Depth-of-freld
Depth-of-field
-
the amount
ofacceptable
sharpness
pro-
duced
at a given
aperture
and focus
setting
-
can
be cal-
culated
as
in
the following
example:
The
aperture
has
been
set at f/ll
and
the focus
at 3
me-
tres. By
reading
across from
the
relevant
aperture
mark-
ings
on
the depth-of-field
scale
on
either
side ofthe
cen-
tral index
to
the
focusing
distance
scale, you
can
see
the
extent
of the
sharp zone.
In
this example
the depth-of-
field
ranges
from
approx
.2 mto
7 m.
There
are
two tables
at the
end of
the illustration
section
of this
manual
that describe
the
depth-of-field
produced
by the various
combinations
of aperture
settings
and fo-
cus settings
regarding
45mm
and 90mm
lenses.
For
ex-
1mple,
when
focusedat2mand
set at f/8,
the depth-of-
field
extends from
l.6lto
2.66
m with
the 45
mm lens
and
from
1.89
to2.l3
with the
90 mm
lens.
See
separate
user
manual
for
