Multi: Stroboscopic Flash
● With high-speed sync, the faster the shutter speed, the shorter the effective flash range.
● Multi flash mode cannot be set in high-speed sync mode.

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 with 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.
● 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.
● If the number of flashes is displayed as “--”, the firing will continue until the shutter closes or the battery is
exhausted. The number of flashes will be limited as shown by the following table.
