Canon ST-E3-RT Version 3 Speedlite Transmitter
Shooting with advanced remote flash control is easy with the Canon ST-E3-RT Version 3 Speedlite Transmitter: use multiple flash units simultaneously and control settings remotely. Remotely control multiple cameras for simultaneous shooting.
Control compatible Canon Speedlite flash units to distances of up to 30 metres. 2.4GHz radio frequency for reliable control when shooting outdoors and around corners - direct line of sight not required.
Create complex exposure settings to trigger up to 15 Speedlite flash units via a single, camera-mounted Speedlite Transmitter ST-E3-RT (Version 3). E-TTL II flash metering makes it easy to control exposure.
Control your EOS camera equipped with a Speedlite Transmitter from a second camera or via a compatible Speedlite flash, such as the Speedlite 600EX II-RT. You can control up to 15 cameras simultaneously for synchronised shooting.
The Speedlite Transmitter ST-E3-RT (Version 3) is dust- and moisture-resistant, just like professional EOS cameras and L-series lenses. The transmitter features an easy-to-read backlit LCD control screen and is powered by two AA/LR6 batteries.
The Speedlite Transmitter ST-E3-RT (Version 3) supports wireless second-curtain synchronisation for the EL-1/EL-5 when operated remotely, plus subtle flash exposures of up to 1/8192 and flash exposure memory.
