Expand your wireless flash and camera setup with this FA-WRR1 Wireless Radio Receiver from Sony. Featuring a Multi Interface Shoe on the top, this receiver will directly support most Sony-compatible flash units and will even work in manual mode with flashes that use the Auto-lock Accessory Terminal along with an adapter. For full functionality a flash with the Multi Interface Shoe is required, enabling TTL and High-Speed Sync support as well as all remote control functions via the FA-WRC1M Wireless Radio Controller. In order to ensure reliable performance, the system uses a 2.4 GHz radio signal with a range of up to 98.4'. Also, it can operate on one of 14 channels and with up to 5 groups.
In addition to a flash connection, the receiver offers a standard PC sync terminal for connecting to alternative strobes and lights. There is also a Multi Terminal connection for remote triggering of an a7 II, a7R II, or a7S II camera with the use of the separately available VMC-MM1 Multi Terminal. For mounting the flash setup to a stand, the receiver features a cold foot on the base with a 1/4"-20 thread. Additionally, it is dust and moisture resistant for operating in less-than-ideal environments.
