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.
To avoid overheating and deteriorating the flash head, do not use stroboscopic flash
more than 10 times in succession. After 10 times, allow the camera flash 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 flash.
● 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”.
● 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.

Flash duration refers to the length of time that from flash’s firing to reach the half peak at
maximum. The half peak at maximum is usually expressed as t=0.5. In order to provide the
photographer with more concrete data, this product adopts t=0.1. The difference between t=0.5
and t=0.1 is shown in the following picture.
● The flash duration will only be displayed on the LCD panel in M mode.
