DETAILS
The Canon ST-E3-RT Speedlite Transmitter is a wireless transmitter and power control unit designed specifically for the Canon Speedlite 600EX-RT. It supports E-TTL II flash control, manual flash control, stroboscopic/high speed sync (except when used on camera models from 2012 and older), and external flash metering. This transmitter is placed on the hot shoe of your camera where it will fire an off-camera Canon Speedlite 600EX-RT (not included) and allow you to control the flash's settings right from the transmitter. This transmitter is not compatible with Speedlite models prior to the Canon Speedlite 600EX-RT.
