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.
