100Ws in a Compact Speedlight
With 100Ws of flash power, the FJ100 S delivers impressive output from a compact on-camera design. The 9-stop power range gives you plenty of control, whether you need a subtle touch of fill or more powerful illumination for portraits, events, and location work.
Built for Sony Cameras
The FJ100 S is purpose-built for Sony photographers, combining full TTL functionality with a durable all-metal hot shoe for a reliable connection between flash and camera. This dedicated design makes it an ideal choice for Sony shooters who want the convenience of automatic TTL exposure alongside the advanced creative controls of the FJ Wireless System.
All-Day Battery Performance
The included 3200mAh FJ Mini AC/DC Battery provides more than 575 full-power flashes per charge, helping you keep shooting through long weddings, events, and portrait sessions. USB-C charging and power support add extra flexibility, while the interchangeable battery is shared with the FJ100 Strobe to simplify your FJ Wireless kit.
Fast, Intuitive Touchscreen Control
A bright 2-inch high-resolution colour touchscreen puts your most important settings within easy reach. The intuitive FJ Wireless interface makes it quick to adjust flash power, zoom, wireless groups, and creative modes without digging through complicated menus.
Round Head for Natural-Looking Light
The round Omega flash tube produces smooth, even illumination with natural-looking falloff. The head can tilt up to 90° and rotate through 360°, giving you plenty of freedom for direct, bounced, or feathered lighting. A built-in 24-200mm zoom can automatically match your lens focal length or be adjusted manually for more precise control over the beam.
On-Camera or Off-Camera
Use the FJ100 S directly on your Sony camera or as a wireless transmitter for other FJ Wireless lights. Off-camera, it functions as a wireless client flash with dependable 2.4GHz communication across 16 groups and 31 channels at distances up to 100 metres. Colour-coded group indicators also make larger multi-light setups easier to organise.
Professional Flash Performance
Recycle times from 0.01 to 1.6 seconds and continuous capture up to 60fps on compatible cameras help the FJ100 S keep pace with fast-moving subjects. Flash durations as short as 1/55,600 sec help freeze action, while intelligent heat protection supports up to 100 consecutive full-power flashes for demanding shoots.
Advanced Creative Control
TTL and Manual modes are joined by High-Speed Sync up to 1/8000 sec, Freeze Sync, Front and Rear Curtain Sync, and Stroboscopic Mode. IGBT+ technology provides precise flash control, while firmware can be updated through the USB-C connection to keep the speedlight current with future improvements.
Flexible Modifier Compatibility
The FJ100 S works directly with Westcott Twist Lock light modifiers for quick and convenient light shaping. For larger setups, the optional Westcott S-Bracket 2 adds compatibility with Bowens-mount softboxes and other modifiers. The flash can also be mounted off-camera using its built-in cold shoe or the included shoe stand with a 1/4"-20 threaded receiver.
