C.Fn Disabling Auto Power Off function is recommended when the flash is used off camera. (C.Fn-STBY, Page 55)
C.Fn Receiver Auto Power Off Timer is set to 60 minutes by default. Another option “30 minutes” is available. (C.FnRX STBY, Page 55)
Flash Mode–E-TTL Autoflash
This flash has three flash modes: E-TTL, Manual (M), and Multi (Stroboscopic). In E-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, FEB, FEL, HSS, second curtain sync, modeling flash, control with the camera’s menu screen. * Press < MODE > Mode Selection Button and three flash modes will display on the LCD panel one by one with each pressing.
ETTL Mode
Press < MODE > Mode Selection Button to enter E-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 pre-
flash 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:
1 Press Function Button 2 Press the <+/-> button. The icon < > and flash exposure compensation amount will be highlighted on the LCD panel.
2 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”.
3 Press Set Button again to confirm the setting.
– 41 –

FEB: Flash Exposure Bracketing

You can take three flash shots while automatically changing the

flash output for each shot from -3 to +3 in 1/3rd stops. The camera

will record three images with different exposures: one exposed

according to camera calculations, one over-exposed and another

under-exposed. Over and under exposure amount is user

adjustable. This function helps get correct exposure especially in

shooting moving objects or when environmental lights are complex.

1 Press function button 3 < FEB >. The icon <

and the exposure bracketing

amount will be highlighted on

the LCD panel.

2 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.
3 Press Set Button again to confirm the setting. Then your FEC and FEB settings are displayed on the LCD panel.

FEB will be cancelled after three photos are taken.
For best results, set the camera drive mode to “single” and ensure the flash is ready before shooting.
FEB can be used with FEC and FEL. C.Fn You can prevent the FEB from being cancelled automatically after three photos are taken. (C.FnFEB ACL , Page 55)

FEL: Flash Exposure Lock
FEL can lock the correct flash exposure setting for any part of the scene. With displayed on the LCD panel, press the camera’s button. If the camera does not have the button, press the < * > button.
1 Focus the subject. 2 Press the button.
Aim the subject at the center of the viewfinder and press button.
The camera flash will fire a preflash and the required flash output for the subject is retained in memory.
Each time the button is pressed, a preflash will be fired and a new flash exposure setting will be locked.
– 42 –

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 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.
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 2 < SYNC > so that < > is displayed.
2 Check that < > is displayed in the viewfinder.
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 < 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.

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.
1 Press < MODE > button so that < M > is displayed.
2 Turn the Select Dial to choose a desired flash output amount.
3 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.

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 button so that < MULTI > is displayed.
2 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.
3 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.

Wireless Flash Shooting: Radio (2.4G) Transmission
When the camera’s shooting mode is set to a fully automatic mode or an Image Zone mode, the operations in this chapter are not available. Set the camera’s shooting mode to P/Tv/Av/M/B (Creative Zone Mode).
The V1C attach to the camera is called the transmitter unit, and a V1C that is wirelessly controlled is called the receiver unit.
You can also wirelessly control the V1C set as the receiver unit with the transmitter X1T-C (sold separately). For details on setting the transmitter unit functions, see the transmitter’s instructions.
Using a flash (transmitter/receiver) with a radio transmission wireless shooting function make it easy to shoot with advanced wireless multiple flash lighting, in the same way as E-TTL II autoflash shooting. The basic relative position and operation range are as shown in the picture. You can then perform wireless E-TTL II autoflash shooting just by setting the transmitter unit to

Using Automatic Wireless Flash with Multiple Receiver Units
When stronger flash output or more convenient lighting operation is needed, increase the number of Receiver units and set it as a single Receiver unit. To add Receiver units, use the same steps as setting “automatic wireless flash with a single Receiver unit”. Any flash group can be set (A/B/C/D/E). When the number of Receiver units is increased and the Transmitter unit flash firing is ON, automatic control is implemented to make all groups of flashes fire the same flash output and ensure the total flash output up is to standard exposure.
Press the depth-of-field preview button on the camera to fire a modeling flash.
If the Receiver unit’s auto power off function is workable, press the Transmitter unit’s test button to power it on. Please note that test firing is unavailable during the camera’s regular metering time.
The effective time of Receiver auto power off is changeable. (C.Fn-RX STBY Page 55)
By making some settings, the auto AF-assist transmitter will not blink after the Receiver unit’s flash ready indicator is lightened. (C.Fn-AF Page 55)

Using Fully Automatic Wireless Flash

The FEC and other settings that set on the Transmitter unit will also be appeared on the Receiver unit automatically. The Receiver unit does not need any operation. Use the following settings to make wireless flashes according to the same methods with normal flash shooting.

Other Applications
Sync Triggering
The Sync Cord Jack is a 2.5mm 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.
The modeling flash cannot be fired with the EOS 300 and Type-B cameras.
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.

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.
-7-120°
330°
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 28mm to 105mm.
In Manual Zoom mode, press the button. Turn the Select Dial to change
the flash coverage. If < > is displayed, the flash
coverage will be set automatically. If you set the flash coverage manually, make sure it covers the lens focal length so that the picture will not have a dark periphery.
Low Battery Warning If the battery power is low, < > will appear and blink on the LCD panel. Please replace the battery immediately.
