a subject more than 5.6m (18 ft.) away, the only usable
f/stop is f/4.
On the other hand, the thin color-coded lines (3)with "W"
indicate the distance ranges when the wide-flash adapter
is used: from 0.6m to 5.6m (2 to 18 ft.), 0.6m to 4m (2 to
13 ft.), and 0.6m to 2.8m (2 to 9 ft.), respectively. In this
case, with ASA/ISO 100 film, if the subject is more than
4m (13 ft.) away, only f/4 can be used.
Note: With a subject more than 8m (26 it.) away — or more than 5.6m
(18 ft.) away when using the wide-flash adapter — shoot on manual.

Recycling time and depth of field
If the subject distance remains the same, the wider the
aperture you select, the faster the recycling time of the
flash unit and the greater the maximum shooting distance,
but the less the depth of field. With ASA/ISO 100 and a
subject up to 4m (13 ft.) away, you can select any one of
the three f/stops indicated, f/4, f/5.6 or f/8, taking into
consideration the recycling time or depth of field you
desire. With the wide-flash adapter attached and a sub­
ject up to 2.8m (9 ft.) away, the usable f/stops are also
f/4, f/5.6 and f/8.
