Canon ST-E10 Speedlite Transmitter

The technical details behind this transmitter
The ST-E10 Speedlite transmitter draws its power supply from your camera, making it smaller and lighter in weight compared to battery-powered transmitters. The ST-E10 does not have an LCD screen, however, all menu functions can be done through the camera's menu system. You can adjust the settings of multiple flash units through the camera, or connect your smartphone with the Canon Camera Connect App. The ST-E10 Speedlite transmitter takes advantage of radio transmission, making it less susceptible to interference from obstacles up to 30m away.
