With stroboscopic flash, a rapid series of flashes is fired. It can be used to capture a 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.

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.

Display Flash Duration

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.
