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 underexposure, the
amount is user adjustable. This function helps get correct exposure especially
in shooting moving objects or when environmental rights are complex.
-
Press function button 3 1 < >. The icon < > and the exposure bracketing amount will be highlighted on the LCD panel.

is ready before shooting.
● FEB can be used with FEC and FEL.
C.Fn You can prevent the FEB from being canceled automatically after
three photos are taken. (C. Feb ACL, Page55)
FEL: Flash Exposure Lock
FEL can lock the correct flash exposure setting for any part of the scene.
With < ETTL> displayed on the LCD panel, press the camera’s < FEL>
button. If the camera does not have the < FEL> button, press the < * >
button.
- Focus on the subject.
- Press the < FEL > button.
● Aim the subject at the center of the viewfinder and press the < FEL >
button.
● The camera flash will fire a preflash and the required flash output for the
subject is retained in memory.
● Each time the < FEL > button is pressed, a preflash will be fired and a
new flash exposure the setting will be locked. 
● 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.
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.
- ress Function Button 2 1 < SYNC > so that < > is displayed.
- Check that < > is 2 displayed in the viewfinder.
● If you set a shutter speed that is the same as or lower 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.
● Multiflash 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 trail following the subject.
The flash fires right before the shutter close.
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.
- Press < MODE > button so 1 that < M > is displayed.
- Turn the Select Dial to choose 2 a desired flash output amount.
- Press Set Button again to 3 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 the 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 ffects.
Optic S2 Secondary Unit Setting
Press < S1/S2 > button so that this flash can also function as an optic S2
secondary flash with the optic sensor in M manual flash mode. This is useful
when cameras have a 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 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 < MODE > button so 1 that < MULTI > is displayed.
-
Set the flash frequency and 2 flash times.
• Press the Function Button 2 to select the flash times. Turn the
Select Dial to set the number.

Select Dial to set the number.
-
Turn the Select Dial to 3 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 the 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 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 attaches to the camera is called the master unit, and a V1C that is
wirelessly controlled is called the slave unit.
● You can also wirelessly control the V1C set as the slave unit with the
transmitter X1T-C (sold separately). For details on setting the master unit
functions, see the transmitter’s instructions.
Using a flash (master/slave) with a radio transmission wireless shooting
function makes 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
master unit to .
Positioning and Operation Range (Example of wireless flash shooting)
● Use the supplied mini stand to position the slave unit.
● Before shooting, perform a test flash and test shooting.
● The transmission distance might be shorter depending on the conditions such
as positioning of slave units, the surrounding environment and weather
conditions.
Wireless Multiple Flash Shooting
You can divide the slave units into two or three groups and perform an E-TTL
II autoflash while changing the flash ratio (factor). In addition, you can set
and shoot with a different flash mode for each firing group, for up to 4
groups. 
* The flash mode settings are
indicated only as an example
Wireless Settings
You can switch between normal flash and wireless flash. For normal flash
shooting, be sure to set the wireless setting to OFF.
