Bring all of your Canon TTL flashes into the Nissin Air System with 2.4 GHz radio transmission by mounting them to the Air R Receiver . Using an Air 1 Commander for the Canon E-TTL / E-TTL II system and the Air R Receiver, photographers can now set up and control numerous flashes in an off-camera setup at distances up to 98'. The receivers add wireless slave TTL functionality with support for high-speed sync up to 1/8000 second, manual power control, and manual zoom, with the ability to select between eight channels and organize three groups.
Connecting to a TTL flash is simple as the receiver has a hot shoe on the top for communication. For strobes and manual flashes, the Air R also has a PC sync terminal for basic connections. Mounting the receiver is simple as well with a cold foot on the bottom with a 1/4"-20 thread for stands. There is also a flip-out stand for placing directly on a flat surface. Additionally, it runs on two AAA batteries.
