BASIC OPERATING INSTRUCTIONS
1.Setting the Exposure Mode

The CP-9AF features a three stage programmed AE mode, (P. P-Action P-Creative), aperture priority (A) mode, a metered manual (M) mode and bulb (B) mode.

To set the exposure mode, simply press down the desired mode at the corner of the exposure mode selector One press on P mode will result in normal "P", another press for "P-Action" and a third for "P-Creative" (Fig. 18).

See Exposures Modes for further details.

2. Programmed AE Modes

In the programmed modes, the camera automatically determines the aperture and shutter speed in accordance with the ambient lighting conditions and the Luminance of the subject to achieve an exposure. Programmed AE modes are ideal for general picture taking by eliminating troublesome exposure settings caused by changing light conditions.

For general snap shots and scenic pictures, the P mode (normal program) is ideally suited.

1) Push the "P" corner of the exposure mode selector until this program mode is indicated on both the LCD panel and within the viewfinder (Fig. 19).4.butkus.org

2) Pushing the "P" corner again and again cyclically switches the mode, enabling you to make any preferred programmed AE mode setting.

NOTES:
When the shutter speeds on the LCD panel and the "down-arrow " mark within the viewfinder both blink, an optimum exposure for the current lighting situation has outstepped the AE linked range.

When the required shutter speed is slower that 1/30 second, the shutter speed digital LED within the viewfinder will change its color from green to orange, as a warning to possible camera shake. Either use an electronic flash or a tripod to help avoid blurred pictures.

Mode Reset Button
When you want to quickly set the camera to the normal program mode from P-Action, P-Creative, A, M or B. simply press and release the mode reset button.

1 ) When the mode reset button is pressed and released the exposure mode will be set to the normal program and "P" LED will light up in the viewfinder (Fig. 21). Any exposure adjustment and self-timer bulb settings on automatic will be cancelled. Any focus setting will reset to AF.

2) When the mode reset button is pressed and released, the metered shutter speed in the normal "P" mode is displayed in the data panel for 12 seconds. When the mode reset button is pressed and released after the self-timer is activated, the metered shutter speed is displayed in the data panel for one second: the self-timer is cancelled without exposing a frame and the automatic Exposure Bracketing (AEB) are automatically cancelled (if it was set).
The auto DX setting is restored to the + / - 0 EV level.

4. Focusing

The CP-9AF can be focused in any of the following modes.

1) Auto focusing.

2) Catch-in-focus.

3) Manual focusing by the use of a focusing ring. ( focusing aid)

(Auto focusing)
1) With the AF mode button held down, push the UP/DOWN button to phase in a single AF mode, "AF" (Fig. 22).

2) Lightly push the release button. Focusing will then be made automatically. As focus is achieved, a green LED " * " will     illuminate within the viewfinder (Fig. 23).

3) While the release button is held partially down, the " * " mark will remain lit and the focusing distance will be maintained. (Fig. 24)

(4) Once the auto focus lighting indicator in the viewfinder has been lit, the release button can be pushed all the way down to take a picture (Fig. 25).

5) After each exposure, the film and the frame counter are automatically advanced.4.butkus.org
 

(Focusing Indication within the Viewfinder)

* Do not attempt to turn or restrict the focusing ring during AF operation.

* For further details of the focusing operations, see pages 43 to 49.

* The shutter cannot be released unless the "*" mark is lit.
 

5. Unloading Exposed Film

When the film in the camera is fully exposed, the number in the film counter remains blinking for 12 seconds. All other LCD displays will disappear.

1 ) Slide the rewind switch protection cover in the direction of the arrow and push In the rewind button to
    rewind the film (Fig. 26).

2) During rewinding, the frame number counts backward showing how many frames are remaining to be rewound.

3) After rewinding, "O" appears blinking in the frame counter and the rewinding is automatically stopped.

4) Open the back cover and remove the film (Fig. 27). Do not open the back cover until the motor stops, even if "O" appears in the frame counter.
 

NOTE: If the motor should stop before the frame number reaches "O", do not open the back cover. Replace the batteries with a fresh set. When rewinding is completed, "O" will blink for 12 seconds. The shutter cannot be tripped until the rewinding operation is completed and the film cassette removed from the camera.4.butkus.org

6. Self-timer Operation

The CP-9AF is equipped with an electronic self-timer with a red LED and a unique "up to 90 minute" feature. The film is automatically advanced one frame after the exposure is completed.

1 ) Press the /time button to activate the self-timer for a 10 second delay (Fig. 28).

2) Focus and compose the picture and then depress the shutter release button.

The self-timer mode may also be cancelled by pushing /time button, as long as the self-timer is still in operation. In this mode, the 10 second self timer mode well be sustained indefinitely Cancellation will also occur by pushing the mode reset button, but in this case, the exposure mode and other settings will be reset to the normal exposure program, single AF and "O" compensated ISO settings.
If automatic exposures are used in conjunction with the self-timer, install the eyepiece cover to block any extraneous light rays that might adversely affect the exposure measurement (Fig. 29).

 
  • To set the self-timer operation for a particular length of time, push the UP/DOWN button to make the necessary setting while firmly holding the (clock)/time button down (Fig. 30).
  • Any length of time may be set in one second increments from 0-60 seconds and in one minute increments from 1-90 minutes.
  • The AF illuminator/self-timer LED starts blinking 10 seconds in advance of the shutter release and lights steadily for 2 seconds prior to the actual release of the camera's shutter
  • To check the film (frame) count in the middle of a self-timer operation such as may be required when the self-timer has been set for a long operation time, push the UP/DOWN button. The film count will be displayed on the LCD panel.
  • In the single AF mode, the self-timer operation will commence after the AF operation has been completed.

 


AUTOFOCUS OPERATION INSTRUCTIONS
Focusing Modes

The CP-9AF will focus in each of the following methods:

1 ) Autofocusing
2) Catch-in focus
3) Manual focusing (focusing aid)

1. Autofocusing
Either of two Autofocusing modes can be selected, depending on the situation at hand.

(AF <Single AF Mode>) This setting is for normal photography. The camera first focuses the lens on the subject, the AF lens operation ceases and a green "a" LED glows steadily within the viewfinder. As long as the shutter release button is held down lightly, the focusing will remain locked in. In this mode, no shutter release will occur until focusing is complete (Fig. 31).4.butkus.org

(CAF <Continuous A Mode>) In this mode, the AF follows the continued movement of the subject. It is best suited for shooting at a specific instant while tracking a moving target As long as the release button is held lightly down in this mode, the AF lens will continue to focus on the subject in response to any movement of the subject. The shutter may be released at any time regardless of whether the subject is in focus or not (Fig. 32).


(Locked Focusing Photography)
When the picture's subject is outside of the focus frame, follow the steps below for properly focused pictures.


1 ) Select the single AF mode setting with the AF mode and UP/DOWN buttons (Fig. 34).

2) Superimpose the focusing frame on the image which is to be sharply In focus. Lightly depress the release button to activate the focusing system (Check to make sure the "at" LED mark is glowing steadily In the viewfinder (Fig. 35).

3) Compose the photograph while holding the release button partially down and then push the release button all the way down to take a picture.

(Auxiliary AF Illumination)
Even in a dark environment that would normally cause focus difficulty, the CP-9AF automatically assists the auto focusing operation

 

1 ) Select the single AF mode (AF) (Fig. 36).

2) When the release button is partly depressed in a dark environment the auxiliary AF illuminator automatically emits a light to enable the auto focus operations to be completed.
 

  • The auxiliary AF illumination light is not activated either manual focusing mode (MF/CMF) or in the continuous AF mode (CAF) or with non auto focusing (C-AF only) lenses
  • Despite the addition of the auxiliary AF illumination light, accurate focusing Is sometimes impossible, such as when the target reflectance Is Inordinately low or when the distance is overly near or overly

 


2.Catch-in-Focus
In this mode, a focus range setting is made in advance. When the subject arrives at that distance, the shutter will automatically be released to take the picture.


1 ) Select the catch-in-focus (CMF) mode setting with the UP/DOWN button while holding the AF mode button firmly down (Fig. 37).

2) By turning the focusing ring, choose a shooting range setting (Fig. 38)

3) Compose the picture.

4) Push the release button all the way down and keep it there. (Use a tripod and cable release where required) (Fig. 39).4.butkus.org

5) As the subject arrives at the set range (the prefocused distance) the shutter will automatically be released to take the picture. (Fig. 40)
 

(Autofocus Defying Objects) Auto focusing accuracy can be diminished by low light levels, contrast, size and/or the physical configuration of the subject. In such cases the green " * " LED will blink in the viewfinder to alert you of the difficulty.
 

Subjects or Conditions
The following may not allow proper focus.

a. Low contrast subjects (with little differences between their light and dark areas).

b. Subjects lacking vertical lines.

c. Extremely small or finely detailed subjects.

d. Subjects that are intensely backlighted.

e. Subjects that extend from a near range to a far range.

f. Subjects with a continuous repeating pattern.

g. Fast moving subjects.

h. When using a soft focus or other special effects filters.

In any of the cases listed above, manually focus on the subject by using the matte area of the viewfinder screen.
 

3. Manual Focusing (Focusing Aids)

1 ) Select the manual focusing mode (MF) setting by pushing the UP/ DOWN button while holding the AF mode button down (Fig. 41).

2) Focus on the subject by turning the focusing ring of the lens to achieve the sharpest image of the subject in the matte area of the viewfinder screen (Fig. 42).
 

  • In the auto focusing modes (AF/CAF), do not attempt to forcibly turn the focusing ring while the auto focus system is functioning.
3) Push the shutter release button lightly down. As focusing is completed, the green "*" LED will glow within the viewfinder This confirms focus on the desired subject (Fig. 43).
