Focusing and Bepth of Field
The focusing ring is closest to the camera body. It
has a knurled rubber grip and engraved distance
scales in feet (orange) and metres (white). Focus
the lens by rotating the focusing ring until you
obtain a sharp image of the subject in the
viewfinder.
The distance between the subject and the film
plane is read off the focusing ring's distance scale
opposite the central lens index.
Objects closer or further away than the selected
distance will be sharp, within certain limits. The
limits of this field of sharp focus, i.e. depth of
field, vary with the aperture.
The depth of field available at any given f/stop can
be read off the depth-of-field scale on both sides
of the central index. As an example, the rings in
the illustration indicate how to read the depth of
field scale at an aperture of/l 1.
Depth-of-Field
Preview
Depth-of-field can be visually checked on the
focusing screen. The diaphragm can be stopped
down to the preset aperture from its normally
wide open position simply by pushing the depth-
of-field preview lever downwards until it locks.
To reopen the diaphragm, depress the lower part
of the lever.
