The aperture setting
not
only
controls the amount
of
light
that
reaches the
film,
but also
determines
"depth
of
field,"
which is the
range of
sharp
focus
in front of and
beyond the
subject focused upon.
The illustrations on this
page
show
you
the
difference
in
range of sharp
focus when the smallest
and largest
apertures
are used at the
same distance
settings.
The
camera in the
illustration
is focused on 8 feet.
By reading
between identical
f: numbers on the
depth of
field scale,
you
see that
if
f:22is
used, the
range ofsharpness
extends
from 4 feet to
infinity. When
f:2.8 is used, everything
from 7 to 9 feet
is in focus.
By turning the
rangefinder dial
you
can watch the
depth
of
field
for
any one aperture change
as the distance
scale
changes.
Consulting the
handy
depth of field scale
helps
find
the
best combination
of aperture and
distance
setting.
