FEATURES
When this camera is used with any SMC Pentax-A
or SMC Pentax-F lens, it offers four exposure
modes: Programmed AE, Aperture-priority AE,
Metered Manual and Programmed Auto Flash.
When the lens aperture is set to “A” position,
the Programmed AE mode can be used. When
the lens aperture is set to any f-stop other than
the “A” setting, the Aperture-priority AE or
Metered Manual modes can be used.
e When the conventional K-mount tens is used,
the camera operates in the Aperture-priority AE
or Metered Manual mode.
Programmed AE Mode
The camera automatically selects the most suitable
combination of shutter speed and aperture to obtain
correct exposure, simultaneously changing the
combination according to the brightness of the
subject. This mode is suitable for those who do not
want to be bothered by setting exposure controls.
Aperture-priority AE Mode
When you set the aperture manually, the shutter
speed is automatically adjusted according to
the brightness of the subject to provide correct
exposure.
This mode is suitable for taking pictures for which
the control of the depth of field is desirable, such
as portraits, etc.
Metered Manual Mode
The combination of shutter speed and aperture is
completely up to you. Guided by the meter
indication in the viewfinder, you can adjust both
controls to obtain proper exposure. If necessary,
deliberate over- or underexposure can be obtained.
Programmed Auto Flash Mode
When you use 8 Pentax dedicated auto flash on this
camera in its Programmed AE mode, the camera
automatically selects the proper aperture and shutter
speed to control flash output for proper flash
pictures.
e The camera does not operate unless the batteries
are properly inserted. Be sure to check how they are
inserted before operating it. Also check if the main
meter switch is set to ON or OFF.
e Most flashes made by others can be used on this
camera, but Pentax dedicated flashes will offer more
convenient functions.
Even if you use a flash with TTL auto flash
provision, this camera does not provide TTL auto
flash operation.
e When you use the accessories such as Extension
Tubes, Microscope Adapter, etc. that are mounted
between the camera body and lens, this camera
operates in the Aperture-priority AE or Metered
Manual mode. The Programmed AE mode cannot
be used.

This camera automatically sets the ISO film speed
of DX-coded film when it is loaded into the film
chamber. Therefore, you are recommended to use
only DX-coded film in this camera. (If non-DX film
is loaded the camera will automatically set the film
speed to 100, whatever film speed it may have; in
other words, the only non-DX film usable for this
camera is one with ISO 100.)
DX information panel
The film speeds which can be automatically set by
this camera range from ISO 25 to 1600, so be sure
to use the DX-coded film having a film speed within
this range.

FOCUSING
e 18
You can focus in three ways, with the split-
image, microprism, and/or matte field. To focus
using the split-image, turn the focusing ring
until the two images in the split-image circle at
the center of the focusing screen are perfectly
aligned. When using the microprism collar,
focus until the glitter disappears from inside the
collar. With the matte field, focus until the
image on the matte field appears sharp and
crisp.
Note: If the maximum aperture of the attached
lens is smaller than f/5.6 (for example, f/8 as in
the case of a long telephoto), it is easier to focus
on the matte field since the split-image and
microprism collar areas become much too dark
for satisfactory focusing.
Diopter adjustment for viewfinder eyepiece
People who wear eyeglasses due to myopia,
hypermetropia or presbyopia, sometimes find it
difficult to focus while wearing their glasses. In
this case, use the accessory diopter correction
lenses M (See page 42).
HOLDING CAMERA
Proper holding of the camera is essential to
minimize camera shake which causes blurred
pictures. Practice holding and operating your
camera before inserting your first film cartridge.
Generally there are three basic ways to hold the
camera. In any case, hold the camera tightly to
your face with your hands. The grips on this
camera will help you keep a steady hold on your
camera. Release the shutter gently while holding
your breath. Strong pressure on the shutter
release button may cause blurred photographs.
Take a secure, well-balanced posture without
straining yourself. The portion marked O in the
illustration should be drawn to your body. It is
a good idea to stabilize your body and the camera
using a tree, building wall, table, etc. For long
exposures or while using telephoto lenses, it is
recommended to use a tripod in order to reduce
camera shake to a minimum,
19e
SHOOTING IN PROGRAMMED AE MODE
e The camera is switched to the Programmed AE mode by just
setting the lens aperture to the “A” position while keeping the
Auto-lock Release Button on the lens.
e You can leave the shutter dial set at any position.
e Turn the main switch on, then press the shutter release button
half-way, and you will see ‘“P’’ and a shutter speed are displayed
in the viewfinder. As you further press the shutter button,
the shutter will be released.
e When the subject is too bright or dark, ''1000” or “1° blinks as
a warning. When 30" or smaller figures appear in the viewfinder,
there is a danger of camera shake. In such a case, use a tripod or
a flash. (For details, refer to page 38.)
21e
SHOOTING IN APERTURE PRIORITY AE MODE
e Set the aperture to the f-stop you desire by turning the aperture
19 ring. With the 50mm £/2.0 lens, you can set it anywhere between
£/2.0 to t/22.

until the blinking shutter speed disappears, so that correct
exposure can be obtained.
When setting shutter speed first
Set the shutter dial to the desired shutter speed. Rotate the aperture
ring until the shutter-speed display changes from a blinking speed to
a just glowing speed, namely, only one shutter speed is seen, so that
correct exposure can be obtained. If the display does not switch
from a blinking speed to a glowing speed even by turning the

EXPOSURE-MEMORY LOCK
Memory lock not used
The exposure-memory lock enables you to take
an exposure reading in the Programmed AE or
Aperture-priority AE mode, lock-in that reading,
move your position, and then take the picture
with the programmed reading. This is particularly
useful in high-contrast conditions, such as when
your subject is back-lit or has a dark background.
1. If you are taking a portrait, you can move in
close to your subject and take a close-up reading
of the face. To hold that reading, depress
the memory-lock button; this will hold
the reading for about ten seconds, simultaneously
making the shutter speed (LED) you are using
flicker in the viewfinder at a faster speed.

button half-way while the memory lock is in use,
the memory lock will be maintained or, in other
words, the exposure will remain the same.
When you wish to interrupt the memory lock,
just turn the main switch off.
Recompose your picture and shoot; the subject
will correctly be exposed. The memory lock will
automatically be cancelled as soon as you release
the shutter,
Cautions
When the Pentax dedicated auto flash is used on
this camera, the memory lock does not work,
If you accidentally depress the memory-lock
button with the camera in the Metered Manual
mode, the shutter speed set will meaninglessly
lock and flicker in the viewfinder.
SELF-TIMER
The self-timer is helpful for getting yourself into the photograph.
It can be set by sliding the main switch forward until the 'S.T.” is
visible, while depressing the self-timer lever.
As you cock the film wind lever and press the shutter release button,
the shutter will be released about 12 seconds later. The self-timer
lamp blinks to show the self-timer is working. About two seconds
before shutter release, the lamp will start to blink at a faster rate.
The self-timer can be cancelled even after it has started, by sliding the
main switch back to the original position.
* When you shoot at the B (Bulb) setting, the self-timer cannot be
used.
Caution: When using the self-timer, you keep your eye away from
the viewfinder, and light entering through the eyepiece can cause
errors in exposure. This can be prevented by sliding an accessory
viewfinder cap over the eyepiece, to shield the metering system
from extraneous light.
USING 100 § SETTING
When using a conventional clip-on-type flash on
this camera, set the shutter dial to 100 §
{1/100 sec.).
Caution: If non-Pentax flashes whose dedicated
runctions are claimed to work also with cameras of
other brands are used with this camera, they may
well cause malfunction and damage to the
electronic mechanism.
® 32
As illustrated, align “100 $” with the red-line
index. Set the aperture ring of your SMC Pentax-A/
-F lens to any f-stop other than A.
e When using a conventional flash, select an
appropriate f-stop according to the camera-to-
subject distance or the program of the flash.
(Refer to the instructions accompanying
the flash.)
e When using a sync-cord-type flash, use an
optional accessory: Hot Shoe Adapter 2P.
e This 100 4” setting can be used for non-flash
photography, but since the meter does not
function at this setting, you can in no way
make sure of correct exposure.

Depth of field is the area of acceptable
sharpness in front of and behind the point of
focus. The depth of field becomes progressively
greater as the lens opening becomes smaller.
The distance at which the lens is focused also
affects the depth of field: it increases as you get
further away. The focal length of the lens is
another factor to determine the depth of field.
The shorter the lens, the greater the depth of
field.

® be sharp in your pictures. By depressing the preview lever near the
od lens mount, you can close the lens down to whatever aperture you
| Io SR have set. You can then preview how much sharpness you will get in
your picture by examining the picture area on the ground glass. After
previewing your picture, if you release the preview lever, the lens will
return to full aperture for focusing. You cannot, however, preview the
depth of field with your camera set in the Programmed AE mode.
Note: Taking pictures with the preview lever depressed will result in
incorrectly exposed pictures.

INFRARED INDEX MARK
If you intend to take infrared photographs using
infrared film and R2 or 02 filters, it is necessary
to compensate for the difference between visible
light focus and infrared focus. As shown on the
right, note the subject-to-camera distance on the
lens distance scale as you focus through the
viewfinder and turn the focusing ring until that
distance setting aligns with the red infrared
index mark. The figure shows an example in
which the subject-to-camera distance is set at
infinity (99).
For details on exposure control, refer to the
instructions accompanying the film.

Remarks
This display indicates the brightness of the subject is beyond the metering range
in the Programmed AE mode. Releasing the shutter will result in incorrect
exposure,
Indicates the brightness of the subject is beyond the metering range, or that the
combination of shutter speed and aperture is beyond the coupling range, both
in Aperture-priority AE mode. In the latter case, you can change the aperture to
obtain correct exposure, In the former case, the flickering does not disappear
even if you change the aperture. Releasing the shutter with this display
appearing will result in incorrect exposure.
Indicates the brightness of the subject is out of the correct exposure range.
Change the shutter speed or aperture, and when the flickering disappears
and only one speed remains lit, you are ready to shoot.
Indicates the brightness of the subject is beyond the metering range in the
Metered Manual mode. The flickering does not disappear even if you change
the shutter speed and aperture. Releasing the shutter will result in incorrect
exposure,
When the exposure-memory lock is used, these LEDs flicker at a fast speed.
When batteries become exhausted, these LEDs flicker at a slow speed of once
per second.
e All these warnings are displayed by the flickering of LEDs in
the viewfinder,
e “Beyond the metering range” means the subject is too bright or
too dark to be measured with the camera's built-in meter,
e Beyond the coupling range” means the combination of shutter
speed and aperture is beyond the limit of use even when the
subject's brightness is within the metered range.
e For details on the metering/coupling ranges, refer to page 40.
e The symbol v»s+- in the table indicates flickering. When the
warning indicates beyond-the-metering-range/beyond-the-coupling-
range, the shutter speed flickers as fast as four times per second.
When the brightness of the subject is beyond the metering range,
take pictures in the following ways:
e When the subject is too bright, use an ND filter locally available.
e When the subject is too dark, it is necessary to use a flash or some
other lightings.

Fhe shutter-speed and aperture combination in
the Programmed AE mode is shown in the chart.
The red line represents the variation of shutter-
speed and aperture combination with an f/1.4
lens. Note that only the shutter-speed slows
down after the lens aperture reaches its limit of
£/1.4 in combination with a speed of approx.
1/30 sec. When you use a lens with a different
maximum aperture, the exposure program varies
the aperture and the shutter-speed in
combination until reaching the maximum
aperture of your lens. For example, with an f/2.8 -
lens the program varies the combination as shown
by the red dotted line. Note that only the shutter
speed changes after the maximum aperture is
reached. The fine red line in the Programmed AE
diagram indicates the Automatic Exposure control
range for a lens with minimum aperture smaller
than f/22, or for a film with ISO speed other than
100.
Metering Range and Shutter/Aperture
Coupling Range
The metering range means the range of subject
luminance within which the built-in exposure-
meter works to control exposure. The shutter/
aperture coupling range is that part of the metering
range within which shutter-speed and aperture
value can be combined for proper exposure control.
When you use a 50mm f/1.4 normal lens and
an 1SO 100 film, the metering range is from EV 1
(f/1.4-1 sec.) to EV 18 (f/16 -1/1000 sec.
or f/22-1/500 sec.). The range varies according
to film speed (ISO). The variation of the metering
“range is shown by slanting lines which shift ISO
ratings. The frame in the center shows the meter
and shutter/aperture control coupling range.
EV (Exposure Value)
EV represents a combination of the shutter-
speed and the lens aperture which is determined
by the film speed (1SO) and the brightness of
the subject.
âie
DIOPTER CORRECTION, MOUNT ADAPTER K, EYECUP P
Diopter correction lenses M which fit the eyepiece on your camera
are available. If you find it difficult to see the viewfinder image
clearly, choose any one of the eight Correction Lenses M of -5,
-4, -3, -2, -1, +1, +2, +3 diopters. Slide it into the eyepiece's
accessory groove. Before buying one, try it for yourself with the
lens attached to your camera.
Mount Adapter K
If you want to use any conventional Takumar screw-mount lens
On your camera it is possible by placing an optional accessory
called the Mount Adapter K between the camera body and the
lens. However, please note the following conditions when actually
taking pictures:
e Automatic diaphragm does not work due to difference in the
coupling system.
e Stop-down metering must be made.
e Automatic aperture setting with a Pentax dedicated flash is
not workable,
Eyecup P
The Eyecup P is attached to the viewfinder accessory groove.
When using such accessories as ‘’Diopter Correction Lens M,"
“Viewfinder Cap," etc., remove the Eyecup P from the camera.
PRECAUTIONS ON BATTERIES
» Incorrect usage of batteries causes such hazards
1s leakage, heating or explosions. Polarity markings
should be carefully checked while inserting
batteries. If either battery is erroneously inserted,
unexpected mishap may occur.
e Replace both batteries at the same time. Do
not mix battery brands and types, or old batteries
with new batteries.
e When not using the camera for long periods
of time, you should remove batteries from the
camera. Old batteries are apt to leak and
damage the battery compartment, Always keep
batteries out of the reach of children.
e Never break, recharge, or throw used batteries
into fire as a precaution against explosions.
e Batteries should be kept warm in cold climates
to prevent lowering of performance.
e Keep spare batteries on hand for convenience
in photographing outdoors or while traveling, etc.
e One set of alkaline batteries should last about
six months and one set of silver-oxide batteries
about a year, both with average use.
e When keeping the camera in a bag or case, be
sure to turn the main switch off to avoid the
unnecessary consumption of battery power that
may result from accidentally releasing the shutter.

TAKING CARE OF YOUR CAMERA
e 46
Y our Pentax camera is a sophisticated, precision
instrument built to give long-lasting, reliable service.
It will serve you well if you treat it right, with
proper handling and reasonable care. The major
causes of damage are:
1. Dropping or banging can damage the camera
in many ways.
2. Water damage, particulary if the camera is
submerged in salt water. Cameras are not water-
proof! They must be protected from salt spray
at the beach, splashing of any kind, and shielded
from the rain. If your camera does get soaked,
wipe it dry immediately and rush it to a Pentax
service center.
3. Dirt and sand can cause serious damage to the
shutter and other moving parts of the camera.
Your camera needs periodic cleaning to keep it
operating properly. To remove dirt and dust, you
need lens-cleaning fluid, lens-cleaning tissues, bulb-
type ear syringe, camel's hair brush, etc. Never use
a solvent such as thinner or alcohol.
4. Humidity and extremely high/low temperature
should be avoided. Keep your camera out of direct
sunlight, car trunks, and glove compartments.
Shooting outdoors in winter presents a problem
since batteries won't function if they get too cold.
In cold weather carry your camera under your coat
or jacket to keep the batteries warm. The
temperatures at which this camera should function
properly are approx. 50 ° ~ -10°C. Sudden
changes in temperature will often cause moisture
to condense inside or outside your camera. This is
a possible source of rust, which may be extremely
harmful to the mechanism. Thus, sudden
temperature changes should be avoided as much as
possible. As a guide, a temperature change of 10°C
should be allowed to take place gradually over a
period of at least 30 minutes. If this is not possible,
keeping the camera in its case or bag will help
somewhat in minimizing the effects of a rapid
temperature change.
5. Vibration experienced when you are traveling
in a car, plane, or ship, can cause screws to loosen.
To minimize this problem use foam-rubber padding
about one inch thick to line the bottom of your
camera bag.
6. When mounting your camera on a tripod, make
sure the tripod screw is no longer than 5.5mm,
which is the depth of your camera's tripod socket.
If you use a longer screw, you will possibly
puncture the tripod socket, after which the camera
will not function properly.
7. Always put a lens cap or body mount cap
whenever the camera is not in use. To avoid an
accidental damage to the shutter curtain by
sunlight, do not direct the camera to sun for a long
period of time.

All Pentax cameras purchased through authorized
bona fide photographic distribution channels are
guaranteed against defects of material or work-
manship for a period of twelve months from date
of purchase. Service will be rendered and defective
parts will be replaced without cost to you within
that period, provided the equipment does not
show evidence of impact, sand or liquid damage,
mishandling, tampering, battery or chemical
corrosion, operation contrary to operating
instructions, or madification by an unauthorized
repair shop. Because the tolerances, quality, and
design compatibility of lenses other than Pentax
lenses are beyond our control, damage caused by
use of such lenses will not be covered by this
warranty policy. The manufacturer or its
authorized representatives shall not be liable for
any repair or alterations except those made with
its written consent and shall nog be lable for
damages from delay or loss of use or from other
indirect or consequential damages of any kind,
whether caused by defective material or work-
manship or otherwise; and it is expressly agreed
that the liability of the manufacturer or its
representatives under all guarantees or warranties,
whether express or implied, is strictly limited
e 48
to the replacement of parts as hereinbefore
provided. No refunds will be made on repairs
performed by non-authorized Pentax service
facilities.
Procedure During 12. month Warranty Pernod
Any Pentax which proves defective during the
12-month warranty period should be returned to
the dealer from whom you purchased the equip-
ment or to the manufacturer. If there is no
representative of the manufacturer in your
country, send the equipment to the manufacturer,
with postage prepaid. In this case, it will take
a considerable length of time before the equip-
ment can be returned to you owing to the
complicated customs procedures. If the equipment
is covered by warranty, repairs will be made and
parts replaced free of charge, and the equipment
will be returned to you upon completion of
servicing. If the equipment is not covered by
warranty, regular charges of the manufacturer or of
its representatives will apply. Shipping charges are
to be borne by the owner. If your Pentax was
purchased outside of the country where you wish
то have it serviced during the warranty period,
regular handling and servicing fees may be
charged by the manufacturer's representatives in
that country. Notwithstanding this, your Pentax
returned to the manufacturer will be serviced
free of charge according to this procedure and
warranty policy. In any case, however, shipping
charges and customs clearance fees are to be
borne by the sender. To prove the date of your
purchase when required, please keep the receipts
or bills covering the purchase of your equipment
for at least a year. Before sending your equipment
for servicing, please make sure that you are
sending it to the manufacturer's authorized
representatives or their accredited repair shops,
unless you are sending it directly to the manu-
facturer. Always obtain a quotation of the service
charge, and only after you accept the quoted
service charge, instruct the service station to
proceed with the servicing.
This warranty policy does not apply to Pentax
products purchased in the U.S.A., U.K., or
Canada. The local warranty policies available
from Pentax distributors in those countries
supersede this warranty policy.
