The radio-controlled flash system consists of the FA-WRC1M radio transmitter and the separately available FA-WRR1 radio receiver and is, after software update, compatible with the Alpha 7 series cameras and Sony flash units. Thanks to its flexibility, the system is completely portable. This makes it ideal for wedding photographers, for example, who need to shoot perfect pictures right away, but often work in places where only a whole studio lighting can be lugged. The radio-controlled system has a range of up to 30 meters and supports TTL, manual or group mode. Up to 15 separate flash units can be controlled in up to five groups. The shooting mode or the exposure compensation for the distant flashes can be adjusted individually via the transmitter. The FA-WRC1M features a large, easy-to-read control panel that can confirm communication status for each receiver flash. perfect for photographers who work alone or in a small team. In addition, the system enables the remote triggering of multiple cameras. In total, up to five groups can be controlled. If you choose TTL or manual mode, you have to restrict yourself to three groups. Since the system has a range of up to 30 meters, pictures can be captured from different perspectives at the decisive moment if desired.
