Wireless Radio Control
For sophisticated wireless flash setups, the
Speedlite 600EX-RT and the Speedlite
Transmitter ST-E3-RT represent the next
generation in wireless flash systems. In
addition to
traditional
optical
wireless
transmission,
both the
Speedlite
600EX-RT and
the Speedlite Transmitter ST-E3-RT facilitate
radio controlled, two-way wireless
transmission up to 100 feet, among up to five
groups or 15 individual Speedlite flashes.
Communicating on 2.4 GHz frequencies for
radio transmission, radio controlled flash
systems do not have the same directional
limitations of traditional wireless optical
transmitters. Where other wireless systems’
signals can be interrupted with physical
obstacles, radio controlled systems excel. To
avoid interference with other equipment on the
same frequency, 15 transmission channels are
available, selectable manually or
automatically, and radio transmission IDs can
be set to prevent misfiring in the event of
signal interference on the same channel. With
diverse flash metering options, and a number
of flash modes all accessible from the menu
and quick control screens of select EOS
cameras, the Speedlite 600EX-RT and the
Speedlite Transmitter ST-E3-RT make complex
lighting setups simple. With compact, weather
sealed and reliable designs, combined with
improved information panels and controls,
The Canon EX-series Speedlite flashes have made multiple-flash
photography simple, wireless and automatic. Using the Speedlite
600EX-RT, Macro Ring Lite MR-14EX II, or Speedlite Transmitters
ST-E2 or ST-E3-RT as a master unit, wireless signals are
transmitted to numerous Speedlite flashes, creating myriad
possibilities for lighting, no matter the location. Select
EOS cameras have Integrated Speedlite Transmitters, allowing
users to wirelessly control EX-series Speedlite flashes and doing
away with the need for an external master unit. The Speedlite
600EX-RT and the Speedlite Transmitter ST-E3-RT use two-way
radio signals in addition to traditional wireless.
Wireless Flash Photography
Speedlite 600EX-RT and the
Speedlite Transmitter
ST-E3-RT are indispensible,
eminently adaptable tools
for advanced, professional
flash photography.
E-TTL/E-TTL II Wireless
Autoflash Control
Up to three groups (for main, fill and
background) of slave units can be set up for
comprehensive control of flash lighting. The
Speedlite flash slave units can be assigned to
group A, B, or C, with output ratio between
groups A and B adjustable from 8:1 to 1:1 or
1:1 to 1:8. The output of the group C can be
adjusted through flash exposure
compensation. Superb lighting is simple
thanks to the E-TTL/E-TTL II autoflash system
which controls the total flash output to ensure
consistently correct exposure. Select EOS
cameras with Integrated Speedlite
Transmitters can control and trigger external
Group firing mode
Group Firing
1
– Set different flash modes for each group
(A, B, C, D, and E) and perform multiple wireless flash
shooting. Two or more units can be set as the same group.
Linked shooting function – Releases the camera that has the
Speedlite 600EX-RT (or Speedlite Transmitter ST-E3-RT) set
as the master unit and release up to 15 cameras with the
Speedlite or transmitter set as slave units.

1 Group firing mode is supported by the EOS-1D X, EOS 5D Mark III and later camera models. In earlier camera models, all flashes will switch to E-TTL automatically and group control is reduced to 3 groups.
Speedlites wirelessly through their built-in
pop-up flash. The EOS 7D Mark II camera can
control A, B, and C groups and also has a
modeling flash feature for previewing the
output of your external Speedlite flashes,
available by pressing the depth-of-field
button. Even with multiple Speedlite flashes,
the modeling flash fires according to the ratios
you have set. E-TTL/E-TTL II wireless autoflash
also supports other Speedlite flash features
including FE Lock, FP Flash, Flash Exposure
Bracketing/Compensation, and Stroboscopic
Flash. Finally, for macro shooting, the Macro
Ring Lite MR-14EX II and Macro Twin Lite
MT-24EX can be used as master units as well.
