Sony-mount wireless trigger for FJ system

The Westcott FJ-X3 S mounts on a Sony hot shoe and controls the FJ Wireless Flash System over 2.4 GHz radio. It offers reliable connectivity up to 985 feet (300 m) in high-interference venues. A removable lithium-ion battery powers the unit for extended shooting sessions. The large display and multi-select control pad enable fast menu navigation.

Photographers needing Sony TTL and high-speed sync

This trigger suits Sony shooters who want TTL, high-speed sync, freeze mode, and front or rear curtain sync with FJ400, FJ200, FJ80 or FJ-XR units. Group and channel assignment plus group exposure compensation are built in. Photographers using non-Sony cameras or brands outside the FJ ecosystem cannot use the proprietary hot shoe or radio protocol.

Bluetooth app expands remote control

The Westcott mobile app connects via Bluetooth to adjust flash settings wirelessly from a smartphone. This adds convenience for solo shooters or lights placed out of reach. No additional cables, receivers or mounting accessories are bundled with the trigger itself.
