Installing Batteries

1. First, be sure to set mode selector dial (8) to
OFF position.

2. Turn battery compartment cover (33)
counterclockwise using a coin or something
similar

3. Two LR44 type alkaline batteries or two SR44
type silver batteries are used with this camera.

4. Place the batteries so that both positive (+)
sides are at the bottom of the compartment.

5. Replace the battery compartment cover and
turn it clockwise until it locks firmly.
6. Be sure to return mode select dial (8) to OFF
position to save the batteries from use when
storing or carrying this camera.

Battery Check
1. Advance the film by winding film advance lever (1).
2. Set mode selector dial (8) to your desired mode, AUTO or MANUAL position.

3. Press the shutter release button (2) partly while looking through viewfinder (23).
4. If two or three red LED dots light and can be seen in the viewfinder, battery condition is satisfactory. If no
red dot appears, the batteries need replacing or have been loaded incorrectly.
5. If the batteries are fully consumed, replace both with new ones.
6. If the film does not advance or shutter cannot be released, even though the batteries are new or loaded
correctly, set selector dial (8) to OFF position and lift off the label "RESET" adjacent to the film rewind button
(31). Then, use a ball point pen or something with sharp end and insert it into the hole where the label used to
be.

Loading Film

1. To open back cover (29), fold out the film rewind crank
then pull it out. When the back cover opens, frame counter
(3) automatically resets to "S".

2. Insert the film cassette into film chamber so that the
projecting end of the film cassette is downward. Do this in a
place away from direct sunlight.

3. Lift film rewind crank (13), and turn the crank carefully
while pushing it lightly downward until film cassette locks
onto the film rewind shaft (24). Return the film rewind knob
to its original position by pushing it down.

4. Insert the film leader in the groove of take-up-spool (28)
and place it so that the one of the lower row of film
perforations engages with the take-up spool's hook,

5. Now hook the film perforation holes on the sprocket
teeth. Operate film advance lever (1) carefully to advance
the film so that the film is wound properly. At this time, be
sure to align the film with film guide rail (22), if necessary,
using your fingers and being careful.

Shutter releasing cannot be expected without camera movement. For example, in photography using 1 35mm
focal length lens with full aperture, if slower shutter speed than 1/125 is set and it is indicated by LED lighting,
camera movement may occur when releasing the shutter. Use of tripod and/or remote shutter release control
cable is recommended.

Manual Exposure Photography

1. Advance the film and set the mode selector index
(9) of mode selector dial (8) to MANUAL. Then 1/125
shutter speed setting is obtained.

2. Looking through the viewfinder (23), two LED's
light and one LED blinks; one of lighting LED's is that
for "M", meaning manual exposure mode, and the
other is 1 25x, meaning that 1/125 shutter speed is
used. And another blinking LED indicates the shutter
speed recommended by automatic exposure system.
Therefore, the value of blinking LED may change
according to the change of the subject's luminance,
or by turning aperture ring (17).

3. Press the LED-up button (10) and the value indicated by LED will change upward; 125x, 250, 500 and 1000.
After 1000, then returns to the lower end, "B", then upward again, LT, 1, 2, 4. Stop pressing LED-up button
when the LED of desired shutter speed lights, the desired shutter speed is set for manual exposure photography.

4. Mean while, press the LED-down button (11), each time when the button is pressed, the value pointed by
LED will change downward; slower shutter speed is set.

5. The best way to find the appropriate exposure by manual operation is matching the shutter speed value which
the lighting LED indicates with the value which the blinking LED recommends.

6. It is also possible to get to the desired shutter speed quickly by pressing the LED-up/LED-down button
continuously. However, after getting near to the desired shutter speed value, it is recommended to press the
button quickly and repeatedly to get to the desired setting.





7. After the button is pressed quickly, the LED keeps lighting for approx. 10 seconds,

8. If the LED is set to LT manually, 2 seconds very slow shutter speed is set.

9. If the LED is set to "B", the mode changes to Bulb photography and no recommended shutter speed is given.

10. Before advancing the film, LED-up and LED-down buttons can be operated to set the shutter speed
manually. At this time, LED changes faster than after advancing the film.

11. The shutter speed once manually set is effective until the shutter speed is changed by operating the mode
selector dial or LED-up/LED-down button. Therefore, after once set the correct shutter speed to the subject, you
can repeat photographing with the same exposure without setting the shutter speed each time.

Bulb Photography in "B" Setting

1. Setting the mode into "B" (bulb), the
frame is exposed as long as the shutter
release button (12) is pressed. When
extreme slow shutter speed is necessary,
for example in night scene photography,
use of "B" setting is useful.

2. To set the mode to "B" (bulb), advance
the film and match the MANUAL on
selector dial (8) with mode selector index
(9).

3. While looking through the viewfinder (23), press the LED-up or LED-down button until the LED pointing
"B" at lower-left in viewfinder lights.

4. At this time, 2 LED's, "M" and "B" will I Tight.

5. For photography in this "B" mode setting, use of a tripod and/or a remote shutter release control cable is
necessary.

6. Once the mode is set to "B", photography in any other mode is impossible until mode selector dial or LED-
up/LED-down button is operated to change the mode.

7. In "B" mode setting, self-timer cannot be used.

Flash Photography

1. Advance the film and set mode selector
index (8) to MANUAL of mode selector
dial (9).

2. Look into the viewfinder (23) while
pressing the shutter release button partly
and confirm that two LED's light; one of
lighting LED's is LED for M, meaning
manual exposure mode, and the other is 1
25x, meaning that 1/125 shutter speed is
used. At this time, another LED will be
blinking to indicate the shutter speed

recommended by automatic exposure
system. However, the value of blinking
LED does not affect flash photography.

3. Now you can repeat the synchronized
flash photography 1/125 shutter speed as
long as the LED-up/LED-down button is
not pressed,

4. When using the automatic flash unit, set
the aperture to the f-stop specified in the
instruction manual of the flash unit.

5. When using kite usual flash unit, use the f-stop value obtained by the formula show below:

F-stop value (Fn) = guide number (ISO 100 m) /distance to the subject (m) X ISO/100
For further detailed, follow the instruction manual of the flash unit.

6. In special use of the flash unit, flash photography at slower shutter speed than 125X including "LT" and "B"
is allowed.

Use of Self-timer

1. The self-timer is very useful when you
wish to include yourself in a picture. Or, you
may use the self-timer instead of remote
release cable to prevent camera movement
in shutter releasing.

2. To use the self-timer, advance the film
and make sure that all settings, such as
composition, focusing, AK/MANUAL mode
selection, shutter speed, etc., are correct,
then press self-timer button (5).

3. Self-timer button has a self-timer display
LED in it. The self-timer LED starts
blinking when the self-timer button is
pressed, then after ten seconds the shutter
will release.

4. Approx. two seconds before releasing the shutter the self-timer display LED accelerates blinking to tell that
the shutter will be released soon.

5. Even after the self-timer display LED starts blinking, you may cancel use of the self-timer by pressing partly
shutter release button (2).

6. Turn the film rewind crank (13)
clockwise gently to properly tension the
loaded film. Stop turning the crank once it
becomes stiff, and close the back cover by
pushing it until it clicks. Now, return the
crank to its original position.

7. Set mode selector dial (8) to "MANUAL"
position.

8. Advance the film a couple of frames each
time releasing the shutter release button
until the frame counter reaches the
intermediate position between "O" and "2".
Check that film rewind knob (14) turns
while advancing the film as it means the
film advances properly.

Rewinding Film

1. When film advancing lever action feels
heavy, check frame counter (3). If all available
frames are exposed change the film with a
new one in a place away from direct sunlight
according to the following instructions:

2. Press film rewind button (31 ) and the
button is interlocked when pressed. If the film
was advanced exceeding the specified frames,
film advance lever may stop half way of
advancing the film. In such a case, never make
attempt to force it farther, leave the film
advance lever at halfway and press the film
rewind button.

3. Raise film rewind crank (13) and turn it clockwise. Once crank turning operation becomes lighter, it means
the film is fully rewound.

4. Raise film rewind knob (14) and pull it upward to open back cover (29). The film cassette can now be
removed. Be sure not to open the back cover before fully rewinding all the film.

Film speed Setting

1. Film speed is indicated on the outside of
film package, in the film instructions or on
the film cartridge.

2. Set film speed selector dial (15) so that
film speed index (16) indicates the value on
selector dial (15) corresponding to the film
used. For example, if film speed shown on
the film is ISO 100/21°, set the film speed
selector dial so that 100 on the dial matches
with the index.

3. Click points are provided at each step of
film speed on the film speed selector dial.
When setting the film speed, make sure that
it clicks.

Use of AE (Automatic Exposure) system

1. Advance the film and set mode selector
dial (8) so that "AUTO" on the dial matches
with mode selector index (9).

2. Press the shutter release button (2) partly,
while looking through the viewfinder (23)
and two LED's will light; the uppermost
LED "AUTO" means that the mode is now
set in AUTO exposure mode, and the other
indicates the shutter speed to be used when

fully releasing the shutter. For instance, if
the LED "AUTO" and LED pointing "250"
are lighting, then fully release the shutter
and 1/250 second shutter speed will be used
in auto exposure control mode.

3. If the LED pointing "OVER" is lighting, it
means overexposure resulting in
unsuccessful photography. Turn aperture
ring (17) to set a greater F-stop value.

4. When the LED pointing to "LT" is
lighting, extreme slow shutter speed approx.
2 to 8 seconds is used.

5. Even when setting the lens aperture to full
aperture, if the value of the LED lighting
indication is smaller than the value
corresponding to the focal length of lens,

Holding Camera

1. Hold the camera in the palm of the left hand so
you can turn focusing ring (18) easily with the
fingers. Gently place your forefinger on the
shutter release button and thumb finger on film
advance lever (1), and use the other three fingers
to hold the camera by grip (6).

2. Press your both elbows against your body
when holding the camera horizontally and press
left elbows against your body when holding the
camera vertically. To see the viewfinder, use
right eye while both eyes are open.

3. When releasing the shutter, stop breathing for a
moment to prevent camera movement.

Depth-Of- Field

1. When you are focusing on a given subject,
objects in the foreground and background will
appear acceptably sharp in the picture. The range
in which all objects appear acceptably sharp in the
picture is called the "depth-of-field". The depth-
of-field changes depending on the following
rules;

a) The greater the f-stop value is set with the lens used, the wider range of depth of field is obtained meaning
that the range in which all objects appear in focus extends.

b) The more distant from the camera the subject moves, the wider is the depth of-field.

c) The smaller the focal length the lens used has, the depth of field becomes the wider.

d) When you are focusing on a given subject, the depth of field in front of the subject is narrower than that
behind the subject.

2. To know the depth of field in your shooting situation,
use depth-of-field scale (19). The depth of field scale is
engraved with aperture index (20). For example, when
a lens of 50mm focal length is focused on a subject at a
distance of 3m with the aperture of f/8, the depth of
field is read as from 2.4m to 4.5m by reading the values
on the depth-of-field scale corresponding to the set f-
stop value "8". This means, in this shooting situation,
all objects within the range from approx. 2.4 to approx.
4.5m distance from the camera will be reproduced with
acceptable sharpness.

Infrared Photographyb- (Go digital)

1. As infrared rays have a longer wavelength than
visible rays, normal focusing point cannot be used
with infrared photography using an infrared film and a
red filter, To compensate for the difference between
normal focusing and infrared focusing, infrared
photography index (21 ) is used. The infrared
photography index is a small red dot positioned
adjacent to aperture index (20).

2. First secure focus in the normal ways without red
filter. Then, read off the subject's distance using the
normal distance scale on the focusing ring (18).

3. Align the value on the normal distance scale which was first read with the infrared photography index (21).
The example photo shown is for setting to a subject at infinity.

4. Be sure to use a red filter for infrared photography.

5. When using an infrared film, auto exposure cannot be used. Set the shutter speed and f-stop value manually
following to the instructions for the infrared film used.

Mounting and Removing the Lens

1. The type of lens mount for this camera is the "K"
mount, meaning that all other lenses with a "K" mount
can be mounted on this camera.

2. To mount the lens: a) Align the red mark on the
camera body with the red mark on the lens. b) Insert the
lens into the camera body fully then turn the lens
clockwise until it clicks, now the lens is interlocked
with the camera body.

3. To remove the lens from the camera body: While
pressing down lens release button (7) in the arrow
direction, turn the lens counterclockwise and the lens
can be removed.
