Flash Mode -- Multi:Stroboscopic Flash
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.
Press <MODE> button so
1that < > is displayed.
Turn the Select Dial to choose
2a desired 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.
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.
Number of Flashes / Flash Frequency = Shutter Speed
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 camera 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.

Other Applications
Wireless Control Function
The flash unit is built in with a Wireless Control Port so that you can
wirelessly adjust the power level of the flash and the flash
triggering.
To control the flash wirelessly, you need a FT-16S
remote control set (on-camera and on-flash). Insert its
receive end into the Wireless Control Port on the flash
and insert the transmit end into the camera hot shoe.
Settings made on the hotshoe-mounted
transmit and receive ends will
be wirelessly communicated
to the flash. Then you can
press the camera shutter
release button to trigger the
flash. You can also hold the
transmit end at hand to control
your off-camera flash.
For full instructions on the use of FT series remote control, see its user
manual.
Sync Triggering
The Sync Cord Jack is a Φ2.5mm plug. Insert a trigger plug here
and the flash will be fired synchronously with the camera shutter.
Bounce Flash
By pointing the flash head toward a wall or ceiling, the flash will
bounce off the surface before illuminating the subject. This can soften
shadows behind the subject for a more natural-looking shot. This is
called bounce flash.
To set the bounce direction, hold the flash head and turn it to a
satisfying angle.
360
-7-90
● If the wall or ceiling is too far away, the bounced flash might
be too weak and result in underexposure.
● The wall or the ceiling should be a plain, white color for
high reluctance. If the bounce surface is not white, a color
cast may appear in the picture.
Creating a Catchlight
With the catchlight panel, you can create a catchlight in the subject’s
eyes to add life to the facial expression.
Point the flash head upward
1by 90°.
Pull out the wide panel. The
2catchlight panel will come out
at the same time.
Push the wide panel back in.
