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:
Set the flash exposure

● Turn the Select Dial to set
the amount.
● “0.3”means 1/3 step,
“0.7”means 2/3 step.
● To cancel the flash

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.

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 the subject.

● Aim the subject at the center of
the viewfinder and press <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
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.
● 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.
● Multi flash mode cannot be set in high-speed sync mode.
● Over-temperature protection may be activated after 15
consecutive high-speed sync flashes.
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.
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.

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 <MODE> button so
1that < > is 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.
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.
Number of Flashes / Flash Frequency = Shutter Speed
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
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 <ETTL>.
● 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 V860IIIC attach to the camera is called the transmitter
unit, and a V860IIIC that is wirelessly controlled is called the
receiver unit.
● You can also wirelessly control the V860IIIC 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.
