For manual (M) operation
After setting the ASA/ISO film speed and zoom setting
knob
on
the exposure calculator dial, focus
on
the sub-
ject; then look at
the
lens and read off the focused dis-
tance to determine exactly how far away the subject
actually
is
. Now, find the end of the color-coded line
directly above the flash-to-subject distance and read off
the f-number next to this line. Then, set this aperture
on
your lens.

Example
When using ASAIISO
100
(with the zoom head set at N
for a 35mm lens) and the subject
is
located 1.5m
(5
.0 ft.)
away, the correct aperture
is
approx. f/22. With a subject
3m
(10
ft.) away, the aperture
is
approx. fl11.
Without referring
to
the exposure calculator dial, you can
also determine the
flstop
by
using the following equation:
guide number
flstop =
flash-to-subject distance
With ASAIISO
100
film and meters (and the zoom head
set
at
N for a 35mm lens), the S8-16's guide number
is
32
.
If
the subject
is
4 m away, divide
32
by
4 to get
fiB.
Wi
th
ASAIISO
25
fi
lm and feet (and zoom head set at
N for a
35
mm lens), the guide number
is
52.
Th
erefore,
if
the subject
is
20
ft
. away, divide
52
by
20
to get approx.
f/2.B.
