U Insertion of Batteries
The electronic system of your Pentax
PC35AF operates on two 1 SV mini batteries.
(Alkaline battery AAA)
(Caution: NiCd batteries can not be used.)
1. Open the battery chamber cover located at
the base of the camera by sliding it in the
direction of the arrow; use fingernail in the
groove to push the cover.
2. Fit two batteries into the chamber as
indicated—they should be fitted as shown.
Note the + and - markings provided.
3. Close the cover by pushing it back.
The lens protector may be opened by pushing
protector release in the direction of the arrow.
To close, push protector back, locking same in
its original position.
• With the protector closed, a safety device
prevents accidental firing of the shutter;
similarly, the flash pop-up release is also
locked at the same time.
• While holding the camera, even a slight
pushing-back of the lens protector would
activate the built-in safety device, locking the
shutter button. This is to avoid possible
vignetting.

Battery Status Check
After opening the lens protector, battery status
can be checked by covering the metering cell
with the hand as illustrated, and partially
depressing the shutter release button. The
ORANGE indicator will glow continuously,
accompanied by a beeping sound when
normal voltage is available: the lamp may be
seen in the upper section of the viewfinder.
Battery status is also known by another
method: in a brightly lit place, partially depress
the shutter button without covering the
metering cell with the hand, and if the GREEN
lamp lights, there is no problem with the
batteries.
• Insert both batteries properly according to
the indicated + and - markings.
• When replacing batteries, by type, brand,
new or old they should not be mixed, as by
doing so, poor results may be the outcome.
• It is recommended that the batteries are
removed from the camera if it is not used for
a long time. Leaving batteries in the camera
may result in acid leakage and possible
damage to the camera mechanism.
4 Film Speed Setting

1 Shooting
1. Center your subject within the auto focus
frame in the middle of the viewfinder.
2. After winding film, partially depress the
shutter button. Confirm, that the GREEN
lamp is lit in the upper section of the
viewfinder, which indicates a faster shutter
speed—suitable for hand-held shooting.
3. Continue to depress the shutter, and the
distance needle indicator moves with a
hissing sound. Further depressing will
complete picture exposure.
Should the lamp in the upper part of the
viewfinder be unlit, proper exposure is not
guaranteed.
• The auto focus control of Pentax PC35AF
operates for the subject within the auto
focus frame.
• Partly depress the shutter button, and the
needle indicator automatically moves along
the zone focusing marks, according to the
camera-subject distance. The zone markers
indicate the camera-subject distance
involved, as follows:
i=a distance of approx. 0.8m
(tl=a distance of approx. 1.5m
(infinity)
• When the needle indicator wavers in the
area of" £ ”, frame the subject so
that it is located within the short distance
compensation indicator.
• If.you hear a beep and the ORANGE lamp is
lit, it is a warning that the shutter speed is
too slow, causing possible camera shake,
and that insufficient light is being registered.
In this event, use of the flash is
recommended: refer to "Flash Photography"
found in the back of this operating manual.
• The auto focusing system is highly
accurate and reliable for ordinary
photographic requirements. However,
under certain conditions, the auto focusing
system may be confused. For example:
When the zone focusing marker and the
known subject distance indicate an
obvious discrepancy to a large degree, then
the subject distance cannot be accurately
measured by the electronic system of Pentax
PC35AF. Additional information and possible
remedies can be found under "Difficult auto
focusing subjects/situations" in this manual.

3. When film has engaged properly, confirm
that film is flat as illustrated, otherwise, raise
film rewind crank and turn it slightly in the
direction of the arrow to take up any slack-
then return the crank to its original position.
4. Close the back cover until it locks with a
click sound.
5. Film advance must be continued by means
of the advancing wheel until exposure
counter registers as illustrated. Advance
automatically halts when the first frame is
ready for exposure. You may now begin to
take photographs.
Recommended camera-subject distance with the system
For best possible results, operate at a camera-
subject distance of 0.7m to <» (infinity.)
Focusing cannot be satisfactorily accomplished
at the shorter distances of less than 0.7m.
Do not block the auto focus windows, lens.
metering cell, flash head, etc., found at the
front of the camera, with your hands (or
other objects)—it will interfere with the
light entering the camera, causing a false
reading.
It is important to hold the camera properly in
order to take blur-free photos. Practice holding
and operating the camera before inserting your
first roll of film.
The illustrations show the basic holding
positions. No matter which position you use,
be sure to grip the camera steadily with both
hands, hold the camera gently against the face
in a fixed position, and relax the rest of your
body in a secure posture. Brace the elbow of
the arm supporting the camera against your
body. Always press the shutter release button
gently.

X Exposure compensation
Care should be taken when photographing
people under back-light situations where the
sun or a bright sky or a window is behind the
subject, for the Pentax PC35AF auto exposure
system will tend to underexpose the subject.
To compensate for this type of situation, the
shutter should be released while simultaneously
keeping the exposure compensation button
depressed: the subjects will then be exposed
as close as possible to normal.

X Flash photography
Partially depress shutter button, should the g S|
beep warning activate and be accompanied by i
the simultaneous lighting of the ORANGE |_|
lamp in the upper section of the viewfinder, 1 1
this indicates a lack of sufficient light and the I pu«(i pow" ▼
possibility of camera shake, due to the slow
shutter speed involved. The incorporated flash jT
unit of the camera will help to overcome this ^
problem by compensating for the poor light. P Irjjn

the camera base — the flash will spring a full charge. When the flash unit is no
up into place and automatically begin to longer required, simply depress the head
charge. info 'he camera body: it will lock automatically
2. Prior to making exposures, allow the flash and return the camera to normal mode.
Utilize flash as a supplementary light source in taking photographs in the daylight;
In photographing a person/people appearing in the shade—under trees, heavy foliage, etc.,
without the use of flash-assisted synchronization, the face(s) of subjects appear somewhat darker
in the final photograph. Flash synchronization will help greatly in “lighting" up the dark areas of
the face, and rendering a pleasing overall photographic result to the subject.__
X Focus locking technique
When subjectfs) appear outside the auto
focus framing of the viewfinder, the main
subjects get out of focus: to remedy the
situation, the following focus lock
procedure is recommended;
1. Center your subject for focusing within the
auto focus frame of the viewfinder. Partially
depress the shutter button, which will freeze
the focus temporarily.
2. Confirm position of the zone focusing
marker indicator in the viewfinder.
3. While shutter button is partially depressed,
frame your picture and then release the
shutter.
• With the shutter button partially depressed,
focus control is frozen at the position of the
indicator within the zone focusing marker
area. Focusing will be unlocked when
pressure upon the button is released.
• After depressing the shutter button partially,
if you remove your finger from the shutter
button in order to stop taking a photograph,
the shutter button may remain depressed. In
that event, further depress the shutter button
and release the shutter. The button will then
return to the original position.
X Difficult auto focusing subjects/situations
Although the Pentax PC35AF auto focusing
system is extremely accurate and reliable,
certain difficult situations will create problems
for the system unless compensation is
provided. A common solution will be to focus
upon a subject located near the actual subject
being photographed, and freeze the distance.
Then move/position the camera to point con¬
sidered best for framing purposes.
Some typical problems which may be
encountered when the following subjects/
situations are within the viewfinder’s auto
focus frame:
1. N on-reflective objects—dark hair or a black
telephone—which possess poor reflective
qualities:
2. Wire-netting, latticework, and an iron
exercise-bar—all with minimal light
reflecting qualities:
3. When fluorescent lamps. T.V. sets, sunlight
coming through the trees, or strong
backlighting conditions are found in and
around the auto focus frame:
4. Glass panelling, mirrors, and/or a car
body—all possessing strong reflective
qualities:
5. Trains and cars and other fast-moving
objects;
6. Water jets, water surfaces, smoke, flame/fire¬
works., and other vaguely shaped objects.

• Automated flash control range
ASA/ISO 100 film .0.7 to 4m
ASA/ISO 400 film . 1.4 to 6m
• Number of cassette roll films possible
Approx. 100 flashes with a fresh set of
alkaline batteries, at normal temperature
and humidity.
Precautions:
• In flash photography, partial depressing
of shutter button will light the GREEN
lamp in the viewfinder. However, use flash
after confirmation of the flash ready lamp
before releasing the shutter.
• Should the shutter be released before the
flash ready lamp is lit. it may cause
underexposed pictures (darker results).
• The flash head must be pushed back into
the camera, when not required; if left as it is,
the batteries will continue to drain—
depleting them and shortening their life.
• In taking vertical photographs, the camera
should be held with the flash head
positioned upward: then, gently depress
shutter release.
X Self-timer
The self-timer is a useful supplementary aid in
combination with a tripod, whenever the
photographer wishes to include himself in the
picture—a family group photo or with friends.
1. The self-tirner may be set by pushing the
lever in the direction indicated by the arrow.
When the photograph has been taken with
the self-timer, the lever should be returned to
the original position.
2. Depress shutter release after the film has
been wound on with the thumb wheel.
The self-timer lamp (red) will light up—after
about 10 seconds, the shutter will be
released automatically. Approximately 3
seconds prior to the actual shutter release,
the lamp will begin to flash intermittently,
along with a simultaneous intermittent
electronic audible beep—indicating that the
shutter will be released in a few seconds.
This lamp also lights up for an instant when
the shutter is released during normal
photography.

X Attaching the neck strap
• Put one end of the neck strap into the hook
and tie it securely as illustrated. This strap
has been provided to offer handy portability
when carrying the camera.
X Soft cases
• As optional accessories, there are two
kinds of soft cases available for your
PC35AF, as illustrated. The type "S"
can contain only the camera, while
the type "L”, the camera fitted with
the PC35 Winder.

X Tips in taking good photographs
• Keep your back to the sunlight— with the
subject frontlit—and, depress shutter button
gently.
• Use the built-in flash often. Use it at parties,
family get-togethers, and other activities
where the lighting leaves much to be desired
for picture-taking. Avoid having highly
reflective background, when using flash, such
as glass or metals.
• The self-timer can add much pleasure to
your picture taking—use it often. The Pentax
PC35AF self-timer possesses a 10-second
delayed shutter release mechanism. Confirm
that the film has been wound, prior to setting
the self-timer.
• Make maximum use of the highly efficient
exposure compensation control to obtain
satisfying pictures under adverse
conditions such as people against a highly
reflective window, a bright sky, at the
seaside in fine weather, or even against a
background of snow, and many other similar
situations.

PREVENTIVE CAMERA MAINTENANCE
1. The Pentax PC35AF Is a highly developed precision instrument. Care must be taken to avoid
dropping the camera or striking it against a solid object—wall, bookcase, etc. Should this
, **recommended that the camera be taken to one of the nearest Pentax service
facilities for detailed inspection of any possible mechanical damage.
2. Dust, dirt and other foreign objects appearing on the lens, viewfinder or the auto focusing
windows should be removed as soon as possible for it will interfere with the performance of
your camera. It is recommended that a commercial lens blower or brush—available at camera
dealers be employed. This means is normally sufficient to accomplish simple cleaning.
Smudges, such as fingerprints, should be wiped off carefully by using a soft lens tissue or
cotton cloth impregnated with a mild lens cleaning liquid compound.
3. Solvents, such as thinners or alcohol, should not be used to clean the components—seepage
may cause irreparable damage to the special lens sealing and adhesive compound between
the glass.
4. If the camera gets wet, the camera should be wiped by using a soft, dry cloth. Following
lengthy seashore use, the camera should be carefully cleaned, again, using a soft cloth_
preferably, cotton, to remove the salt traces.
5. Cameras should not be subjected to high temperatures and humidity. For example; A car
interior or its trunk compartment is often subjected to a high degree of heat.
It is also possibly damaging to store your camera in a cabinet or closet containing certain
chemicals—insecticides, such as naphthaline—for any length of time.
6. Should the camera be subjected to immersion in water (salt water or fresh water), for example,
by being dropped info a lake or the ocean, the unit will malfunction: or, at worst, become
irreparable. It is recommended that the camera be brought into the nearest Pentax servicing
facility for a thorough inspection and possible repair/overhaul as soon as possible.
