Electronic Flash Pictures
This camera has a built·in flash synchronization socket (X contact)
.
When
you shoot titles or in single-frame shooting for animation films, an
electronic flash
unit
can
be
used.
When
you
use an electronic
flash, the aperture must be controlled manually. The proper flstop
number
_
is calculated by dividing the guide number by the distance
between the light source and the
subject.
Set the proper flstop according
to the guide numbers as listed in the instruction book or on the calculation
panel of the electronic flash. Be sure to use the same unit of measurement
for both the guide numbers and the shooting distances. For example, if the
shooting distance is in feet, the guide number should be in feet. Do not
mix meters and
feet.
• It is recommended to select the aperture opening between f/S.6 and fIll
to get the best
results.
• Set the variable shutter
control
ring at
"
OPEN". Otherwise, you will not
be able to shoot with synchronized flash
.
Shutter speed is approximately
1/43 second, but actual exposure is the same as the flash period of the
electronic flash.
When using an electronic flash unit, be specially careful in fixing the
exposure
setting,
because the still camera has a light requirement for one
single picture, whereas the 8mm cine camera requires the same light
intensity from the flash unit for successive
frames.

about 1.S cartridges of Super 8 film. Keep th is in mind
