setting will be locked.
High-Speed Sync
High Speed Sync (FP flash) enables the flash to synchronize with all camera shutter speeds. This is
convenient when you want to use aperture priority for fill-flash portraits.
1、Press Function Button 4 < > so that < > is displayed.
2、Check that < > is displayed in the viewfinder.
If the subject is too far away and underexposure, the < > icon will blink in the
viewfinder. Move closer to the subject and try the FE lock again.
If <ETTL> is not displayed on the LCD panel, FE lock cannot be set.
If the subject is too small, FE lock might not be very effective.
If you set a shutter speed that is the same as or slower than the camera’s
maximum flash sync speed, < > will not be displayed in the viewfinder.
With high-speed sync, the faster the shutter speed, the shorter the effective flash
range.
To return to normal flash, press < > button again. Then < > will
disappear.

Second-Curtain Sync
With a slow shutter speed, you can create a light train following the subject. The flash fires right
before the shutter closes.
Press function button 4 < > button so that < > is displayed on the LCD panel.
M: Manual Flash
The flash output is adjustable from 1/1 full power to 1/128th power in 1/3rd stop increments. To
obtain a correct flash exposure, use a hand-held flash meter to determine the required flash
output.

←Figures displayed when increasing flash output level
Optic S1 Secondary Unit Setting
In M manual flash mode, press < S1/S2> button so that this flash can function as an optic S1
secondary flash with optic sensor. With this function, the flash will fire synchronously when
the main flash fires, the same effect as that by the use of radio triggers. This helps create
multiple lighting effects.
Optic S2 Secondary Unit Setting
Press < S1/S2> button so that this flash can also function as an optic S2 secondary flash with
optic sensor in M manual flash mode. This is useful when cameras have pre-flash function. With
this function, the flash will ignore a single “preflash” from the main flash and will only fire in
response to the second, actual flash from the main unit.
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.
1. Press <MODE> button so that <MULTI> is displayed.
2. Turn the Select Dial to choose a desired flash output.
3. Set the flash frequency and flash times.
● Press Function Button 3 < > button to select the flash times. Turn the Select Dial
to set the number.
S1 and S2 optic triggering is only available in M manual flash mode.

● Press Function Button 4 < > button to select the flash times. Turn the Select Dial
to set the number.
● After you finish the setting, press <SET> button and all the settings will be displayed.
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 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.

Maximum Stroboscopic Flashes:
1 2 3 4 5 6-7 8-9
