Excerpt: Take only what is necessary for radio wireless remote flash and camera control out of the Canon Speedlite 600EX-RT Flash , and what you have left is the Canon Speedlite Transmitter ST-E3-RT. Consuming approximately half of the space of the non-head portion of the 600EX-RT, the ST-E3-RT offers full control of Canon's radio-based wireless system, triggering (or being triggered by) either a flash or a camera.
