-CONTROLS IN DETAll-continued--------- For manual (M) operation After setting the ASA/ISO film speed and zoom setting knob on the exposure calculator dial , focus on the subject; then look at the lens and read off the focused distance 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. 30 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 : = flstop guide number 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. Therefore, if the subject is 20 ft . away, divide 52 by 20 to get approx . f/2.B.

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.
