and flashes manufactured after 2012 incorporating the
Canon RT wireless radio system.
• The Orlit ST-RT is compatible with the Canon RT wire-
less radio system.
Introduction
The Orlit ST-RT Wireless RT Transmitter is designed espe-
cially for use on CANON cameras and adds 980ft/300m
of remote freedom, without a speedlight, to provide full
TTL, Remote Manual, and HSS, in 5 individual groups.
The wireless radio protocol is based on the popular
Canon RT radio system employed in the Canon 600EX-RT
speedlite. Using a Orlit ST-RT on the camera’s hot shoe,
a Canon photographer can easily adjust the exposure
for any Orlit Rovelight RT Family Monolights and Orlit
RT600C Speedlites. The transmitter is water and dust
resistant equal to the Canon EOS-1D series cameras.
Before using this transmitter, please read this instruction
manual and familiarize yourself with the manuals of your
camera and flashes you are controlling.

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 >.
Positioning and Operation Range (Example of wireless
flash shooting)
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.
