tilmWinding

  The   f ilm advance lever winds the   f ilm, cocks the  shutter,
  and prepares the  mirror  for  the next shutter release all  in
  one motlon.
     I  Turn  the  film advance lwer  until   it  stops.  The  film
     I   will  be advanced one    f rame and  the  shutter  cocked.
  The  frame counter  is simultaneously advanced to  the next
  number.
    When the shutter release button  is depressed, the mirror    lf
  4   ttips up,  the diaphragm simultaneously closes down  to
   the proper f/stop  (in case of manual control, to  the pre-set
   f/stop) and the shutter operates. After the shutter is operated,
   the advance lever can be wound for the next frame.
     I  Winding may be done by moving the  lever with several
   short strokes.
     I   After  loading the film, make another wind, because only
   with the first wind  it may not be completed.
     f  The shutter witl not function when depressingthe shutter
   release button  unless the  winding  is completed.    In such
   a case, check the winding once more.
  Frame Counter
  Each winding will advance the number of the frame counter,
   indicating the number  of  pictures taken.  When the back
   cover is opened, the indicator automatically returns to starting
   position "S".

 at the proper position.
 Lift  the film speed set ring around the shutter speed d i a l ,
 and set the proper ASA  f ilm speed number.

PhotographywithilectricEye

For taking pictures with Electric Eye, set the aperture control
ring at "EE".
I  The Electric Eye  is fully coupled to the ASA film speed,
the  shutter speed and  the  aperture.  The diaphragm  will
close down  to  the proper   f /stop  and  exact exposure  is
determ ined by simply depressingthe shutter releasebutton.


                                                                    72..J^102

ShutterSpeedAdjustment

   Adjust the shutter speed by  turning the shutter speed dial
    to the desired index number.  The index on the dial shows
   the denominators of 1/500 sec., 1/250 sec., etc'
       t  Be sure to  set the index  at a position where the click-
   stop catches.
       I   "8"   indicates bulb exposure, and  is used when making
    indefinite timed  exposures.  When  the  shutter speed dial
     is set at "B",  the shutter remains open as long as the shutter
    releasebutton  is depressed.
       I  Time  exposure, making an exposure over an extended
    time,  is possible by  using the  lockable cable release and
    setting the  shutter speed dial  at  "8".
       I  The  "60"  index  is used for  synchronizing an electronic
    flash unit such as Canolite D.  Although the shutter speed
    at "60"   is 1/60 sec., it  is equivalent to a very short exposure
   time during the flash of the electronicflash unit.

  The  center of  the viewfinder  (circular section) is a micro-
   prism screen rangefinder made up  of  microscopic prisms for
   fast and precise focusing.
  While  looking through  the  viewf inder, rotate  the  focusing
   ring.   lt  is in focus when the image in the rangefinder becomes

CheckingtheExposureIndicator
 Turn  the aperture control  ring to  "EE,,.   point the camera
 at the subject and check the position of the exposure indicator
 inside the viewfinder.
   You may depress the shutter release button   if the indicator 1
  I   is pointing inside the proper exposure range.
 ,)   lf  the  indicator is pointing to  the over-exposure warning
 L  mark,  either  the  shutter speed dial  should be revolved
to  the  higher index side until  the  indicator moves to  the
proper exposure range, or a neutral density (ND)  filter must
be attached to  restrict the incoming  light.
      lf  the indicator is pointing to the under-exposurewarning?
 t  mark,  either  the  shutter  speed dial  should be revolved
until  the  indicator moves to  the  proper exposure range, or
light source must be increased.
 I  Upper  splitted  part  of  the  under-exposure warning mark
applies only  to  the F3.5 lenses, i.e., the 35mm wide-angle,
95mm and 125mm telephoto lenses.
 t  The  Electric Eye mechanism functions  only when  the
aperture control  ring  is set  at  "EE',.

Coupling Rangeof the Electric EYe
             The  Electric Eye couples to  the  following  range of  f/stops
              and shutter speeds with  respective film  speeds. When using
I G              the Somm  standard lens and ASA  100  film,  for example,t   l
E                the  Electric Eye  couples fully  within  the  range of    f 11.8
55                at 1 18 sec. and fl16 at 1 /5O0 sec.
Iu                            I  The  Electric Eye does not function  at "8"  of the shutter
t8             speed dial becaus        is used for indefinite timed exposures.
                               I  When  the  Electric Eye  is  outside the  coupling range,
                the exposure indicator  will  point  to the over/under exposure
              warning mark, and will  indicate that proper exposure cannot
              be obtained.

Setting Distance Scale of 35mm, 95mm and
 125mm Lenses
  When using the 35mm wide-angle,95mm or 125mm telephoto
   lens, be sure to set its distance scale on the front component
  properly.

     I  When  using  the 95mm   or  125mm   lens, focus  precisely
  since the depth-of-f ield is shallow.
     I  Be  sure  not   to  tu rn  the  adjusted  distance  scale on  the

  Distance Scale
  The  distance scale indicates the distance between  the focused
  subject and  the  film  plane.  The  scale  is used  for  checking
   the  depth-of-f ield,  for    f lash and  inf rared photograph ies.
     I  The  correct   position   of  the  scale  is  in  the  center  of
  each value.   For  example,  the correct  position  of  a two-digit
  value  is the center  of  the two  figures.

Depth-of-field 2.3m-4.3m  (8'- 14')    Depth-of-Field Scale
Focusedat 3m (10')                                 The depth-of-field scale wh ich  is applicable when using the
                            50mm  standard lens, indicates the range of  subfects wh ich
                                                 will  be  in focus sharply on the film.   This range will vary
                                       with  the  following  factors:    The  depth-of-field will  be
                                   deeper the  smaller the  aperture opening, the  further  the
                                       distance of  the  subject, and/or  the  shorter  the  lens focal
                                         length.  The depth-of-field will  be shallower the  larger the
                                       aperture  opening,  the  nearer the  distance of  the  subiect,
                                      and/or  the  longer the  lens focal length.  For example,  if
                                         the Somm  standard  lens  is used and  the  subiect has been
                                    focused at a distance of 3m  (10'), with an  f 18 aperture value
                                     read off  from  both  indexes on  either side of  the  indicator
                                    (orange line), the depth-of-field is from approximately 2.3m
                                                 (8') to 4.3m  114'1.   lf  the aperture is closed down to t116,
                                        the  picture  will become sharp between 1.9m  (6')  to  7.6m
                                          125') from  the camera.  This range will vary with  the f/stop
                                          selected.
