To set the ASA/ISO film speed, turn the dial until the
number corresponding to the film speed is opposite the
ASAIISO film speed index
.
Set the film speed
to
the "W"
index mark
@
when the Wide-Flash Adapter SW-5

For Automatic Operation
With the Sensor Unit SU-2 attached to the Speedlight
SB-14, you can shoot on Automatic. Three usable
£/stops
are indicated by the thick color-coded lines after you set
the
ASAIISO
film speed on the
dial
.
For example, if
you
are using
ASAIISO
100 film, you
can
select either £/4,
£/5
.6
or
£/8.
In selecting the
£/stop,
the
flash-to-subject distance, recycling time, and depth of
field are important factors.
• Flash-to-subject distance
The thick color-coded lines indicate the range of flash-to-
subject distances for automatic shooting as well as the
usable £/stops.
Each
distance
range
is constant regardless
of the film
speed
set on the dial.
The
orange
line
indicates
a range from 0.6m to 8m (2 to 26 ft.), the yellow from
0.6m to 5.6m (2 to 18 ft.), and the blue from 0.6m to 4m
(2
to 13
ft .). So, for example, with
ASAIISO
100 film and
