Depth
of
field
refers
to
the
range
around
the
optimum
focusing
point
of
the
subject
in
which
the
elements
at
different
distances
are
in
focus.
The
depth
of
field
in-
creases
as
the
aperture
is
closed
down,
the
focal
length
of
the
lens
becomes
shorter,
or
the
subject
is
positioned
farther
away.
The
Range
Allowed
for
Focusing
The
in
-focus
range
varies
depending
on
the
aperture
in
use.
Zoom
lenses
do
not
have
a
depth
-of
-field
scale
for
mechanical
considerations.
The
Preview
Button
If
the
lens
aperture
ring
is
set
to
a
other
than
"A"
posi-
tion,
the
depth
-of
-field
preview
can
be
confirmed
by
de-
pressing
the
preview
button.
The
aperture
you
have
set
will
be
closed
down.
With
the
preview
button
de-
pressed,
the
exposure
will
not
be
set
correctly.
