changes. The automatic system is switched off and the previously determined exposure
time is triggered with normal handling of the shutter.
DEPTH - OF - FIELD
In addition to the exposure, the diaphragm also determines the zone of sharpness in front
of, and behind, the focused distance. Small diaphragm settings (stopping down)
appreciably increase this zone of sharpness, or depth-of-field. It also increases the farther
away the subject is from the camera. Its extent for the respective diaphragms is
indicated on the depth-of-field scale.
In addition, the depth-of-field scale next to the focusing ring (fig. 7 page 14) with the
distance numbers indicates approximate depth-of-field. As an example: if a distance of 3
m. was chosen; the boundary lines to the left and right of the triangular index mark show
the sharp focus zone on the distance scale: at f/11 it extends from 2 m. to 5.30 m. The
exact depth-of-field zones resulting from these various settings are found in the table on
p. 22.
