Simplified Guide (basic level)
A. Battery Installation

1) Insert a pointed object such as a ball-point pen into the battery cover release hole on the bottom of the camera and slide it in the direction indicated by the arrow to open the battery compartment. (Fig. 1)

2) Place the battery correctly in the battery compartment in accordance with the marks inside and close the cover.  Use a 6 V lithium battery "2CR-5". (Fig. 2)

B. Battery Check Slide the flash-up button (main switch) to the "ON" position. If the film counter and battery check mark are lighted on the LCD panel at this time, power is being supplied to the camera circuitry. The marks will stay lighted for 30 seconds until an automatic power shut-off system goes into effect. (Fig. 3)

NOTE:
* When either of the following occurs it means that the battery condition is too low for continued use and
should be replaced with a new one.

— The battery check mark is blinking.

— Nothing appears on the LCD panel.

* Battery life: Approximately 36 24-exp rolls, using 50% flash (Chinon laboratory testing)

(Memory Backup System) This camera uses a condenser as a memory backup. Therefore, even without a battery, the memory function will work for two to three hours. After that, the film counter will go back to "0" even in the middle of a roll of film. Replace the battery as quickly as possible to avoid losing the correct frame number.

C. Setting the Film Speed

Films with DX coding. (Fig. 4)4.butkus.org
If a film with DX coding is used' the film speed will be set by the camera automatically Film can be used with ratings from ISO 25 to 1600.

NOTE:
* For reversal (Slide) film, please use ISO 25, 50, 100, 200, 400, 1000 or 1600.

- For film without DX coding, the camera is set automatically at ISO 25. Only use non-DX film with an ISO 25
  rating.

* Please keep the camera's DX contact points and the DX information panels on the film cartridges clean.

D. Automatic Film Loading

The film should be loaded into the camera carefully, without being subjected to direct sunlight.

1 ) Open the back cover by pushing the back cover release button in the direction of the arrow (Fig. 5)

2) Insert the film cartridge and pull out the film so that the trimmed end lines up with the film tip mark. Make sure
     that the film lies flat between the film guides.

3) Close the back cover. (Fig. 6) The film will be advanced automatically until the counter on the LCD
     panel shows "I".

NOTE:
* If the frame counter on the LCD panel is blinking "0" after the back cover has been closed, it means that the
   film has not been loaded correctly. Open up the back cover and insert the film again correctly

The length of the film should not be too long or too short. If too much film was pulled out of the film cartridge, then rewind some of it back into the cassette so the end of the film reaches the film tip mark on the back of the camera.

When the back cover is opened, do not touch the inside of the mirror housing.

E. Holding the Camera

Hold the camera in such a way that your elbow is touching your body securely to ensure camera steadiness and to avoid camera shake. (Fig. 7)

Hold the camera so that fingers carrying straps, etc. will not cover any part of the flash unit, lens, or the AF measuring windows.

Press down the shutter release button gently. When the telephoto lens is in use, be careful to prevent any camera movement.
 

F. Viewfinder Information

1 ) AF OK signal.

When blinking, this indicator warns that the camera to subject distance is too close for proper focus. The
camera shutter cannot be released in the single or continuous shooting modes if this condition occurs.

2) Flash Ready Signal

When the flash is fully charged, the light will glow steadily. While the flash is recharging, the same light
will blink until the flash recharging is completed.

3) Autofocus Frame/Microprism

This area should be pointed directly at the picture's subject to assure pinpoint focusing accuracy In the macro
mode, the microprism will assist in achieving sharp focus.

G. LCD Panel Display

1 ) Frame counter

2) Self-timer

3) BLC (backlight control)

4) Battery check

5) Multiple exposure
 

H. Controlling the Image Size by Using the Zoom
The through-the-lens reflex viewing of the camera enables the image to be viewed exactly as it will result on the picture. Use the zoom lever to adjust the desired image size.

 
1 ) Telephotography When a telephoto perspective is desired, move the zoom lever in the direction of the tele (80 mm) position. (Fig. 8)

2) Wide Angle Photography When a wide angle or panoramic view is required move the zoom lever in the direction of the wide angle (35 mm) position. (Fig. 9)4.butkus.org
 
 

I. Autofocus Shooting 1 ) Place the AF mode button to the single AF mode position for most forms of photography (Fig. 10)

2) Position the camera so that the object is set within the autofocus frame of the viewfinder. (Fig. 11)

3) Press the release button gently. Focusing is measured and set automatically. Once the focus has been completed, the "AF OK" mark in the viewfinder will light up and the object in the autofocus frame will be visible in sharp detail. This is a visual confirmation that the subject will be correctly focused on the picture. Press the shutter button all the way to take the photograph. (Fig. 12) When the camera-to-subject distance is too close, the AF mark in the viewfinder will blink. The camera should then be manually shifted into the macro mode or the distance between the camera and the subject must be lengthened. (Accurate AF measurement is from 0.85 meters (33.5~) to infinity. When using the camera, the shutter cannot be released until the lens has been properly focused. (Fig. 13) The following conditions or subjects may not be properly focused.


NOTE: For proper focusing, make sure that the subject completely fill the entire area of the viewfinder focusing zone. When focusing on a subject that cannot fill the entire area of the viewfinder focusing zone, position the subject at the lower right corner of the focusing zone (Fig. 14). This is the area in which the infrared ray is most precisely controlled. Water surface, car bodies, glass and similar objects which easily reflect light. Also, objects viewed through glass windows or wire netting, etc.
 
 

J. Automatic Film Rewinding


1 ) When the entire film cassette has been used, the film will automatically start to rewind within two to three
seconds. (Fig. 14)

2) While the film is rewinding, the counter will count back wards. When the film is entirely rewound, the rewind
motor will stop automatically.

3) Check the frame counter on the LCD panel to make certain that the film counter shows "0" before opening
the back cover.

(Rewinding a partially exposed roll of film)

If a film must be removed before it has been completely used, press the manual rewind button located next to the back cover release button on the side of the camera. Use a ball-point pen or a similar object which is not too sharp.

Rewinding will begin automatically (Fig. 15)

NOTE:
After the film is rewound if the frame counter still does not return to "0"' but the frame number is blinking,
press the manual rewind button again.4.butkus.org

K. Attaching the Hand Strap and the Lens Cap

The hand strap and the ions cap can be attached to the camera as shown in the diagram. (Fig. 16)

Applied Use

A. Continuous Shooting

It is possible to take a maximum of three continuous pictures if the camera is in the continuous AF mode (cons) and the shutter release is kept fully depressed.

1 ) Set the AF mode button to the Continuous AF Mode (Fig. 17)

2) Press the shutter release button gently. The automatic focus will operate and the subject will come into focus.
    The AF "OK" signal in the viewfinder will light up. (Fig. 18)

3) After confirming that the AF "OK" signal is lit, take the picture by pressing the shutter release button all the
     way down.

4) Keep continued pressure on the shutter release button.  When three frames have been exposed, the camera's film advance will automatically stop. (Fig. 19)

B. Auto Focus Modes

(1 ) Single AF Mode (S) The setting is ideal for general picture taking as it incorporates a built-in focus lock and subject too close warning. When the shutter release button is gently pressed, the autofocus system operates and the subject comes sharply into focus. Sustained pressure on the release button will maintain a focus lock. The shutter will not operate until the camera has completed the autofocusing procedure.

(2) Continuous AF Mode (C) This mode allows the camera to continually refocus as the subject moves closer to or further from the camera. The shutter will not operate until the camera has completed the autofocusing procedure. Pictures may not be in exact focus at times, especially for subjects that are moving very rapidly.
 
 

NOTE: When focusing in the Continuous Shooting mode, always depress the shutter release button gently to its halfway position. Make sure that the AF OK LED is lit. Never depress the Shutter Release all the way until the AF OK LED is lit. Otherwise, the following may occur:

* In the Continuous Shooting mode if the shutter release button is fully depressed before the AF OK LED is lit, the shutter may be released even if the focusing has not been completed.4.butkus.org

* In the Continuous Shooting mode, if the lens is positioned at the minimum focus position and the shutter release button is fully depressed while the AF OK LED is blinking, the shutter will be locked. If this happens, position your finger halfway on the shutter release button so that the camera will be able to focus properly.

C. AF Lock (Prefocus) and Cancellation

When the main subject is located "off-center" in the view finder, or when it is difficult to focus on the subject, the
focus lock is invaluable. (Fig. 20)

1 ) Set the single/continuous advance switch to the single AF mode. (Fig. 21 )

2) Look into the viewfinder and point the autofocus frame on the center of the subject that is to be in focus. Press down gently on the shutter release and confirm that the AF signal in the viewfinder (green) lights up. (Fig. 22)

3) Without losing tension on the shutter release button, recompose the picture in the viewfinder and then take the photograph by pressing the shutter release button all the way down. (Fig. 23)


NOTE:
* The photo lock feature can be cancelled by removing your finger from the shutter release button. Thus, you
can repeat this technique a number of times without having to take a picture.
 

D. Exposure Correction (backlight control)

When the main subject has less light falling upon it than the surrounding area, the subject may be underexposed or silhouetted. The backlight control compensates for the light imbalance and enables the subject to be more favorably exposed.

When the backlight control (BLC) button is pressed, the BLC indicator will appear in the LCD panel. When the shutter release button is depressed the exposure will be corrected automatically. (Fig. 24)

NOTE:
The exposure correction will be cancelled automatically after the picture has been taken. The backlight compensation can be cancelled without taking a picture by either pressing the backlight control button again or by
closing the main power switch.

When taking a photograph at close distances, it is recommended that the daylight flash sync function be
activated.
 

E. Macro Photography

Fascinating macro close-ups of subjects can be taken at distances between 50 to 85 cm (19.5" to 33.2").

1 ) Set the zoom lever to the tele (80 mm) position. After pressing the shift button rotate the zoom lever to the macro focusing area. (Fig. 25)4.butkus.org

2) The lens must be manually focused. The camera's autofocus system is inactive when the lens system is shifted into macro. Ensure that the camera-to-subject distance is within the macro parameter and then focus by using the zoom lever to achieve sharp focus. (Fig. 26)

3) Press the shutter release button all the way down to take a picture. Move the position of the camera backward and forward as needed to assist in focusing the subject. The camera's flash system operates at a fairly bright level. Some light colored objects may tend to be overexposed in the case of macro photography. After completing any desired macro photography, be sure to return the zoom lever to the normal 35-80 mm picture taking position, since the camera's AF system will not function in macro.
 
 

F. Multiple Exposures

By pressing the multiple exposure button, the film will not advance automatically after taking a picture. Up to three scenes may be photographed (multiple exposures) on the same frame.

Multiple (Two) Exposures in Single Mode

1 ) Set the Single/Continuous Switch to the SINGLE position. (Fig. 27)

2) Press the multiple exposure button. The LCD's counter frame blinks, indicating that the multiple
    exposure mode is activated. (Fig. 28)

3) Take the first photograph by pressing the shutter release button. The film will not advance at this time.

4) Remove your finger from the shutter release button and decide on the composition of the second picture, to be recorded on the same frame as the first picture. When the second image's composition has been selected, press the shutter release button to take the second picture. At this point the film will advance the counter frame will stop blinking and the multiple exposure mode is automatically cancelled.

Multiple Exposures (Three) in Continuous Mode 1 ) Set the Single/Continuous Switch to the CONT. position. (Fig. 29)

2) Press the multiple exposure button When the counter frame on the LCD panel starts to blink, the multiple exposure mode is activated. (Fig. 30)

3) After composition has been determined, press and hold the shutter release button and take the photograph. (Fig. 31)
 

NOTE: * 1 Reversal (slide) film is not recommended for use with the multiple exposure feature. Prior to developing and printing the film, the photofinisher should be advised that multiple exposures have been taken. Otherwise, the negatives may not be printed, or printed improperly The multiple exposure technique is suitable for capturing fireworks displays or night scenes or when using the flash in a dark area. In daylight, it may result in overexposed negatives.4.butkus.org

* 2 Single and Continuous Multiple Exposure Modes The multiple exposure mode will remain in effect after the first shot has been taken, even if the main switch has been set to "OFF". The next picture will be superimposed on the first picture because the film will have not advanced.

* 3 Continuous Multiple Exposure Mode In this mode, all three shots will be taken in rapid succession. Your finger should only be removed from the shutter release button upon the completion of the third shot.
 

G. Self-timer

The camera has a built-in electronic self-timer It enables everyone to get into the picture and also helps to avoid
camera shake in slow shutter speed situations, provided the camera is placed on a tripod or other firm surface.

1 ) Compose the picture using the reflex viewfinder

2) Press the self-timer button. The self-timer marking will appear on the LCD display panel as confirmation that
    the self-timer mode has been activated.

3) Press the shutter release button. The picture will be taken about ten seconds after the self-timer indication
    on the front of the camera lights up. The LED will start blinking about three seconds before the shutter is
    released to provide an advance warning of the shutter release.

(Self-timer Cancellation)

The self-timer can be cancelled by pressing the self-timer button again or by setting the main switch to "OFF".
The self-timer will be cancelled automatically if the shutter release is not pushed within 30 seconds of originally activating the self-timer system.

During self-timer operation the sensor flash will be activated exactly as during normal use. Please consult the
automatic sensor flash mode' off flash mode, and fill in flash mode sections of this booklet for other techniques.
 

Flash Tips for avoiding red eye in color flash pictures

Sometimes peoples eyes may appear red in color flash pictures. The red is caused by reflections from the retina of the eye. Although your camera is designed to reduce this effect by placing the flash as high as the camera design allows this effect may be still evident especially in young subjects who have a light complexion and blue eyes, or when your subject is in dimly lighted surroundings. To minimize the problem, turn on additional room lights or have your subject look directly at one of the lights' causing the pupils of the subject's eyes to contract slightly.4.butkus.org
 

H. Flash Photography

(Automatic Sensor Flash Mode)

The camera is designed to measure ambient light intensity and then activate and fire the built-in flash when needed. If the "lighting bolt " mark in the viewfinder lights up or blinks when the release button is pressed gently, the automatic flash mode is in operation. (Fig. 32)

The "lighting bolt " flash mark will light when the shutter release is depressed in the following cases:

1 ) When the mark glows constantly, the flash is fully charged and the subsequently exposed picture will be
      exposed by electronic flash.

2) When it is blinking, the flash is in the midst of charging.

NOTE:
In the single shot mode, the shutter cannot be released. In the continuous mode, pictures can be taken prior to the flash being fully recycled.

(Effective Flash Distance)
 
ISO 35 mm  80 mm
100  0.85~ 4.2 m 
(3 - 13 feet)
0.5~ 2.7 m
(1.5 - 7 feet)
400  0.85~ 8.3 m
(2.5 - 13 feet)
 0.5~ 5.1 m
(1.5 - 15 feet)

 

NOTE: When taking color flash pictures, people's eyes sometimes appear red. The red is caused by the reflections from the retinas in the subject's eyes. To minimize the reflection, turn on the room lights and have the subject face the lights.
Position the camera at an angle to shiny objects like windows or mirrors. Otherwise light from the flash can reflect from the shiny surface and produce a bright spot on your photograph.
(Off-Flash Mode) Although the camera fires the flash automatically in accordance with the brightness of the surrounding lighting conditions, there are times when it might be preferable to take a picture without flash to capture a special mood. Slide the flash mode switch downward and release the shutter release button while keeping the switch in that position. The flash unit will not fire and the resulting image will be exposed with available light only. When this mode is utilized, the flash symbol will not be illuminated in the viewfinder (Fig. 33)

(Fill-in Flash Mode <daylight sync>) Under some available light conditions (deep shade or backlit situations) a picture may result where the subject is too dark. The use of the flash for daylight flash fill will enhance the picture tremendously under these conditions. Fill flash is achieved by sliding and holding the "flash mode switch" upward and then pressing the shutter release button. The flash symbol in the viewfinder will light as a confirmation that the daylight flash system has been activated. (Fig. 34)

NOTE: When using flash-off or fill-in flash, shutter speed may be as slow as 1/4 sec. (Slow Shutter Program), use of a tripod is recommended in low light situations.
 

I. Filter and Hood

Use the filter ring which is designed specially for the camera. It enables 62 mm filters to be used with the camera.  Attach the filter after the adapter ring has been fitted to the camera. When taking photographs in back lighted conditions, use of the lens hood exclusively designed for this camera is suggested.
The lens hood has two flanges on its circular mounting base. Align these horizontally with the front of the lens on
the camera and rotate clockwise until the hood is firmly seated in place. Remove the flash for flash photography to assure full frame flash coverage.

NOTE:

When filters such as multi-imaging, etc., are used with the camera, slight vignetting may appear in the corners of the pictures.

J. External Flash Unit

The external flash unit (Auto GS-320) can be used to extend the effective flash range of the camera when using
ISO 100 or 400 negative films. Using the Auto GS-320 is recommended when the subject is beyond the effective flash range of the camera's built-in sensor flash. The Auto GS-320 flash unit will also permit bounce flash photography.

How to operate:

1 ) Attach the Auto GS-320 to the camera and turn the slave switch on the flash to "ON".

2) For ISO 100 negative film, select the automatic position of A1 (A2 for ISO 400 negative film). Set the zoom head of the flash according to the following table and the picture can be taken.

(0.85-13 m; 2.8'-43')
(0.85-13 m,2.8'-43')
(0.85-10 m, 2.8'-33')

 

Using the optional slave unit (SE-520)
With the optional slave unit (SE-520), a hot shoe type automatic flash unit having an F number setting can be used as an external flash unit with the camera. The effective flash range can be calculated with the following formula. Effective range = Guide number - divided by - F=4.1 and 6.4 for 35 mm and 80 mm zoom lens settings respectively.

K. Tele Converter
Chinon offers an optional tele converter for the camera which will extend the focal length of the telephoto distance to 105 mm. For its operation, the instruction booklet of the tele converter should be referenced.
L. Eyepiece Cover
The lens cap of the camera is designed to slope on to the camera's eyepiece. When the self-timer is operated, the lens cap should be attached to the eyepiece (Fig. 35) to avoid exposure errors due to stray light entering the camera body
M. Care of the Camera The camera is a precision photographic instrument. When used with care it will provide years of trouble-free service. Protect your camera from dirt, rain, dampness and excessive heat. Avoid touching the lens. To clean the lens, wipe it gently with a soft lintless cloth or tissue. Do not use eyeglass tissues as they might damage the lens coating. Do not open and touch the inside of the camera as possible high voltage in the flash circuitry can be dangerous. When the camera will not be in use for a long period of time, turn off the main switch and store in a well ventilated, cool, dry place.
