Electronic Flash Pictures
This camera has a built-in flash synchronization socket (X contact). When
you take a title or animation film in single-frame shooting, an electronic
flash unit can be used. When you use an electronic flash, the aperture must
be controlled manually. The proper f/stop number is calculated dividing
the GN (guide number) by the distance between the light and the subject.
Set the proper f/$top according to the GN listed in the instruction book or
on the calculation panel of the electronic flash. In this case, use the same
unit for both the GN and shooting distance. For example, if the shooting
distance is in feet, the GN should be in feet.
Do not mix meters and feet.
• Set the variable shutter control ring at "O". Otherwise, flash syn­
chronized shooting cannot be performed. Shutter speed is approximately
1/43 sec. But actual exposure is the same as the flash period of the
Speedlite.
If using an electronic flash unit, be especially careful in fixing the exposure
setting, because the still camera has a light requirement just for a single
picture, whereas the 8mm cine camera requires the same light intensity
from the flash unit for successive frames.
Better results are obtained when the Speedlite with its built-in electric
circuit stabilizer is used. When using an electronic flasn unit without the
stabilizer, keep in mind that the camera will function immediately after the
pilot lamp lights up.
Open the aperture one f/stop or a half, or use the AC power source,
according to the electronic flash you use.
• A discharge tube of an electronic flash is said to bear about 5,000
operations, that is, about 1.5 cartridges of Super 8 film. Keep this in mind
in single-frame shooting,
• A flash mounting adapter will be marketed soon.
