Wireless Flash Shooting: 2.4G Wireless Transmission
This section explains wireless transmitting/receiving flash shooting.
The V1Pro O attached to the camera is referred as the transmitter unit, while a
V1Pro O that is wirelessly controlled is referred as the receiver unit.
You can also wirelessly control the V1Pro O set as the receiver unit with the
TTL flash trigger XPROII (sold separately). For details on setting the flash
trigger functions, see the its instruction manual.
Using a flash with a radio transmission wireless shooting function make it
easy to shoot with advanced wireless multiple flash shooting, in the same
way as TTL auto flash shooting.
As long as the channel, group, ID, and other relevant wireless settings of the
transmitter and receiver units are set to the same, the settings on the V1Pro
O (transmitter unit) will be automatically applied to the wirelessly controlled
V1Pro O (receiver unit). Therefore, there is no need to operate the receiver unit
during shooting.
1. Multi flash is most effective with a highly reflective subject against a dark
background.
2. Using a tripod and TTL flash trigger XPROII is recommended.
3. A flash output of 1/1 and 1/2 cannot be set for multi flash.
4. Multi flash can also be used with“buLb”mode.
5. Multi flash mode cannot be set in high-speed sync mode.
6. If the number of flashes is displayed as “--”, the ring will continue until the
shutter closes or the battery is exhausted. The number of flashes will be limited
as shown by the following table.

Calculating the Shutter Speed
During multi ash, the shutter remains open until the ring 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 ashes is 10 and the ash frequency is 5Hz,
the shutter speed should be at least 2 seconds.
To avoid overheating and deteriorating the flash head, do not use multi 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 multi flash more than 10 times in
succession, the ring might stop automatically to protect the flash head. If this
happens, allow at least 15 minutes’ rest for the camera 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.
Bounce Flash
330°
-7-120°
1. If the wall or ceiling is too far away, the bounced flash might be too weak and
result in underexposure.
2. 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.
Note：
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 14 to 52mm(43 format) or 28mm to
