Reliable off-camera flash control
Control compatible Canon Speedlite flashguns over distances up to 30m. 2.4GHz
radio frequency triggering operates reliably, even when shooting outdoors and
around corners - direct line of sight not required.
Multiple flash photography
Create intricate multi-flash lighting set ups, triggering up to 15 Speedlite
flashes with a single camera-mounted Speedlite Transmitter ST-E3-RT. E-TTL II
flash metering makes exposure control easy.
Remote camera control
Trigger an EOS camera fitted with a Speedlite Transmitter ST-E3-RT from a
second unit or from a compatible Speedlite flashgun, such as the Speedlite
600EX-RT. Up to 15 cameras can be triggered at once, for synchronised
shooting.
Easy to use design
The Speedlite Transmitter ST-E3-RT is sealed against dust and moisture to the
same degree as professional EOS cameras and L-series lenses. It features an easy
to read back-lit LCD control screen and is powered by two AA/LR6 batteries.
