Calculating the Shutter Speed
During stroboscopic flash, the shutter remains open until the fir-
ing 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 frequen-
cy 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 succes-
sion. 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 camera flash.
• Stroboscopic flash is most effective with a highly reflec-
tive subject against a dark background.
• Using a tripod and a remote control is recommended.
• Stroboscopic flash can be used with“

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