Free Training & Two Year Warranty
For photographers wanting to use remote Canon Speedlite flashguns with Radio transmission, rather than Optical transmission, the ST-E3-RT is the ideal solution, offering a range of up to 30 metres and control of up to five remote flash groups.
Who is it for?
Professional photographers are more frequently choosing to use portable Speedlite flashguns when working on location because they are lightweight and battery-powered. The Canon Speedlite Transmitter ST-E3-RT acts as a wireless master in the new Canon Radio Wireless flash control system and will therefore find favour among all photographers; both advanced enthusiasts and professionals working with flash and embracing the strobist movement.
The ST-E3-RT will especially be of interest to portrait and commercial shooters, though the 30m range and the ability to trigger a remote camera will also prove interesting to wildlife photographers who are looking to experiment with remote camera setups. Wedding and social photographers will also enjoy the ability to hide flashguns behind subjects or within a scene, without needing a line-of-sight connection between the transmitter and remote Speedlites.
