The Canon Speedlite Transmitter ST-E3-RT is a weatherproof radio-frequency flash trigger for reliable off-camera flash control. With the ST-E3-RT, photographers can control compatible Canon Speedlite flashguns - such as the new 600EX-RT - over distances up to 30m, even without direct line of sight. Additionally, the transmitter can also be used for camera triggering - any EOS camera fitted with a Canon ST-E3-RT can be triggered from a second unit or from a compatible Speedlite flashgun. Part of the E-TTL II flash system, the Canon Speedlite Transmitter ST-E3-RT features an easy to read back-lit LCD control screen and is powered by two AA/LR6 batteries.
