Wirelessly activating 15 Speedlites via radio transmission enables an endless amount of imagination when it comes to off-camera flash photography. The torque of the wheel-type dial was reduced, making it easier to turn. Together with the dot-matrix LCD display, the ST-E3-RT (Ver. 3) has an intuitive user interface.
These features are made available in the Speedlite Transmitter ST-E3-RT (Ver. 3)* in order to increase the Speedlite EL-1’s capabilities.
Wireless Speedlite Control for Endless Possibilities
You are able to wirelessly trigger up to 16 compatible cameras at once in order to capture the same subject from several angles at the same time.
