Focusing and Focusing Knob Fixing
Distance Scale

Focusing
When the shutter is cocked, the mirror is
cocked simultaneously, and an image is
visible on the ground glass of the focusing
screen. By turning either the left or right
focusing knob, adjust the focus and com-
pose the picture.

Focusing knob fixing
After adjusting the focus, turn the focusing
knob fixing lever (18) forward and appropri-
ately clamp it, whereby the focusing mech-
anism is secured.
Deviation in focusing can be prevented
in this manner, when continuously taking
pictures, taking snapshots with wide-angle
lenses, close-up photographs, and using
telephoto lenses.
Distance from the film plane to the subject
can be determined by the distance scale
(5).
Curves on the distance scale are repre-
sented in a different color for each lens.
The figure on the distance graduation (4)
which meets the curve for the lens used
after focusing reveals the distance to the
subject.
For example, if the distance graduation and
the curve are as shown in the photo after
focusing with the 127mm lens, you can con-
firm that distance to the subject is 5ft. (1.5m)
by reading the graduation aligned with the
orange curve.
