Canon ST-E3-RT V2 Wireless Speedlite Transmitter 

 

Fire compatible Speedlite flashguns over distances of up to 30m. Radio-frequency control provides reliable operation even when direct line of sight is not possible. Additional features for the Speedlite EL-1.

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(Ver.2). E-TTL II flash metering makes exposure control easy.

Remote camera control

Trigger an EOS camera fitted with a Speedlite Transmitter ST-E3-RT(Ver.2) 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.
