10 Cordless flash mode
Wireless remote operation is compatible with the
Canon E-TTL remote system.
The remote system consists of a master flash unit
on the camera and one or more slave flash units.
The slave flash unit(s) are controlled via wireless
technology by the reflector of the master flash unit.
The slave flash unit is assigned to one of three pos-
sible groups (A, B or C). Each group can in turn con-
sists of one or more slave flash units.
The master flash unit can control all of these slave
groups simultaneously and at the same time take
the settings for each slave group into account.
The entire remote system can be operated either
with or mode.
A change to the type of flash mode must be made
on the master.
There are four independent remote channels to use
so that multiple remote systems in the same room
do not interfere with one another. Master and Slave
flash units belonging to the same remote system
must be set to the same remote channel.
The slave flash units must be able to receive the
light from the master flash unit with the integrated
Sensor for cordless remote control .
METTL
Remote flash mode also supports second curtain
synchronisation.
In remote flash mode, the maximum flash range is
not indicated on the flash unit's display panel.
10.1 Remote master mode settings
The slave group A is activated at the factory.
If the master flash unit is deactivated, it only con-
trols the slave units and does not contribute to
exposing the shot.
