Canon Speedlite Transmitter ST-E3-RT
Canon Speedlite Transmitter ST-E3-RT is a Canon wireless flash trigger for E-TTL radio control. It sits on the camera hot shoe and lets you fire and adjust compatible Speedlite flashes without line-of-sight, which is more reliable than optical wireless in bright or obstructed environments. The unit is compact, light and straightforward to use, with Canon’s familiar control layout and a clear LCD for setting groups and power levels. It is aimed at photographers already working with Canon’s RT radio system, especially wedding, event and studio shooters who want fast remote flash control from the camera position. As a transmitter rather than a flash, it does not provide any light output itself. It is typically used with Canon EOS bodies that support E-TTL and radio flash communication. When buying used, check the hot-shoe foot for wear, corrosion or bent contacts, confirm the battery compartment is clean, and make sure buttons, wheel and display respond correctly. Also verify that it pairs and triggers reliably with the flashes you intend to use.
