B) Depth-of-field
Two scales corresponding to lens aperture stops are
indicated on each side of the line and dot index on the
depth-of-field scale (see figure 20). These figures are
the limits in which the photograph will be in sharp
focus. When lens is focused and diaphragm set, limits
of depth-of-field can be read on the distance scale.
Example: If focusing indicates a distance of 6 feet (1.8m)
with an aperture of f:16, your photography
should be in focus from 4 V 2 feet (1,35m) to
10 feet (3m) (see figure 20). If you chose an
aperture of f:4, your picture will be in focus
only from 5 V 2 feet (1,65 m) to 7 feet (2,1m).
C) Self-timer
Proceed normally for focusing as well as for calculating
adjustments of the shutter speed and of the aperture
of the lens. Cock the shutter and the self-timer mecha¬
nism by turning completely down the self-timer lever
(see figure 21). Shutter will be released about 9 sec¬
onds after depressing the self-timer button.
