Product Information
Canon Speedlite Transmitter ST-E3-RT (Ver 3)
Please Note: ST-E3-RT (Ver.3) is NOT compatible with the Canon Speedlite Release Cable SR-N3.
Creative lighting and sophisticated remote flash photography is made easy with the Speedlite Transmitter ST-E3-RT (Ver.3): fire multiple flashes at once, and control settings from a distance. Multiple cameras can be triggered from a distance for synchronised shooting*.

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 SPEEDLITE TRANSMITTER ST-E3-RT (Ver.3). E-TTL II flash metering makes exposure control easy.
Remote Camera Control
Trigger an EOS camera3 fitted with a Speedlite Transmitter from a second unit or from a compatible Speedlite flashgun, such as the Speedlite 600EX II-RT. Up to 15 cameras can be triggered at once, for synchronised shooting.
