ASAHI
PENTAX
SPOTMATIC II
Your Asahi Pentax Spotmatic II is the finest photographic instru-
ment on the market. The "Super-Multi-Coating" on the Takunrar lens,
developed by Pentax and available only on Spotmatic II Takumars,
reduces flare and boosts contrast to a degree far beyond rvhat was
previously possible in optical technology. It is a tougher coating than
is available on any competitive lenses and results in pictures rvith more
detail and richer colours than is possible with any other system at
any price.
The Spotmatic II itself is an outgrowth and refinement of the orig-
inal Spotmatic which introduced through-the-lens metering to the world
of photography. Its stopped-down metering system is the most accurate
method for perfect exposure determination. It also automatically gives
you a depth-of-field preview. It is an averaging system for the easiest
and most dependableexposures in typical picture-taking situations. This
metering system has been refined and improved each year in the Spot-
matic to a degree of accuracy unmatched in the industry.
The original Spotmatic was the most compact 35mm SLR made.
The Spotmatic II retains that same traditional compactness and classic
feel. It also is designed for use with the accessories from the Pentax
system, including all of the superb Takumar lens ranging frorri the
ultra-wide-angle 17mm Takumar up to the super-telephoto l000mm
Takumar. The Pentax system can grow with you as your interests
develop in any direction.
We are very proud of the Pentax Spotmatic
II. We are sure you
will be,too.

1.,SET
FILM SPEED
Lift the outer ring of theshutter speed
dial,
turn it around and set the same number as
the ASA number of the loadedfilm to the
small red index which appears
alongside
the
figure 1. Then cock the rapid wind lever.
2. SET SHUTTERSPEED
Turn theshutterspeeddial
andsetthe
speed
you wish touseto the index. When outdoors,
set the speed
at l/125 sec. or faster, depend-
ing uponthe lighting.Whenindoors,set
it at
L/30, or in its neighbourhood. Change the
shutter speed
later, when necessary.
(Refer
to 5 on the next page.)
3. COMPOSE
AND FOCUS
While viewing through
theviewfinder,
turn
thedistance
scalering with your thumband
index finger until you getthe sharpest
image
of your subjectat the microprismcentre
of
the finder.

4.TURN ON LIGHT METERSWITCH
Push
up thesrvitchbutton
with vortr
thurnb.
Throughtheviewfinder,
youwili obsbrve
the
movement
of themeter's
needle
on theright
side
of the ground glass. Be sureto turn off
themeter's
switchwhennot actuallytaking
readings.
5. ROTATE DIAPHRAGM RING
The needle
moves
up
and
downwith theturn
. of thed,iaphragm
ring. Whenthe needlerests
at the centre, you will get correct exposure.
If theneedle
does
not come
to thecentreno
matter how far you turn the diaphragmring,
change
theshutter speed.
When theneedle
is
off centre
andclose
tothe(t ) mark,youwill
get over-exposure:
change
the shutter speed
to a faster setting. If the needle
iscloser
to
the (-) mark, you will get under-exposure:
change
the shutter speed
to a slowersetting.
6. RELEASE
SHUTTER
Hold your camera,firmly and trip the
shut-
ter. Whentheshutterisreleased,
themeter
switch will automatically
turn off, and the
needle
will remain fixed
off and underneath
thecentre. The diaphragm
will reopen
toits
full aperture
andthe overali image will look
brighter. Cock the rapid wind leyer for the
next picture. (When taking a series
of pic_
tures under the same iighting conditions,
it
isnotnecessary
torepeat
instructions
4and
5.)

Howto holdyour camera
In horizontal position A. Hold
the camera firmly with your
left hand, and draw your arm
close to your body.
In vertical position B. Hold
your camera tightly to your fore-
head with your left hand, and
draw your right arm close to
your body.
In vertical position C. Hold
your camera tightly to your fore-
head with your left hand, raise
your right arm and draw your
left arm to your body.
Asa
general
rule,
yourcamera
should
beheldmorefirmly by the left hand
which does
not releasethe shutter.
If you hold your camera with the
right hand
-- thehand
which releases
the shutter- it may cause camera
movement. Very often, pictures
which are not sharparedueto move-
ment of the camera. When youfocus
with the camera held horizontally
(Position A), hold the lens barrel as
illustrated. Cradle the camera with
your left hand thumb and little fin-
ger. Turn the diitance scale ring
with your thumb and index finger.
When holding the cameravertically,
some
people release
the shutter with
the thumb (PositionB), while others
releaseit with the index finger (Posi-
tion C). Position C ismore desirable
for fast focusing and shooting. With
the Asahi Pentax, whether held ver-
tically or horizontally, you see your
subject image through the taking
lens, enabling you to compose,
focus
and shoot with a minimum of time
and effort.

Film type reminderdial
Usethe film
type dial to
show what
type of film
is in your
camera.
When you
have pulled out the rewind knob to
open the back when loading the
film, turn the dial selector so that
the type of film appearsin the win-
dow. To check whether the camera
isloaded,
turn the film rewind knob
clockwise. If it turns freely. the
camera is not loaded.
Film
loading
Avoid direct sunlight when loadingyour
film.
l. Open the back by pulling out the
rewind knob until back cover snaps
open.
2. Place the film cassette
into the cas-
sette chamber,
andpushbackthe re-
wind knob. Draw outthefilm leader
and insert it into slotof the take-uo
spool.
3. Advancethe film by alternately turn-
ing the rapid wind lever and releas-
ing the shutter until both sprockets
have properly engaged
the film per-
forations. Close
the backby pressing
it firmly.
4. If the film is properly loaded,
the re-
wind knob will turn counter-clock-
wise when you advancethe film by
turning the rapid wind lever.
Setting ASA film speed
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. Lift theout-
er ring of the shutter speed
dial and
rotate it until the ASA number of
your film is opposite
the red index
mark.
Be sure to set your film speedon
the shutter speed dial becausethe
dial is connected to the exposure
meter system.

ture is ready to be taken.
2 After the final picture on the
roll (20 or36exposures)
hasbeen
taken, the rapid wind lever will
notturn all the way as
youstroke
it. This indicates that thefinal
picture has been taken on your
film, and that the film must be
rewound. DON'T open theback
of the camera, or all exposed
frames will be ruined.
3 Unfold the film rewind crank.
Depressthe film rewind release
button. Turn the rewind crank
to rewind the film into the film
cassette.The film rewind crank
permits rewinding at a smooth,
evenrate. (Under someatmos-
pheric conditions,erratic or too
rapid rewinding will cause
static
electricity marks,on the film.)
You will feelthe tensionon the
rewind crank lessen as
theleader
endofthe film slipsoff the take-
up spool.
Stop rewinding when you feel
this happen. AVOID DIREC'f

It is not always necess
aryfor you to
view and focus with the diaphragm
fully open. In bright sunlight, you
can easily focus with diaphragm
closed to f/5.6 or f/8 and still ob-
servethe depth of field. It is easi-
€r, however, to focus with the dia-
phragm fully open as your subject
image is much brighter.
When the letters "MAN" appears
besidethelever,
the lens
isin manual
position; when "AUTO" appears,
it
is in automatic position.
Microprism
AsahiPentax
cameras
have
aFresnel
lens
with amicroprism centreunder-
neaththe groundglass. As you look
through the finder, you will see
that
the Fresnel lens consistsof many
concentric rings which provide the
brightest possible image on the
ground glass.
The microprism is the centre por-
tion of this diagram. When your
subjectis in focus,the image in the
microprism will be sharp and per-
fectly clear. If your subject is not
in focus,the microprism will break
the imageup into many small dots,
much like engraver's screen. You
can focus your subject on any por-
tion of the ground glass.

before
or after making your exposure,
or, if
you are making pictures in bright

as long as you depress the shutter
button. As you releaseyour finger
from the shutter button,the shutter
closes. When a long exposure is
desired while using the B setting,
attach a shutter release
cablewith a
locking device
to the shutter button.
This will permit a "Time" exposure.

ism, trip the shutter release
be-
fore putting the camera out of
use for any extended period.
If you want to know how great the
depth of field is at a certain aper-
ture, look at the depth-of-field guide.

Range
of lightmeasurement
The exposure meter of the Spotmatic measures
the brightness
of the ground
glass. Therefore, the meter should be turned on alter you have focused
your subjecton the ground glass. The follorring table shows the range of
the meter's light measurement, and should not be interpreted asthe cam-
era's total range of f/stop-shutter speedcombinations. As you will note
from the table below, with an ASA100 film, -v-ou
may use
any shutter speed
from 1sec.to 1/1000 sec.in combination rvith any aperture that will bring
the meter needle to the midpoint in the viervfinder. The total range of
the aperture settings is, of course,determined by the minimum and max-
imum aperturesof the lens being used. For example,u,ith the 50mmf./I.4
lens and ASA100 film, an aperture from f ll.4 (the maximum aperture of
this lens) to f
/16 (the minimum aperture) may be used with any shutter
speedfrom 1
sec.to 1/1000 sec.that wili bring the meter needleto midpoint.
