following formula to calculate the shutter speed required to capture the full sequence
of flashes:
Number of flashes / Firing 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 sec.
Note:
Stroboscopic flash is most effective with a highly reflective subject against a dark background.
Using a tripod and a remote switch is recommended.
A flash output of 1/1 or 1/2 cannot be set for stroboscopic flash.
Stroboscopic flash can be used with “
buLb
”.

Flash Output
Note:
To avoid overheating and deteriorating the flash head during stroboscopic flash, do not use
stroboscopic flash more than 10 times in succession.
8. Hi-Speed Sync Triggering
To enter mode, press <
> button (18) and hold
for 2 seconds.
To exit mode, press Mode Selection Button (11) or
press <
> button (18) and hold for 2 seconds again.
In hi-speed sync triggering mode, you can use a hi-
speed sync trigger to have your flash unit synchronized
When “OF” is shown on the LCD display, it means no flash output and flash firing is
turned off.
3. ZOOM: Setting the Flash Coverage
The flash coverage can be set to match the lens focal length from 24 mm to 105 mm.
Press <
> button (12) and rotate Select Dial (14) to change the flash coverage.
4. M Mode: Manual Mode
Press MODE Selection Button (11) to enter M mode. In this mode, you can set the
flash unit onto your camera hot shoe or your trigger hot shoe for firing.
Before shooting, adjust the flash power output. When the camera's shutter is
pressed, the flash will fire synchronously. Slave triggering mode is not available in M
mode.
5. S1 Mode: S1 Slave Triggering Mode
Press Mode Selection Button (11) to enter S1 mode. In this mode, the flash unit can
function as a slave flash for creating multiple lighting effects. It is respectively
applicable to manual flash environment.
In S1 mode, the flash unit will fire synchronously when the master flash fires, the
same effect as that by the use of radio triggers.
6. S2 Mode: S2 Slave Triggering Mode
Press Mode Selection Button (11) to enter S2 mode. In this mode, the flash unit can
function as a slave flash for creating multiple lighting effects. It is applicable when
using a TTL master flash.
In S2 mode, the flash unit will ignore a single “preflash” from the master flash and will
only fire in response to the second, actual flash from the master.
7. RPT Mode: Stroboscopic Flash
Press Mode Selection Button (11) to enter RPT mode (Multi/Stroboscopic flash).
With stroboscopic flash, a rapid series of flashes is fired. It can be used to capture
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.
For setting procedures, see the following:
1. Press the Mode Selection Button (11) so that “RPT” is displayed.
2. Press Set Button (15) to select the item to be set. The item blinks.
3. Rotate Select Dial (14) to set a desired number.
Calculating the Shutter Speed
During stroboscopic flash, the shutter remains open until the firing stops. Use the
Fn
ZOOM
Note:
When setting the flash coverage, make sure it covers the lens focal length so that the
picture will not have a dark periphery.
