The Canon ST-E3-RT Speedlite Transmitter is a wireless transmitter and power control unit designed specifically for the Canon Speedlite 600EX-ET. It supports E-TTL flash control, manual flash control, stroboscopic/high speed sync (except when used on camera models 2012 and older), and external flash metering. This transmitter is placed on the hotshoe of your camera where it will fire the off-camera 600EX-RT (not included) and allow you to control the flash's settings right from the transmitter. Note that this transmitter will NOT work on the 580EX II or earlier flash models.
