will
usually
lose 2
~
3
apertures
of
light (f-stops), even when
th
e surfa
ce
is white. Therefo
re
, when a
bounce
fl
ash photo
is
taken
in
TTL mode, it is
re
commended that a larger aperture
be
selected.
• As exposure in bounce lighting is a
factor bas
ed
upon distance,
fi
rst from
th
e
fl
ash to t
he
reflected surface, then
to the subject and fina
ll
y back to the
camera, the relationship
be
tween the
aperture setting used and the adjust-
able distance range changes accord-
ingly, depending upon the distances
involved and quality of the re
fl
ec
ti
ve
surface selected.
• The use of a white surfa
ce
as
much
as
possible for bounce lighting effects ,
will result
in
th
e best overall reflective
light
level.
Please
note
that in colo
photography, when a colored surface
is u
sed
for
bounce
lightin
g, it
will
reflect its color on the subject. @
• When the SUNPAK PZ4000AF is set
to any bounce lighting position, dis-
tance is not displayed.
• Please do not turn off the PZ4000AF
w
hil
e releasing the shutter.
• When the PZ4000AF does not wor
k,
please set
th
e switch
on
the camera
to
"OFF" and then resume the operation.
•
Depending
on the
typ
e of the
lens
used, the distance indicator may not
work.
