Canon Speedlite Transmitter STE10 4944C001

For wireless Speedlite setups requiring one or more off-camera flashes, the Speedlite Transmitter ST-E10 delivers a transmitter compatible with EOS cameras that include the multi-function shoe. Since this transmitter maintains a digital connection to the camera through the shoe, it does not require batteries, making the design approximately 30% sma... moreller and approximately 50% lighter (than the ST-E3-RT II).Controlling and changing the 5 independent groups across 15 Speedlites is as easy as pressing the menu button located on the transmitter and adjusting the settings from the vari-angle touchscreen on the back of the camera, or with the flash setting screen when using the Canon Camera Connect
