Press Set Button again to confirm the setting.

Press function button 2 to adjust the Sl/S2 mode

Sl Optical control unit setting
In M manual flash mode, theSl function can be used and the flash unit can function as an optical secondary flash. It will fire synchronously when the main flash fires, the same effect as that obtained by the use of radio triggers. This helps the photographer create multiple lighting effects.

S2 Optical control unit setting
In M manual flash mode, the S2 function can be used and the flash unit can function as an optical 52 secondary flash. In this mode, it will ignore the pre-flash emitted by the TTL flash and will only fire in response to the second flash from the main unit.
Note: Sl and S2 optical triggering is only available in M manual flash mode.

Multi: Stroboscopic Flash

The term stroboscopic flash relates to a rapid series of flashes being 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.

Press the button so that displays.
Set the flash frequency and the number of flashes.
- Press the Function Button 1 to select the number of flashes. Turn the Select Dial to set the value.
- Press the Function Button 2 to select the flash frequency. Turn the Select Dial to set the value.
Turn the Select Dial to set the flash output. Press SET Button to confirm and all settings will be displayed.

Calculating the Shutter Speed

During a 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 deterioration of the flash head, do not use the 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 flash may stop flashing automatically. This is to protect the flash head. Should this happen, please allow the camera to rest for 15 minutes.
Stroboscopic flash is most effective with a highly reflective subject against a dark background.
It is recommended to use a tripod and a remote control.
A flash output of 1/1 and 1/2 cannot be set for stroboscopic flash mode.
Stroboscopic flashes can be used with the “bulb” function.

If the flash count is displayed as –, the flash will fire continuously until the shutter release or the battery is exhausted. The number of flashes will be limited as shown in the table below.
Maximum number of strobe flashes

Wireless Flash Shooting: Wireless (2.4G) Transmission

Other Applications

Sync Triggering
The Sync Cord Jack is a <1>2.Smm connector. Insert a trigger plug here and the flash will be fired in sync with the camera shutter.

Auto Focus Assist Beam

In low-brightness or low-contrast shooting situations, the flash’s built-in autofocus assist lamp turns on to make autofocusing easier.
When focusing is difficult, the red autofocus assist light comes on.
To turn off the autofocus function, set “AF” to “OFF” in C.Fn.
If the user finds that the assisted focus light is not on when using it, it is because the camera is already accurately focused.

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 commonly known as a ‘bounce flash’.
Position the flash head to set the bou nee direction.
If the wall or ceiling is too far away, the bounced flash might be too weak and result in underexposure
The wall or ceiling should be a plain, white color for high reflectance. If the bounce surface isn’t white it will result in “off color” photos.

ZOOM: Set the flash coverage

The flash coverage can be set automatically or manually. It can be set to match the lens focal length from 20mm to 200mm. In auto zoom, the focal length changes with the camera’s zoom lens to provide the best flash effect.

In Manual Zoom mode, press the button.
