Radio Transmission
Note:
The Transmitter attached to the camera is
called the master unit, and a ash that is
wirelessly controlled is called the slave unit.
Wireless Flash Shooting
Using a Transmitter and Canon radio-enabled
Speedlites makes it easy to shoot with
advanced wireless multiple ash lighting, in the
same way as normal E-TTL II/E-TTL auto ash
shooting.
The settings of the Transmitter attached to the
camera (master) are automatically reected on
the ash that is wirelessly controlled (slave).
You do not need to operate the slave unit while
shooting. You can then perform wireless E-TTL
II/ETTL autoash shooting just by setting the
master unit to ETTL mode.
You can choose to perform autoash shooting
using one slave unit only, or perform wireless
multiple ash shooting using two or more(up
to 15) slave units.
