Wireless Flash System. Sony’s first venture into wireless flash, this system offers support for up to fifteen compatible Sony HVL flash units in five groups with full TTL/manual adjustments made via the on-camera Commander unit. By using a 2.4 GHz RF radio signal, you have a working range of up to 98 feet without the need for a line of sight. Each Receiver unit also features a PC-sync input for manually triggering non-Sony flashes and strobes.

Commander/Receiver Kit. This kit includes one FA-WRC1M Commander and one FA-WRR1 Receiver. This combo will allow you to wirelessly trigger a single off-camera flash unit. If you need support for multiple off-camera flashes, you’ll want to rent a Sony FA-WRR1 Wireless Radio Receiver for each additional flash.

Camera Compatibility. This system only supports the Sony Alpha a7S II, a9 II, a9, a7 III, a7R IV, a7R III, a6400, and a6500 cameras with the latest firmware version. If you try to use this system with any other camera model, you’ll be disappointed. Sorry!

Flash Compatibility. This system only supports the Sony HVL-F60M, HVL-F43M, and HVL-F32M flashes mounted via hot shoe (manual triggering via PC sync is compatible with any flash/strobe with PC input) into the FA-WRR1 receiver. Also supported are the newer HVL-F60RM and HVL-F45RM with built-in receivers. These work directly with the FA-WRC1M commander. If you try to use this system with any other Sony flash model, you’ll be disappointed. Sorry!

Power. Sony Alpha Wireless Radio Commander / Receiver Kit uses four AA batteries (not included).
