Flash Mode — TTL Autoflash

This flash has three flash modes: TTL, Manual (M), and Multi (Stroboscopic). In TTL mode, the camera and the flash will work together to calculate the correct exposure for the subject and the background. In this mode, multiple TTL functions are available: FEC, HSS, second curtain sync, modeling flash.

Press < MODE > Mode Selection Button and three flash modes will display on the LCD panel one by one with each pressing.
TTL Mode
Press < MODE > Mode Selection Button to enter TTL mode. The LCD panel will display.
- Press the camera release button halfway to focus. The aperture and effective flash range will be displayed in the viewfinder.
- When the shutter button is fully pressed, the flash will fire a preflash that the camera will use to calculate exposure and flash output the instant before the photo is taken.

FEC: Flash Exposure Compensation
With FEC function, this flash can adjust from -3 to +3 in 1/3rd stops.
It is useful in situations where minor adjusting of the TTL system is needed based on the environment.
Setting FEC:

Press Function Button 2 Press the <+/-> button. The icon < > and flash exposure compensation amount will be highlighted on the LCD panel.
Set the flash exposure compensation amount.
● Turn the Select Dial to set the amount.
● “0.3”means 1/3 step, “0.7”means 2/3 step.
● To cancel the flash exposure compensation, set the amount to “+0”.
Press Set Button again to confirm the setting.

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.

Press Function Button 2 < SYNC> so that < > is displayed.
Set the camera shutter.

With high-speed sync, the faster the shutter speed, the shorter the effective flash range.
To return to normal flash, press < SYNC> button again. Then < > will disappear.
Multi flash mode cannot be set in high-speed sync mode.
Over-temperature protection may be activated after 15 consecutive high-speed sync flashes.

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 2 < SYNC> button so that < > is displayed on the LCD panel.
Set the camera shutter.

Note: The second curtain sync function can only be achieved when the flash is attached on the camera (non transmitter mode).

M: Manual Flash

The flash output is adjustable from 1/1 full power to 1/256th power in 1/10th stop increments. To obtain a correct flash exposure, use a hand-held flash meter to determine the required flash output.

Press < MODE > button so that < M > is displayed.
Press the <+/-> button and turn the Select Dial to choose a desired flash output amount.
Press Set Button again to confirm the setting.

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.
S1 and S2 optic triggering is only available in M manual 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 button so that < Multi> is displayed.
Set the flash frequency and flash times.
● Press the Function Button 2 to select the flash times. Turn the Select Dial to set the number.
● Press the Function Button 3 to select the flash frequency. Turn the Select Dial to set the number.
Press the <+/-> button and turn the Select Dial to choose a desired flash output.
● 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:

Flash| Hz output| 1| 2| 3| 4| 5| 6-7| 8-9
---|---|---|---|---|---|---|---|---
1/4| 8| 6| 4| 3| 3| 2| 2

Wireless Flash Shooting: Radio (2.4G) Transmission

You can set up five receiver groups for TTL autoflash shooting. With TTL autoflash, you can easily create various lighting effects.
Any flash settings for the receiver units(auto flash, manual flash and stroboscopic flash) on the transmitter flash in TTL mode will be automatically sent to the receiver units. So the only thing you need to do is to set the transmitter unit for each receiver group without any operation for the receiver units at all during the shooting.
This flash can work in TTL /M /Multi/ OFF flash modes when set as a transmitter unit.

Note:

Even with multiple receiver units, the X series flash trigger can control all of them via wireless.
In this user manual, “transmitter unit” refers to the camera flash on a camera and “receiver unit” will be controlled by the transmitter unit.

Positioning and Operation Range (Example of wireless flash shooting)

Autoflash Shooting with One Receiver Unit
Use the supplied mini stand to position the receiver unit.
Before shooting, perform a test flash and test shooting.
The transmission distance might be shorter depending on the conditions such as positioning of receiver units, the surrounding environment and whether conditions.

Other Applications

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.
Modeling Flash
If the camera has a depth-of-field preview button, pressing it will fire the flash continuously for 1 second. This is called modeling flash. It enables you to see the shadow effects on the subject and the lighting balance. You can fire the modeling flash during wireless or normal flash shooting.
To avoid overheating and deteriorating the flash head, do not fire the modeling flash for more than 10 consecutive times. If you fire the modeling flash 10 consecutive times, allow at least 10 minutes’ break for the camera flash.
Auto Focus Assist Beam
In poorly-lit or low-contrast shooting environments, the built-in auto focus assist beam will automatically light on to make it easier for autofocus. The beam will light up only when autofocus is difficult and get out as soon as the autofocus becomes correct.
If you want to turn off the auto focus assist beam, set the “AF” to “OFF” on the C.Fn settings.
If you find the auto focus assist beam does not light up, this is because the camera has got a correct autofocus.

Position	Effective Range
Center	0.6~10m / 2.0~32.8 feet
Periphery	0.6~5m / 2.0~16.4 feet

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.

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 is not white, a color cast may appear in the picture.

ZOOM: Setting the Flash Coverage
The flash coverage can be set automatically or manually. It can be set to match the lens focal length from 19-69mm (APS format) or 28-105mm (135 format).
In Manual Zoom mode, press the button.

Turn the Select Dial to change the flash coverage.
If < A > is displayed, the flash coverage will be set automatically.
