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.
Turn the Select Dial to
3choose a desired flash
output.
● After you finish the setting,
press Set Button and all the
settings will be displayed.
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.
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.
Calculating the 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.
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.
● 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.
● Stroboscopic flash can be used with“buLb”.
● A flash output of 1/1 and 1/2 cannot be set for stroboscopic
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.

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.
Turn the Select Dial to
3choose a desired flash
output.
● After you finish the setting,
press Set Button and all the
settings will be displayed.
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.
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.
Calculating the 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.
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.
● 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.
● Stroboscopic flash can be used with“buLb”.
● A flash output of 1/1 and 1/2 cannot be set for stroboscopic
flash.

Wireless Flash Shooting: Radio (2.4G) Transmission
Using a flash (master/slave) with a radio transmission wireless
shooting function make it easy to shoot with advanced wireless
multiple flash lighting, in the same way as TTL autoflash shooting.
The basic relative position and operation range are as shown in the
picture. You can then perform wireless TTL autoflash shooting just
by setting the master unit to <TTL>.
● You can also wirelessly control the V1F set as the slave unit
with the transmitter X1T-F or XProF (sold separately). For
details on setting the master unit functions, see the
transmitter’s instructions.
● The V1F attach to the camera is called the master unit, and
a V1F that is wirelessly controlled is called the slave unit.

Using Automatic Wireless Flash with Multiple Slave Units
When stronger flash output or
more convenient lighting operation
is needed, increase the number of
slave units and set it as a single
slave unit.
To add slave units, use the same
steps as setting “automatic
wireless flash with a single slave
unit”. Any flash group can be set
(A/B/C/D/E).
When the number of slave units is
increased and the master 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.
● If the slave unit’s auto power off function is workable, press the master
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 slave auto power off is changeable. (C.Fn-Sv STBY
Page 52)
Using Fully Automatic Wireless Flash
The FEC and other settings that set on the master unit will also be
appeared on the slave unit automatically. The slave unit does not
need any operation. Use the following settings to make wireless
flashes according to the same methods with normal flash shooting.
● Flash Exposure Compensation ( Page 39)
About Master Unit
Use two or more master units. By preparing several cameras that
with master units flash attached, cameras can be changed in
shooting while keeping the same lighting source (slave unit).
