Depth
of
field
-
with all SINAR
models
Afier
locating
and
focusing
on
the
plane
of
maximum
sharpness,
stop
down
the
lens
as
far as
necessary
to extend
sharpness
at
right angles
to
this
plane.
The simplest
and
quickest way
is with the
SINAR
depth
of
field
scale:
-
At
full aperture
focus
on
the most
distant
subject
point
required
sharp
(i.e.
focused
with the
shortest
camera
extension).
-
Without
changing
the
focus setting,
zero
the
depth
of field
scale
(arrow
against
index).
-
At
full aperture
focus
on
the nearest
subject
point
required
sharp
(i.e.
focused
with
the
longest camera
extension).
-
Read
off
the
working
aperture
now shown
on
the scale
(e.9.
here
'f/22'1
and
set
this
on
the lens.
-
Turn
the
fine
focusing
drive
2 back
through
two lens stop
intervals
on
the
depth
of
field scale
(shortening the camera
extension
-
to
f/'l 1
in this
case).
This
then
yields
optimum
focus.
