The ST-E10 speedlite transmitter draws its power supply from your camera, making it smaller and lighter in weight compared to battery powered transmitters. ¹
The ST-E10 does not have a LCD screen, however all menu functions can be set through the cameras menu. You can adjust the settings of multiple flash units through the camera, or with your smartphone through the Canon Camera Connect app.
The ST-E10 speedlite transmitter takes advantage of radio transmission, making it less susceptible to interference from obstacles at up to 30m away.
