Product Description

The Sony-compatible Westcott FJ100 S 100Ws Touchscreen Speedlight combines powerful output with a compact design, delivering more power in a smaller body than its predecessor, the FJ80 II. Designed with a dedicated Sony hot shoe, it functions as an on-camera flash, wireless transmitter, or off-camera flash for maximum versatility. A responsive touchscreen interface and color-coded LED group indicators simplify operation and multi-light setups, making it an excellent choice for photographers of all experience levels. The flash features a 24-200mm auto/manual zoom range, while its round head tilts up to 90° and rotates a full 360° for precise light positioning. Ideal for weddings, events, portraits, and location work, the FJ100 S delivers 100Ws of portable lighting power and includes an FJ Mini AC/DC rechargeable battery capable of providing more than 575 full-power flashes per charge.

High Performance for Every Shoot
Delivering an adjustable 9-stop power range from 0.78 to 100Ws in 0.1- or 1-stop increments, the FJ100 S recycles in as little as 0.01 seconds and supports burst shooting up to 60 fps (camera dependent). It offers TTL, Manual, Freeze Sync, High-Speed Sync up to 1/8000 sec, front and rear curtain sync, and stroboscopic flash modes, giving photographers the flexibility to handle everything from fast-paced events to creative lighting setups.

Smooth, Consistent Illumination
A round Omega flash tube produces soft, even light with natural-looking falloff, making it especially well suited for portraits, weddings, and event photography. A built-in 3W LED modeling lamp provides continuous illumination with adjustable brightness and auto-adjust functionality, while consistent color accuracy is maintained throughout the entire power range.

Optimized for Sony & Wireless Control
Equipped with a dedicated Sony-compatible hot shoe, the FJ100 S works seamlessly on compatible cameras while its integrated 2.4 GHz transceiver enables wireless operation as both a transmitter and receiver. Use it on-camera or position it off-camera as part of a wireless lighting setup.

Intuitive Touchscreen Operation
The high-resolution touchscreen offers fast, straightforward access to flash power, zoom settings, wireless controls, and creative shooting modes without navigating complex menus. Wireless communication extends up to 328', supporting up to 16 groups across 31 channels. Color-coded LED group indicators simplify identifying each light, and users can display power levels in either stops or fractional values to match their preferred workflow.

Expandable FJ Wireless System
Designed to grow with your lighting setup, the FJ100 S integrates seamlessly with Westcott's FJ Wireless System. Pair it with an optional FJ Wireless Trigger and the free Westcott StudioLink app to remotely adjust settings, control multiple lights, and access advanced features directly from your smartphone.

USB-C Rechargeable FJ Mini AC/DC Battery
Powered by the included removable 7.4V, 3200mAh, 23.68Wh lithium-ion FJ Mini AC/DC battery, the FJ100 S delivers more than 575 full-power flashes per charge and fully recharges in approximately 2.3 hours. LED indicators display battery status at a glance, while USB-C charging and power support let you continue shooting with minimal interruption. Battery compatibility with the FJ100 strobe simplifies power management across your lighting kit.

Flexible Mounting & Light Shaping
The integrated Twist Lock mount supports a variety of optional light modifiers, including reflectors, snoots, and barndoors. When paired with the separately available Westcott S-Bracket 2, the flash also accepts Bowens-mount softboxes and modifiers weighing up to 1 lb. A built-in shoe mount and the included mini stand with a 1/4"-20 receiver provide flexible mounting options for off-camera use.

Built for Professional Reliability
An intelligent passive cooling system with multi-stage thermal protection allows up to 100 consecutive full-power flashes while helping maintain reliable performance during demanding shoots. IGBT+ technology enhances flash efficiency and camera compatibility, and firmware updates are easily installed through the USB-C data port to keep the flash current with the latest features and improvements.
