SPEEDLITE FLASHES

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
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.

– 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.
The Canon EX-series Speedlite flashes have made multiple-flash photography simple,
wireless and automatic. Using the Speedlite 600EX-RT, 580EX II, Macro Speedlite
MR-14EX, Macro Twin Lite MT-24EX, 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. The EOS 7D, EOS 60D,
EOS Rebel T5i and EOS Rebel T3i 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 take wireless control to the next level, using two-way radio
signals in addition to traditional wireless.

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 the EOS-1D X and the EOS 5D Mark III
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,
Speedlite 600EX-RT and the Speedlite Transmitter
ST-E3-RT are indispensible, eminently adaptable
tools for advanced, professional flash photography.

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.
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. The EOS 7D,
EOS 60D and EOS Rebel T3i cameras, with their
Integrated Speedlite Transmitters, can control
and trigger external Speedlites wirelessly
through their built-in pop up flash. The EOS 60D
camera can wirelessly control the ratio between
A and B groups, along with the built-in unit’s
own output, while the EOS 7D camera can
control A, B, and C groups. Both cameras also
feature 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 most other Speedlite flash features,
such as FE Lock, FP Flash, Flash Exposure
Bracketing/Compensation, and Stroboscopic
Flash. Finally, for macro shooting, the Macro Ring
Lite MR-14EX and Macro Twin Lite MT-24EX can
be used as master units as well.
