      ASAHIPENTAX
    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 dependable exposures 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.

    Through the viewfinder, you wili obsbrvethe
    movement of the meter's needleon the right
     side of the ground glass. Be sure to turn off
     the meter's switch when not actually taking
    readings.


     5. ROTATE DIAPHRAGM RING
   The needlemovesup and down with the turn
    .  of the d,iaphragmring. When the needlerests
     at the centre, you will get correct exposure.
       If the needle does not come to the centre no
    matter how far you turn the diaphragm ring,
    change the shutter speed. When the needleis
     off centre and closeto the (t  ) mark, you will
    get over-exposure:change the shutter speed
     to a faster setting.  If the needleis closer to
    the (-)  mark, you will get under-exposure:
   change the shutter speedto a slower setting.

    Hold your camera,firmly and trip the shut-
     ter. When the shutter is released,the meter
    switch will automatically turn off, and the
   needle will remain fixed off and underneath

     full aperture and the 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
     is not necessaryto repeat instructions 4 and 5.)

           your subject image is clearly in focus.
                   It is not always necessary for 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-
          serve the depth of field.  It  is easi-
             €r, however, to focus with the dia-
         phragm  fully open as your subject
         image is much brighter.
                        "MAN"          When the letters        appears

              is in automatic position.
          Microprism
          Asahi Pentax camerashave a Fresnel
           lens with a microprism centre under-
          neath the ground glass. As you look
          through the finder, you will see that
           the Fresnel lens consists of 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
           subject is 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 image up into many small dots,
        much  like  engraver's screen. You
         can focus your subject on any por-
            tion of the ground glass.

Rangeof light measurement
    The exposure meter of the Spotmatic measuresthe brightness of the ground
     glass. Therefore, the meter should be turned on alter you have focused
     your subject on the ground glass. The follorring table shows the range of
     the meter's light measurement, and should not be interpreted as the cam-
     era's total range of f/stop-shutter speed combinations. As you will  note

     from 1 sec. to 1/1000sec. 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 apertures of the lens being used. For example, u,ith the 50mm f./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 1/1000sec. that wili bring the meter needle to midpoint.

Flashsynchronization


   The Spotmatic  II has FP and X terminals  at the front of the camera body,
   and a separate FP/X  contact on the built-in hot shoe. The table below shows
   which  flash contact, which shutter speed and which  flash bulb may be com-
   bined for maximum lamp efficiency.  Unless these combinations are rigidly                                                                             "X"   followed, there  will  be a failure  in flash synchronization.  Note the
   setting  is exactly at the 60 marked on the speed dial.  This  indicates the
   highest shutter speed at which electronic flash units ma1" be used.
   Use the hot shoe flash contact only when using the Super-Lite  II  or any
   other  electronic  flash or flash gun  that has a flash contact on the shoe
   bracket. To select FP or X, just turn the FP/X  switch rim so that eiether
   one of the marks appears in the window.

How to take care of your camera


     1. STORAGE

      a)  The  instrument,  when  not  in use, should be protected  from  damp-
     ness and dust.  Preferably,   it should be kept  in its case and, as an addi-
       tional  precaution,  inserted  into a polyethylene  bag.

      b)  Care should be taken  to see that  the camera  is not  kept  in abnor-
      mally  high  or low temperatures  - normal  room temperature   is best.

       c)  Take  the precaution  of removing  any batteries  since, no matter  how
       well  made  these may  be, there  is always  a  risk  of  deterioration  and
      corroslon.

     2. EXERCISE

       All mechanical instruments need to be exercised regularly to keep them
       in good condition. Cameras are no exception to this rule.   If you put
     your car in storage for the winter, the first thing a prudent owner does
       in the spring is to have it serviced before putting  it back on the road.
     There is not quite the same parallel between a motor car and a camera,
      nevertheless,you should store your camera where you can get at it easily
     and put  it through its normal operations at least once per mOnth.  i.e.

      a)  Set the shutter release and fire.

      b)  Turn  to a slow shutter speed and again .set the  shutter  release and
        fire.  Also operate delayed action device (self-timer).

       c)  Examine the exposure meter  for  correct  operation.

      d)  Check film transport.

      e)  Check the range finder or pentaprism viewfinder.

     These actions will  keep the mechanism in good order, retaining the
      natural qualities of the lubricant - thus ensuring the camera is ready for
      instant use when required.

 3. RUNNINGTEST BEFOREUSE
 Before embarking on a holiday where your camera will be your constant
 companion or, in fact, any other reason for the camera being required
 on an important assignment, make a few  trial exposures.  It  is advis-
 able to test the camera at least four weeks prior to your departure to
 give time  for a test film  to be exposed and processed. NIany spoiled
 holiday records would have been avoided if  this precaution had been
 taken.

 4. DUSTYCONDITIONS
When your camera is used on the beach, or other conditions where dust
or sand can easily infiltrate the mechanism, take the precaution of put-
ting the instrument with  its case into a polyethylene bag or other con-
tainer so that flying dust or sand are prevented from entering the cam-
era.  This applies particularly, of course, if  it  is laid down on a sandy
beach. Furthermore, avoid leaving the camera in such a position that
direct sunlight is allowed to fall upon  it for a long length of time.

5. LOOSEPIECESOF FILM
This nuisance is often the cause of trouble with a camera. Small chips
of fitm can easily damage the mechanism. Therefore, check your cam-
era every time  it  is loaded. Always make sure  it  is free from small
pieces of film.

6. TREATINGYOUR CAMERATENDERLY
Your camera is a fine, precision instrument.   It has been produced with
great care and attention to detail. Do not allow  it to be swung by its
shoulder strap, thrown  into  the back of a  car, or  in any other way
treated as if  it were as robust as a battleship.  If you protect the cam-
era against possible damage due to a knock, you will be amply repaid
by years of excellent and trouble-free service.
