2) Set the zoom setting knob Turn the zoom setting knob at the center on the dial until the zoom setting index is opposite the same letter as you selected in setting the zoom head. For example , if you set the zoom head at T for a 85mm lens, the zoom setting knob must also be set at T. Note: The W, setting on the dial is used when the wide-flash adapter is attached to the flash unit with the zoom head set at WI. 3) Determine the exposure Depending on which shooting mode you 've selected, read off the usable f/stop(s) from the dial. In either the TTL or non-TTL automatic mode, more than one f/stop is usable. When choosing an aperture , make sure that your subject is within the auto shooting range indicated by the color-coded lines. The larger the aperture (the smaller the f-number) you select , the greater the maximum shooting distance, whereas the smaller the aperture (the larger the f-number), the less the maximum shooting distance. If the subject distance remains the same , the larger the aperture you select, the less depth of field in the final photograph; however, the recycling time is shorter. On the other hand , the smaller the aperture , the greater the depth of field , but the recyc ling time is longer. Therefore , in choosing an flstop , all these factors should be taken into consideration . 25

2)
Set
the
zoom
setting
knob
Turn
the zoom setting knob at the center
on
the dial until
the zoom setting index is opposite the same letter
as
you
selected
in
setting the zoom head. For example,
if
you
set the zoom head at T for a 85mm lens, the zoom set-
ting knob must also
be
set at
T.
Note:
Th
e
W,
setting on the dial
is
used when the wide-flash adapter
is
attached to the
fl
ash unit with the zoom head set at
WI.
3)
Determine
the
exposure
Depending
on
which shooting mode you '
ve
selected,
read off the usable
f/stop(s)
from the dial. In either the
TTL
or non-TTL automatic mode, more than one
f/stop
is
usable. When choosing
an
aperture, make sure that your
subject
is
within the auto shooting range indicated by the
color-coded lines.
The
larger the aperture (the smaller
the f-number)
you
select, the greater the
ma
ximum
shooting distance, whereas the sma
ll
er the aperture (the
larger the f-number), the less the maximum shooting
distance. If the subject distance remains the same, the
larger the aperture you select, the less depth of field
in
the final photograph; however, the recycling time
is
shorter.
On
the other hand, the smaller the aperture, the
greater the depth of field , but the recyc l
ing
time
is
longer.
Therefore,
in
choosing
an
flstop, all these factors should
be
taken into consideration.
