   it of the take-up spool @.  Slowly turn the
film winding knob Q clockwise and make
sure  that  both  sprockets @ have  properly
caught the  perforations  of  the  film.  Again
yake sire  that  the  film  is being properly
transported on to the take-up spool, and then

Before focusing through the focusing  l-1           Bnder glass, be sure that the shutter
           has been cocked  first.".d#              Remove the lens protector cap, and erect the 4 1

            the image on the focusing glass while turning I I
            the distance scale ring @.  When the image on
            the focusing glass becomes clearest, an accurate
             focusing will be obtained, and the same image
              will be produced on the film plane as the shut-
               ter is released.
             To ensure accuracy in focusing, a magnifier
     @ is attached  to  the  rear  finder hood.  The
            magnifier may  be  set  parallel to the focusing
              glass by holding the nipple on top of the mag-
                nifier.  When observing through the magnifier, l
           keep your eye close to the magnifier.

                           At distance 15 it. with 50 mm lens
          and at the following diaphragm setting, the range of
            distance shown below is in the same depth-of-field.11



           On each of our TAKUMAR lenses, different depth-
              of-field guide numbers are shown according to its focal
             length.
               Hence, when taking two or more objects of different
             distance,  it  is necessary to adjust the diaphragm piro-
             perly in order to bring these objects simultaneously in
            focus as illustrated by the photograph.
              With ASAWFLEX, you can clearly ske what is in
            the depth-of-field on the focusing glass,  You will also
            see the extent  of  blurs that  will be produced on the

PRE-SET DIAPHRAGM

               It is sometimes hard in single lens reflex camera
         to obtain  correct focusing when the diaphragm is set
        prior to focusing because of the darkness of the focusing
        finder glass.   Hence, focusing is usually 'secured with
        the diaphragm full open, and adjusting it after focusing.
         To eliminate  this inconvenience  of keeping your
        eyes  off  the  focusing  glass  to  set  the  diaphragm,
     ASAHIFLEX  is equipped  with  a  pre-set diaphragm

              letters B and T on the shutter speed  dialr
            function as follows :
                  3J (Bulb)-The   shutter is open as long as "f'                         the shutter button  is pressed.

                        used for long exposure timing.              shutter button is pressed ; however, the
        MODEL IIB                                   Model IIB has na slow speed shutter    .
             1   Turn the shutter cocking knob clock-             with T setting. When a long timing
                  wise until  it stops.                                        is desired with Model IIB, unscrew the
                  2.   Lift the shutter speed dial, turn to the              shutter ring and fix a shutter release
                    right or the  lef;  and  set the desired             cable with locking attachment.  Thus'I           speed number to the index.                       long exposure timing may be  easily

To obtain satisfactory synchronization with electronic
flash,  it is preferable to set the shutter speed slower than
1/25 of a second.     -
