Wireless Flash Shooting
The Orlit ST-RT makes it easy to shoot using advanced
wireless multiple flash lighting. Any flash, speedlight or
monolight compatible with the Canon RT radio system
can be controlled with this transmitter, the same way as
normal E-TTL II / E-TTL autoflash exposure.
The system is designed so that the settings of the trans-
mitter attached to the camera (master) are automatically
reflected on the Speedlite that is wirelessly controlled
(slave). Therefore, you do not need to adjust the slave
unit while shooting.
The basic relative positions and operating range are as
shown in the figure. You can then perform wireless E-TTL
II/E-TTL autoflash shooting just by setting the master unit
to < ETTL >.

Autoflash Shooting Using One Slave Unit
You can divide the slave units into two or three groups
and perform E-TTLII/E-TTL auto flash shooting while
changing the flash ratio (factor). In addition, you can
set and shoot with a different flash mode for each firing
group, for up to 5 groups.
