Sensor Unit SU-101 (Optional)
Mounting the SU·101 on the camera
: Turn
the sensor
unit's locking
wheel counterclockwise as far as
it
will
go, slip
the unit
's
mounting foot into
the camera's
accessory shoe,
and turn
the
locking
wheel clockwise
to tighten it.
In combination with the optional Sensor Unit SU-101,
the S8-102 provides non-TTL automatic flash
exposure
control.
With the S8-102
's
shooting
mode
selector
switch
®
at "AUTO,"
the Sensor Unit SU-101 reads
the
light reflected back from the
subject while the speed-
light is firing and tells the
speedlight
to
turn
itself
off
when the light output is
sufficient
for
correct exposure.
The selector dial on the back of
the
SU-101
allows
one
of
two aperture
settings
to be
selected.
Normally,
the SU-101
is
attached to the
camera's
accessory
shoe.
However, when a plastic frame finder
or optical underwater viewfinder
is
mounted
on the
camera's accessory
shoe,
the optional
sensor
holder
is
used to attach the Sensor Unit SU-101 to the
speedlight
bracket.
Mounting the SU·101 on the
bracket: Insert the
sensor
holder positioning pin
@
on
the bracket
into
the
sensor
holder,
then
screw
the
sensor
holder's
screw
into the
sensor
holder
socket
@
on
the
bracket. To
attach
the SU -101
to the sensor
holder,
follow
the same
procedures
as when attaching the
SU-101 to the
camera
's
accessory
shoe
.

Synchronization Speed
The
shutter speed
at
which the
S8-102
synchronizes
with
a camera depends upon the
camera
being
used.
The
table
shows
the flash
sync speeds
of
various cameras.
80th the Nikonos -V
and
Nikonos IV-A
cameras auto-
matically
switch
to the proper
synchronization speed
when the

's
power
switch
is
turned
on
;
when the
switch
is turned

the
automatic switchover
