eli
The ASA film speed rating of all 35mm films is given in the data
sheet packed with each roll of film. The higher the ASA number, the
more sensitive the film is to light.
To set the index, first make sure that the exposure factor dial is set
at “1x”. While depressing the ASA ring lever @, turn the ring until
the ASA number of your film is opposite the orange index mark.
As a reminder of what type of
film is in your camera, tear off
the top of film box and insert it
into the Memo Holder on the
back cover of the camera.
REMEMBER to set the dial at
“1x” for normal exposure.
The scale (4x, 2x, 1x, 1/2x, 1/4x) indicates exposure factor. Y ou get
“normal” exposure at 1x, while 1/2x and 1/4x automatically
program the camera to deliver one half and one fourth the amount
of light to the film. The 2x and 4x settings automatically double and
quadruple the light reaching the film.
Use this control only when necessary to give intentional over- or
under-exposures while operating on "AUTOMATIC." For example,
set the dial at 4x or 2x when shooting against the light, and at 1/4x
or 1/2x when shooting against dark backgrounds. In addition, the
dial can be set between the indicated positions to achieve more
specific exposure control.

This is a rough guide to aquaint you with the automatic shutter
operation. As you get used to it, you will develop your own
vardsticks for aperture pre-selection depending on your subject and
the lighting conditions.
The shutter speed is automatically determined, within the range of 8
to 1/1000 sec., depending on the amount of light passing through
the aperture and the speed of your film.
Set the shutter speed dial at "AUTOMATIC" for
automatic electronic shutter operation. {When set
on “AUTOMATIC”, the exposure system is an
aperture-preferred system. For a shutter-speed-
preferred system, see MANUAL SHUTTER AND
LIGHT METERING, p. 16.)
The electronic shutter of the K2 works
automatically between 1/1000 and 8 sec. The
black numbers seen in the viewfinder refer to
fractions of seconds — 1/60, 1/125, etc. The white
numbers — 2, 4 and 8 — refer to 2 sec., 4 sec., and
8 sec.
After cocking the rapid-wind lever, press the
shutter button slightly to switch on the electric
circuit. The meter needle in the viewfinder will
indicate the shutter speed which the camera has
selected. If the needle does not drop from 1000,
close down the lens diaphragm one or more stops.
If the needle still does not move, push the battery
check button. When the batteries are worn out, the
electronic shutter will not function. Moving the
shutter speed dial to 1/125 sec. will allow you to
continue photographing. {You will have to
determine aperture settings without the light
meter. Packed in with most types of 35mm film is
a data sheet of suggestions for determining the
correct exposure in a variety of situations.) But you
should carry spare batteries, and replace worn-out
batteries immediately.
14e
e15
Depress the shutter button completely to shoot. As
long as the rapid-wind lever is not closed
completely — that is, as long as it is returned to
its slightly open, pre-advance position — the meter
will stay on and the needle will automatically
indicate the speed for the next shot. Once the
rapid-wind lever has been completely closed, the
meter will be activated only as long as you are
depressing the shutter button.
To prevent accidental shutter release, lock the
shutter button by moving the lock lever €) so that
the “L”' becomes visible.
NOTE: If you should happen to depress the shutter
button, while the shutter dial is set at
“AUTOMATIC” and the lens cap is on, the reflex
mirror may fail to drop back down into place.
To bring the mirror down, simply move the shutter
dial off “AUTOMATIC.”
MANUAL SHUTTER AND LIGHT METERING
Your K2 camera is unique: it also offers manual
electronic shutter operation over the full 1/1000
~ 8 sec. range. This operation is useful for
shutter-speed-preferred shooting situation — when
you need full control over the shutter speed. To
use any of these speeds, depress the shutter dial
lock pin O , and turn the shutter dial from
AUTOMATIC to the desired speed setting.
When you are operating the shutter manually, the
blue needle in the viewfinder will indicate the
shutter speed you have selected. Depress the
shutter button slightly and turn the diaphragm ring
until the black meter needle matches the blue
needle.
16e
While viewing through the
viewfinder, turn the focusing
ring until your subject comes
into sharp focus. Depending on
the type of focusing screen your
camera has, there are two ways
of doing this.
e17
Split-image focusing system
A cross-microprism focusing
system consists of a Fresnel lens,
made up of many concentric
rings, with a microprism center
underneath the ground glass.
With this system, when your
subject is in focus, the image in
the microprism center will be
sharp. If your subject is not in
focus, the microprism will break
the image up into many small
dots.
A split-image focusing system
consists of a Fresnel lens with a
horizontally divided screen
under the ground glass. With this
system, when your camera is
held horizontally and the image
is not in sharp focus, all vertical
lines seen through the viewfinder
will appear to be divided into
upper and lower portions, To
focus, simply adjust the focusing
ring until the upper and lower
portions are in perfect alignment.
As a general rule, your camera should be held more firmly in the
left hand, which does not release the shutter. If you hold your
camera with the right hand — the hand that releases the shutter —
this may cause camera movement. Often, blurred pictures are due to
camera movement.

After the final picture on the roll has been taken, the rapid-wind
lever will not turn, indicating that the film must be rewound. Lift up
the rewind crank. Depress the film rewind release button and turn
the rewind crank as indicated to rewind the film into its cassette.
Rewind until the tension on the crank lessens, indicating that the
leader end of the film has been released from the take-up spool.
Pull out the film rewind knob {the back will open automatically),
and remove the film cassette.

Depth of field is the range between the nearest and farthest
distances which are in focus at a given lens aperture.
If you want to know how great the depth of field is at a certain
aperture, focus on a subject and look through the viewfinder while
depressing the depth-of-field preview button @. Or, after focusing,
look at the depth-of-field guide on the lens. In the photograph
below, the distance scale is set at 5 meters . . . the lens is focused on
a subject 5 meters away. The calibrations on each side of the
distance index correspond to the diaphragm setting and indicate the
range of in-fôcus distance for different lens apertures. For example,
if a lens opening of f/4 is to be used, the range on the distance
scale ring covered within the figure 4 on the depth-of-field guide
indicates the area in focus at that lens opening. Your will note from
the depth-of-field guide in the photograph that the range from
approximately 4.5 to 6.5m is in focus. Note that as the lens
apertures change, the effective depth of field also changes. For
depths of field at different apertures and distance, refer to the next
page.

MIRROR LOCK-UP
In normal picture-taking situations, when you trip
the shutter, the reflex mirror swings up out of
the way. It then automatically drops back down
into place. Inevitably, this causes a small amount
of vibration — and the longer the lens you use,
the more noticeable the vibration will be.
To avoid this vibration, it is possible to lock the
mirror up. (Note: Moving the mirror keeps light
from the viewfinder and exposure system, so
focusing and setting of the aperture must be done
before lock-up. Use manual exposure setting,
which, unlike AUTOMATIC, will not be affected
by mirror movement. Also, you should use a
tripod for this kind of shooting.)
Once every thing is set, simply push up the lock-
up lever @ . The mirror will now stay up even
after you trip the shutter. To release the mirror,
return the lock-up lever to its original position.
The reflex mirror can be locked up either before
or after you advance the film.
22e
e 23
The self-timer delays shutter release between 5 and
9 seconds, depending on how far counter-clockwise
you have turned the self-timer @ . (This can be done
on either "AUTOMATIC" or manual shutter speed
settings. However, when the camera is set on
“AUTOMATIC”, some stray light may enter
through the viewfinder. To prevent this, we
recommend using the inexpensive optional
accessory, Viewfinder Cap.)
To operate, turn the self-timer lever down until it
stops. Depress the shutter button and the self-
timer will start.
The K2 self-timer also has an interrupt function.
Even after the self-timer has started to run, you can
stop it by moving the self-timer lever back to its
normal position. The remaining time will tick away,
but the shutter will never be tripped. To re-start the
self-timer, push the lever down again, and again
depress the shutter button.
The K2 has FP and X terminals near the film
rewind knob, and a separate X contact on the
built-in hot shoe. The table on the next page
shows which flash contact, which shutter speed
and which flash bulb may be combined for
maximum lamp efficiency. Unless these
combinations are rigidly followed, there will be a
failure in flash synchronization. Note the “X
setting is exactly at the 125 mark on the speed
dial. This indicates the highest shutter speed at
which electronic flash units may be used.
Use the hot shoe flash contact when using a
shoe-mount electronic flash like the Pentax
Autorobo which also has a flash contact on the
shoe bracket. When using the hot shoe, there is no
need to plug the flash cord into the X terminal
on the body front.
The hot shoe flash contact turns to “hot”
{switched on} only when you insert a shoe-mount
electronic flash. It remains “cold”
(disconnected) even when using an electronic flash
with its cord plugged into the X terminal on the
body front. This eliminates the danger of electric
shocks.
240
There are basically two types of flash bulb
attachments on the market: clip-on types and
bracket types. Either can be used with your
camera. The clip-on types are attached to the
hot shoe and the bracket types are screwed
into the tripod screw hole.
Use one of these three bulb types: M, MF or
FP. The correct terminal and the correct
shutter speed to use for each of these three
types are outlined in the table below.
Before attaching the flash unit to the camera,
you must remove the protective plug
from the proper terminal.
When not using the terminals, keep the
plugs inserted.

INFRA-RED
If you intend to take infra-red photographs,
remember to use the infra-red index marked with
an orange line on the depth-of-field guide.
First, bring your subject into clear focus.
Then determine the lens-to-subject distance from
the distance scale on the lens. Then match your
lens-to-subject distance to the infrared index by
turning the distance scale accordingly. For instance,
if your subject is in focus at infinity, turn the
distance ring and move the infinity (00) mark to
the index.

Conventional screw-mount Takumar lenses (both
Super-Takumar and SMC Takumar) can be easily
mounted onto your camera by attaching them first
to a Mount Adaptor K. Use of the Mount Adaptor
K does not affect any aspect of normal lens
function except as regards the following two
points:
1.
Due to the difference in coupling systems, the
automatic diaphragm will not function.
2.
Full-aperture metering lenses will function as
stop-down metering lenses.
280
HOW TO USE MOUNT ADAPTOR K
1.
Screw the conventional Takumar lens into the
Mount Adaptor K.
2.
Attach the Adapter/lens unit to the camera body
by aligning the red dots @ and @, and
turning the lens clockwise until it locks with
a click. (This takes slightly less than a quarter
of a revolution.)
3.
To remove only the lens, leaving the Mount
Adapter K attached to the camera body, simply
unscrew the lens counter-clockwise. Other screw-
mount Takumar lenses can then be attached in
the normal way.
1.
To remove the Mount Adaptor K from the camera
body, first remove the screw-mount lens. Then
press, with your thumbnail or a pointed object
such as a ballpoint pen, against the spring pin ® .
2.
Turn the Mount Adaptor K counter-clockwise
until you feel it release, and take it out.
e 29
Since the mechanism for locking in the Mount
Adapter K is totally different from that which
locks in an SMC Pentax bayonet-mount lens, the
lens release lever © on the camera body plays
no part at all.
Open-aperture SMC Pentax lenses have a
diaphragm coupling lever Q on the back of the
lens which locks into the camera body to permit
open-aperture metering. The super telephotos do
not have a diaphragm coupler, so they must be
used with the stop-down metering system.
Use of the Auto-Extension Tube Set K permits
open-aperture metering. It can also be set to
stop down the diaphragm automatically. Use of
other K Series accessories — standard Extension
Tube Set K, Helicoid Extension Tube K, Auto-
Bellows K and Bellows Unit K — requires stop-
down metering. Whenever any one of these is used
between the camera body and an SMC Pentax
lens, the stop-down metering system must be
used.

The temperature range at which your camera
will continue to function properly stretches
from 50°C to —20° C. However, resistance to
cold could be hampered by oil which has
become dirty. Therefore, if the camera is to
operate at full efficiency in very cold
conditions, it must be overhauled and all
oil must be replaced.
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 damaging to the
mechanism. Furthermore, if the camera goes
from a warm temperature to a sub-freezing
one, and if tiny drops of moisture freeze,
further damage may be done by their
expansion.
e 31
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.
Extremely low temperature reduces the
efficiency of the battery. Therefore, the camera
should be protected against low temperature.
Put the batteries into the camera right before
shooting. For extremely low temperature, use
new batteries.
CAMERA MAINTENANC
1.
Always keep the viewfinder eyepiece, fens and
filters as clean as possible. To remove loose dust
and dirt, first use the blower and then the brush of
a lens brush. Do not try to wipe off granular dirt
or dust — it's an excellent way of scratching the
glass.
Smudages, such as fingerprints, should be carefully
wiped away with either a lens tissue or a clean, soft
cloth. Clean, plain cotton handkerchiefs that have
already been washed a few times are particularly
good for this. Breathing on the lens before wiping is
effective; but be sure to wipe away all moisture
completely. Commercial lens cleaners are also
effective.
2.
Never touch the mirror or the shutter leaves with
your hands. (The natural acids on your skin are
very damaging.— Minor dirt or spots on the mirrar
will not affect the clarity of your pictures.
3.
Take care not to drop the camera or knock it
against anything solid. Accidents or rough
handling can easily damage the internal
mechanism, even though externally nothing
seems to have been hurt,
320
4.
Your camera is not waterproof. There are several
places where water can get inside and do a great
deal of damage. Take care to protect both body
and lens from rain or splashing water. If your
camera should get wet, dry it off immediately
with a clean, soft cloth.
Once a camera has become completely soaked,
there is often nothing that can be done to make it
right again. However, in such a case, take your
camera as soon as possible to an authorized Asahi
Pentax Service Center.
5. .
Where to keep your camera while you are not
using it is an important point. The beest storage
place is cool, dry, clean and well-ventilated.
Because of the possible build-up of humidity, it is
risky to store your camera in a cabinet or closet.
It's also a good idea to keep your camera in its
bag or case while you are not using it.
6.
When mounting your camera on a tripod, be sure
the tripod screw is no longer than 5.5mm. This is
the depth of the tripod screw hole on your
camera. If you use a longer screw, you will
probably puncture the bottom of the hole, after
which the camera will not function properly.

All Asahi Pentax cameras purchased through
authorized bona fide photographic distribution
channels are guaranteed against defects of
material or workmanship 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 equimpent has not been abused, altered, or
operated contrary to instruction. 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 alternations except
those made with its written consent and shall not
be liable for damages from delay or loss of use or
from other indirect or consequential damages of
any kind, whether caused by defective material or
workmanship or otherwise: and it is expressly
agreed that the liability of the manufacturer or its
representatives under all guarantees or warranties,
whether expressed or implied, is strictly limited to
the replacement of parts as hereinbefore provided.
PROCEDURE DURING 12-MONTH
WARRANTY PERIOD
Any Asahi Pentax which proves defective during
the 12-month warranty period should be retuned to
the dealer from whom you purchased the
equipment 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 equipment
can be returned to you owing to the complicated
customs procedures required in Japan in importing
and re-exporting photographic equipment. 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 Asahi Pentax was purchased outside of the
country where you wish to have serviced during
the warranty period, regular handling and servicing
fees may be charged by the manufacturer's
representatives in that country. Notwithstanding
this, your Asahi 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
34e
accredited repair shops, unless you are sending it This warranty policy does not apply to Asahi
directly to the manufacturer. Always obtain a Pentax cameras purchased in the U.S.A. For these
