MD (synchronization with motor drive)
At
the motor drive (MD) setting, the S8
-16
is able to
recycle fast enough
to
sy
nchronize with a motor-driven
camera firing continuously
up
to
four frames per second.
It
is
possible
to
take
up
to
eight flash pictures
in
rapid
succession
in
this way.
At
the MD
se
tting, only the main
flash head fires
and
the light output
is
approx. one-
sixteenth that of the flash unit's
ma
xi
mum power.
Like
the M setting,
thi
s
se
tting
is
also for manual operation;
therefore, the exposure should
be
calculated manually
using the exposure calculator dial or guide number
equation shown
on page
30.
Note: As sufficient power
is
required for
the
flash unit
to
synchronize
with
a motor drive, use the newest and freshest batteries whenever
possible. For the same reason, avoid tripping the shutter immediately
aft
er
the ready-light comes
on
. but wait for at least 30 seconds before
beginning the motor drive sequence.
