To achieve a professional, and perfect wireless Speedlite setup that requires one or more off-camera flashes, the Canon ST-E10 Speedlite Transmitter is the answer.

The ST-E10 Speedlite Transmitter from Canon is approx. 30% smaller and approx. 50% lighter than the ST-E3-RT II, which is ideal for photographers wanting to carry light – this is all thanks to a transmitter maintains a digital connection to the camera through the shoe, meaning that it doesn’t require batteries; and with quick access to the menu, you’ll easily be able to control and change the 5 independent groups across 15 Speedlites.
