Minolta X-300 - Depth of Field

DEPTH
OF
FIELD
-A-
-B-
When a
lens is focused on a
given
subject, there
is a certain
range
behind
and
in front of the subjqct
which
appears sharp.
This
range is
called
"depth
of
field",
and
it varies
according to the
aperture set:
large
apertures
(e.g.,
f
l1
.7
|
yield
a
shallow depth
of
f
ield
rendering the
background out
of
focus
(example
A);
smalf
apertures
le.g.,
f
l22l
give
greater
depth
of
field
with
sharper
background
(example
B). Tfre
depth
of
field can be
checked
on
the
lens'
depth-of-field
scale as
shown.
Depth of
field also
varies
with
subject
distance:
when the
lens is
focused
on a
close subject,
the
depth of
field is shallow; when
focused
on
a distant
subject, the
depth
of
f ield is
greater.
