Depth
of
field is the
rang
e be-
tween the ne
ar
est and farth
es
t
distances which
ar
e
in
acceptable
focus at differe
nt
lens aperture
s.
If
you
want
to
know
how
great
the
depth
of
field
is
at a certain
aperture,
look
at
the depth-of-field guide.
In
the
above
photograph,
the distance scale
is
set at
5 meters
..
.
the
lens is focused
on
a subject 5 meters
away. The calibrations
on
each side
of
the
distance
index correspond
to
the
diaphragm setting and in-
dicate
the
range
of
in-focus distance for different lens
apertures.
For
example, if the lens opening
of
f/8
is
to
be used,
the
range
on
the
distance scale ring cov-
ered
between
the
figures 8
on
that
depth-of-field
guide indicates
the
area in focus
at
the lens opening.
You will
note
from the depth-of-field guide in the
photograph
that
the
range from approximately 10
to
25 feet
is
in focus.
Note
that
as
the
lens aperture
change,
the
effective
depth
of
field also changes.
For
the
depth
of
fields
at
different apertures and
distances, refer
to
the next page.
