completely,
              the friction will decrease, then lift the rewind knob to open the camera back (Fig. 25).

          When the camera back is opened, the frame counter will automatically reset to the " S "
               position. The rewind button on the bottom of the camera will pop out upon the next
            advancement of the film advance lever.

             Note: Your exposed film should be processed without delay.

CONVENIENT FEATURES:
INTERCHANGEABLE LENSES

DEPTH OF FIELD

Depth of field designates the nearest and furthest limits of the area that will be sharp in the picture in front
of and beyond the subject. The larger the lens opening, the shallower is the depth of field. The smaller the
lens opening; the greater the depth of field becomes (Fig. 29 & 30).





Depth of Field Scale:

The depth of field scale indicates (after focusing) the approximate area that will be sharp in the picture.
Locate on the depth of field scale the corresponding pair of f/stop figures. The distance between these two f/
stop figures on the focusing ring will be the area of sharpness in your picture (Fig. 31).

SELF-TIMER

The self-timer when set, trips the shutter mechanismwww.orphancameras.comafter a delay of 7-12 seconds. This feature is useful
should the photographer wish to be included in the picture, and is also useful for taking pictures at slow
shutter speeds when a cable release is not available.

When using the self-timer, the camera must be mounted on a tripod, or a solid support of some  kind.4.butkus.org

To operate, move the self-timer lever counterclockwise as far as it will go. Advance the film transport lever.
Upon pressing upward on the self-timer lever with your finger. the self-timer mechanism will start to
operate (Fig. 32).





Note: Do not depress the shutter release button, since the self-timer mechanism will not operate and the
shutter will be released instantly.

Do not advance the film transport lever until the self-timer operation completely stops.

INFRA-RED PHOTOGRAPHY

Your CA-4 / 4s camera accepts infra-red film. To use infra-red film an extra focusing adjustment must be
made. After focusing note the figure that is adjacent to the green marking on the distance scale of the lens
(Fig. 33), then move that figure over to the infra-red mark engraved on the lens. This adjustment is only
required for black and white infra-red film. When using a color infra-red film, you should focus in the
normal way.

Note: Read the instructions carefully packed with the infra-red film for further information.
