BEFORE I.OADING WIT}I FILM FOR PICTURE.TAKING
  Read these instructions carefully so that you know the special features offered by the
single-lens reflex construction of your camera.
  PICTURES EXACTTY AS SEEN IN THE VIEWFINDER.
  By use of a special pentaprism in conjunction with the picture-taking lens, the image
seen in the viewfinder is identical with the negative reproduction of the subject on the film.
Although there is a brief black-out of the viewfinder image for a fraction of a second
during shutter action, you can always see exactly what you are taking
  PRECISE FOCUSING
  The light rays reflected by your subject pass through the main lens, and are deflected
upward by the quick-return mirror to form an image on the viewing-focusing screen. This
image is seen in correct orientation and size through the viewfinder eyepiece and the pentaprism
which reflects the rays three times. When the focusing ring (6) is turned the image of the
subject, formed on the viewing-focusing screen, can be adjusted to maximum sharpness.
With the subject thus brought into correct focus, precisely as it  will register on the film,
the shutter button (2) can be pressed for actual shooting. Because the focusing and viewing

www.butkus.us
are done through the same iens as for  picture-taking, there is no sighting error
(parallax), while you are enabled to ascertain visually the extent of blurring of the areas in
front of and behind the main subject which is in sharp focus. With the focus set at
infinity (oo), the viewfinder image is x0.8 magnification.
  OUICK.REIURN MIRROR,
 When the shutter button (2) is pressed to release the shutter mechanism, the reflex
mirror flicks up to return to its original position the instant the action of the shutter is
completed. Consequently, the subject is always clearly visible in the viewfinder except
during the movement of the shutter.
  FUIL-APER URE VIEWING AND FOCUSING
  This camera is  provided with a fully automatic aperture mechanism which closes
down to pre-set aperture size only during shutter action. This means that maximum
aperture size is always available for viewing and for utmost precision in focusing.
  APERIURE IEVER
  For checking the effects of pre-selected aperture size, there is provided a manual aperture
lever (7) which permits viewing at any f/ stop desired. Releasing this lever immediately
gives full aperture for viewing or focusing.

COCKING LEVER
  This lever (l) sinrulianeously cocks the shutter and advances the film one frame in one
strolie. It rernains loclied until the shutter button (2) is operated and the shutter mechanism
is released. This arrangement positively prevents double exposures.
  SHUIIERSPEED DIAI
  This dial (4) can be sct at any time, either before or after cocl<ing. Click stops are
provicled at each setting. When position " B " (bulb-manual shutterspeed control) is used,
tlic siruttcr remains open fcr as long as the shutter button (2) is liept depressed, and during
this 1i15s the viervfinder rvill remain blacked out.

                                    FILM TOADING
                        This camera will  take any 3S-millimeter film
                               preloaded in safety cartridge. Monochron:e or color in
                                  20- or 36-exposure lengths may be used. When loading or
                              unloading film, always avoid direct lighting. Work in
                               the shade, using your own body as a shield if no other
                                   protection is available.

  4. Cover the lens with the lens cap. Operate cocking
lever (1) and the shutter button, making blanl< shots, until

the film counter (8) indicates numeral 1. The first frame of your film is now in position
for exposure.
  5. Finally, turn the filmspeed dial (L7), and set the ASA rating of the film you have
loaded in your camera against the triangular index mark. You are now ready for picture-
taking.

                  EXPOSURE IIETER READING
                                     The built-in exposure meter
                                                         of your camera accurately indicates
                                            the  brightness (light  value)
                                                of  your  subject. The  red
                                                    needle (19) will stop at one of the
                                                            striped guide lines. The aperture

I      exposure of your film for the brightness of your subject-matter.
        1. Make sure that the filmspeed (ASA) dial (17) is set at the ASA rating of the film
      you have in use.
        2. Turn the exposure meter dial (18) so that the shutterspeed setting you wish to use
       appears in the dial window " TIME "I
        3. Point your camera toward your subject, then by noting the position of the exposure
l      meter needle (19) obtain the proper aperture value for correct exposure. Adjust the aperture
I      ring (5) to set at the indicated value.
        cAufloNs
         When using the exposure meter, be sure that the photocell window (16) is notI      1)
         obstructed in any way.
       2) When, with shutterspeed at 15 (1/15 second), the exposure meter needle (19) is not
          deflected sufficiently to indicate aperture setting 2.8 (f 12.8) or beyond, your subject is not
         bright enough for good exposLrre. Either the lighting must be improved or film of higher
        speed rating will have to be used.
       3) When, with shutterspeed at 250 (71250 second), the exposure meter needle (19) moves
        beyond 22 (t/22), the subject is tqo bright, and overexposure will result. Use a filter to

reduce the intensity of the light entering the lens. Froceed with caution however since
       extraneous light (from the sun or the sky) may be causing the exposure meter to indicate
        lighr value higher than that actually pertains to your subject.
      4) When using a filter, change the filmspeed (ASA) setting of dial (17) according to the
       exposure factor of the filter. For instance, if you are using film of ASA 100 in conjunc-
       tion with a filter with a factor of X3, you are in effect reducing your filmspeed to one-
        third of its rating, namely ASA 33. In this case set the filmspeed dial (I7) at a position
       between 50 and 25.

             HOTDING YOUR GAMERA FOR PICTURE.TAKING
       Supporting the camera on the palm of your left hand, the thumb and forefinger should
      rest lightly on. the focusing ring (6), ready to make focusing adjustments. The right hanc
     should lightly grip the right side of the camera, with the index finger free to rest lightly
    on the shutter button (2). The thumb may be lightly hooked on the end of the cocking
     lever (1).
       Raise the camera to eye level, and sight through the eyepiece (3). You will then have a
      stable grip and stance. The left hand is used mainly for steady support, while the right

                          FOCUSING
  Focusing is done by turning the focusing ring (6) while sighting your subject through
the eyepiece (3). While  it is easier to sight and focus at full aperture, you may wish to
know horv much focusing tolerance (depth of field) you have at the aperture setting you
have selected. Actual picture-taking conditions can be immediately checked merely by
pressing the aperture lever (7) to close down the iris diaphragm to the pre-set aperture size.
 When the subject-matter is too dark for accurate focusing by sight through the viewfinder,
set measured or judged distance on the distance scale (9), and note available depth of field
(focusing tolerance) by means of the color-coded depth of field scale (10). The colorscor'
respond to those of the aperture scale on the aperture ring (5). For precise depth of field
computations, consult the depth of field table.
  NOTE
  Color-coding of the aperture scale (5), depth of field scale (10) and the exposure meter
  dial (18) is as follows:
   red-orange           ............2.8  (fl   )          orange'yellow"""""""""""""""4
    yellow-green........................5.6         green                      """"'8

UNTOADING FILM
  When yffu have taken the number (either 20 or 36) of pictures available on your film,
stop trying to squeeze in any more. Rewind your exposed film into its safety cartridge
before opening your camera.
  1. Press sprocket release button (20), making sure it remains depressed. Erect rewind
crank (12), and turn clockwise in the direction indicated.
  2. When the end of the film separates from the take-up spool (15), you will sense this
by feel. Do not wind film fully into the safety cartridge. Open backlid, pull out rewind
crank (12) and remove safety cartridge. The depressed sprocket release button (20) will
return to normal position automatically upon operation of the cocking lever (1).
  GAWIONS
  1)  If at the end of your film (sometimes before the film counter (8) indicates the full
  number of frames available) the cocking lever (1) lams part way through its stroke, do
  not force. Press the sprocket release button (20), and complete cocking action. Rewind
  film into safety cartridge.
  2)  If jammed cocking lever is forced, the film may be stripped or the end may come

www.butkus.us

   loose out of the safety cartridge making it impossible to rewind. If this happens, and
  you wish to save your film, open camera only in complete darkness.
                 SYNCHROFLASH PHOTOGRAPI{Y
  This camera is provided vrith a synchronizing mechanism for setting off photoflash
 simultaneously with the action of the shutter. Since there is no provision made for
 time lag, accurate synchronizatiorr  is possible with electronic flash (strobo) at all shutterspeeds,
and with class M and class F flashbulbs up to speeds of 7130 and 1/60 second respectively.
  On the front of the camera, there is provided a synchroflash socket (2I) of. the JIS-B
 type (German type).
  To mount flashgun on your camera, screw adaptor into the accessory mount socket (23).
