Calculating the shutter speed
To ensure that the shutter remains open until all stroboscopic firing is finished, calculate a
shutter speed to set on the camera as follows.
Flash count ÷ flash frequency = shutter speed
For example, when flash count is set to 10 (times) and flash frequency to 5 (Hz), set the
shutter speed to at least 2 sec.
Caution
To avoid wearing out or damaging receiver flash heads from overheating, do not
use stroboscopic flash repeatedly more than 10 times. After 10 shots, stop using
the flash for at least 15 min.
Shooting more than 10 times may activate a safety function and restrict flash firing.
Stop using the flash for at least 15 min.
Note
Stroboscopic flash is most effective for subjects with high reflectance against a
dark background.
Using a tripod and remote switch is recommended.
Stroboscopic flash output cannot be set to 1/1 or 1/2.
Stroboscopic flash is also available when the camera is in <bulb( )> shooting
mode.
A flash count display of “----” indicates that the flash will fire continuously until the
shutter closes or the charge runs out, with the maximum flash count as listed in
Maximum continuous flash count.
High-speed sync ( ) and second-curtain sync ( ) are not available with
stroboscopic flash.
