The 2.4 GHz system is compatible with Canon cameras and flashes that support E-TTL/E-TTL II for automatic exposure and metering with a wireless range of 100 meters. It can be set to one of 32 channels to limit interference with other nearby systems. Up to five groups can be controlled at a time, or the unit can be set to flash ratio mode for three groups with variable output relative to each other. The flash mounts to the transmitter's top hotshoe, or a studio strobe can be connected via the PC sync terminal on the receiver or the PC sync terminal on the transmitter. It runs on two AA batteries and has a micro-USB port.
