LINIDE-ANGLE/TELEPHOTOLENSADAPTORS HOWTOATTACHTHEADAPTORS Slide either adaptor into the slots at the top and bottom of the flash head, making sure to push it all the way in until it is centered over the flash head. 18 WIDE-ANGLAEDAPTOR( AFW1) Designed principally for ultra-wide-angle lenses down to 24mm, this adaptor also offers improved results with 28mm and 30mm lenses. Auto Flash: When the wide-angle adaptor is employed maximum auto flash range is reduced to 5 meters (16.4 ft.) at the RED auto setting and 2.5 meters (8.2 ft.) at the GREEN auto setting. Index the ASA film speed as for normal auto exposures, but use the respective "W" index line of both RED and GREEN auto modes to determine the f-number. Manual Flash: To compensate for manual f exposures with the wide-angle adaptor index, halve the ASA film speed on the ASA film speed index on the flash unit's control panel (if you are using ASA 100 film, for example, align the number 50 with the white index line). Then, choose the f-number opposite the subject distance in the same manner as with manual flash when the adaptor is not used.

WIDE-ANGLE
ADAPTOR
( AFW1)
Designed
principally
for
ultra
-wide-angle
lenses
down
to
24mm,
this
adaptor
also
offers
im-
proved
results
with
28mm
and
30mm
lenses.
Auto
Flash:
When
the
wide-angle
adaptor
is
employed
maximum
auto
flash
range
is
reduced
to
5
meters
(16.4
ft.)
at
the
RED
auto
setting
and
2.5
meters
(8.2
ft.)
at
the
GREEN
auto
setting.
Index
the
ASA
film
speed
as
for
normal
auto
exposures,
but
use
the
respective
"W"
index
line
of
both
RED
and
GREEN
auto
modes
to
determine
the
f-number.
Manual
Flash:
To
compensate
for
manual
f
exposures
with
the
wide-angle
adaptor
index,
halve
the
ASA
film
speed
on
the
ASA
film
speed
index
on
the
flash
unit's
control
panel
(if
you
are
using
ASA
100
film,
for
example,
align
the
number
50
with
the
white
index
line).
Then,
choose
the
f-number
opposite
the
subject
distance
in
the
same
manner
as
with
manual
flash
when
the
adaptor
is
not
used.
