   VIEW_FINDING AND FOCUSING
1. Push upward the direct view-finding frame as shown in the
    picture. When taking 6 x 6 mm pictures, scenes seen on the
    entire froSted glass screen are the boundaries of the picture to
   be taken. When taking 6x4.5 mm pictures, the boundaries of the
    the picture should be between the two heavy red lines on the
    frosted glass screen.
2. After the distance is set, the view-finding cover may be pushed
   down when finding views directly through the view-finder frame.
3. At view-finding, the eye must draw close to the small aperture
    of the view-finder frame, scenes seen directly will be the range
    of the picture.
Note:- The direct view-finder frame may only be used when
    taking 6xO mm pictures.

5.  By turning the focusing knob 15, when the image of the object
    to be photographed is very sharp, the correct distance is thus set.

    In the course of focusing, when it is necessary to see clearly the
   image by means of the magnifying glass, the magnifying glass
     will arrrtomatically jump up when its locking catch is plucked.
   When not in use, the frame of the magnifying glass can be pushed
   down to lock it in its original place.

     DEPTH OF FIELD
The range of the depth of field may be read from the depth-
of-field scale engraved on the focusing knob.
As shown in the picture, when the distance is 5 meters and the
aperture selected is F 1 1, the depth of field will be approximately
from 3.4 to 8.9 meters, and scenes photographed within this
range will be clear.
With a fixed object: the smaller the aperture, the greater the
depth of field will be.
with an unchanged aperture: the farther the distance; the greater
the depth of field will be.
