Compact Power for Location Work
The FJ100 is built for photographers who want serious flash performance without carrying a larger strobe. Its compact design makes it easy to pack, mount, or handhold, while 100Ws of output provides plenty of power for portraits, weddings, events, and creative location lighting.
Industry-Leading Battery Performance
The included 3200mAh FJ Mini AC/DC Battery delivers more than 700 full-power flashes per charge, helping you work for longer with fewer battery swaps. USB-C charging and power support add extra flexibility, and the same battery can also be used with the FJ100 Speedlight, helping reduce the number of batteries and chargers you need to carry.
Fast and Intuitive Touchscreen Control
The bright colour touchscreen uses Westcott's familiar FJ Wireless interface, making it quick to adjust power, wireless groups, TTL settings, and creative modes. Colour-coded group indicators help keep multi-light setups organised, while built-in help guides provide useful support directly on the screen.
Professional Flash Performance
With recycle times as fast as 0.01 seconds, flash durations down to 1/40,400 sec, and continuous capture up to 60fps on compatible cameras, the FJ100 is designed to keep pace with demanding shoots. High-Speed Sync up to 1/8000 sec, Freeze Sync, Front and Rear Curtain Sync, and TTL provide plenty of flexibility for balancing flash with ambient light or freezing fast action.
Shape the Light Your Way
The built-in zoom can automatically match your lens or be manually adjusted from 24mm to 200mm to control beam spread. Native Twist Lock and umbrella mounts provide quick modifier compatibility, while the optional Westcott S-Bracket 2 opens up access to larger Bowens-mount softboxes and other modifiers.
Creative Mask and Stroboscopic Modes
Creative Mask allows multiple lighting combinations to be captured from the same setup without repositioning your lights. By choosing which strobes fire across a sequence of frames, you can create up to six different lighting looks quickly, making it especially useful for sports, school portraits, and high-volume photography. Stroboscopic Mode can also record multiple stages of movement within a single exposure for more creative effects.
Reliable FJ Wireless Integration
The FJ100 works seamlessly with compatible FJ Wireless triggers, speedlights, strobes, and receivers. It supports 16 groups, 31 channels, and wireless operation at distances up to 100 metres, making it easy to build and expand a multi-light setup over time.
Built to Keep Shooting
Intelligent heat protection allows the FJ100 to handle up to 100 consecutive full-power flashes, helping it stay reliable during demanding sessions. A built-in 2W LED modelling lamp provides adjustable continuous illumination for previewing your lighting, while firmware updates are supported through the USB-C port.

TFC's Verdict
The FJ100 is a very appealing option for photographers who want to keep their lighting kit small without sacrificing serious performance.
