Flash Mode: MULTI Flash (stroboscopic)
With stroboscopic flash, a rapid series of flashes is fired. It can be used
to capture multiple images of a moving subject in a single photograph.
You can set the firing frequency (number of flashes per sec. expressed
as Hz), the number of flashes, and the flash output power.

• Calculating the Shutter Speed
During stroboscopic flash, the shutter remains open until the firing
stops. Use the formula below to calculate the shutter speed and set it
on the camera.
• Number of Flashes / Flash Frequency = Shutter
Speed
For example, if the number of flashes is 10 and the firing frequency is
5 Hz, the shutter speed should be at least 2 seconds.
• To avoid overheating and deteriorating the flash head, do not use
stroboscopic flash more than 10 times in succession
• After 10 times, allow the Speedlight to rest for at least 15 minutes.
If you try to use the stroboscopic flash more than 10 times in
succession, the firing might stop automatically to protect the
flash head. If this happens, allow at least 15 minutes’ rest for the
Speedlight.
• Stroboscopic flash is most effective with a highly reflective subject
against a dark background
• Using a tripod and a remote control is recommended.
• A flash output of 1/1 and 1/2 cannot be set for stroboscopic flash
• Stroboscopic flash can be used with “bulb”
