Alongside the 5D Mark III Canon has also introduced a range of accessories, most notably a new wireless flash system that's based on radio, as opposed to infrared communication. Spearheaded by the weathersealed Speedlite 600EX-RT and the WT-E3-RT wireless transmitter, the switch to radio control greatly increases the system's operational range to 30m, removes the requirement for unobstructed line-of-sight communication between Speedlites and the controller, and increases the number of units that can be used to 15 flashes in 5 groups. There's also a hot-shoe-mountable GPS unit, the GP-E2, and a WFT-E7 Wi-Fi transmitter.
