FJ100 Touchscreen Strobe
FJ Mini AC/DC rechargeable battery
FJ-T1 S Wireless Touchscreen Trigger for Sony
Octa 15 Softbox
50 Egg Crate Grid
Compact light stand
Lite Traveler Backpack
Dedicated protective cases and accessories
Each component packs neatly into the supplied backpack, creating a practical lighting system that can be transported between studios, venues and outdoor locations.
The included FJ-T1 S Wireless Touchscreen Trigger is designed specifically for compatible Sony cameras.

Use the bright touchscreen to adjust:
Flash power
TTL settings
Wireless groups
Channels
Sync modes
Creative flash functions
This allows you to make important lighting changes without walking away from the camera or interrupting the shoot.

Its combination of portability and professional output makes it suitable for:
Wedding photography
Portrait photography
Commercial assignments
Fashion shoots
Corporate headshots
Event photography
Product photography
Studio sessions
Location work
It provides greater power and flexibility than a conventional speedlight while remaining small enough for a highly portable lighting kit.
The included 3200mAh FJ Mini AC/DC Battery can deliver more than 700 full-power flashes per charge.
This exceptional battery performance makes the FJ100 suitable for long weddings, events and extended portrait sessions where frequent battery changes could interrupt the workflow.
When more runtime is required, the battery can be charged or powered through USB-C. The same interchangeable battery also powers compatible FJ100 Speedlights, helping reduce the number of different batteries and chargers required in your equipment bag.
The FJ100 features a bright, full-colour LCD touchscreen based around the familiar Westcott FJ Wireless interface.
Important controls are clearly displayed and easy to reach, including:
Flash output
TTL exposure
Wireless group settings
Zoom position
Creative modes
Modelling lamp controls
Built-in help guides provide additional on-screen support, making the system approachable for photographers learning off-camera flash while remaining fast enough for experienced professionals.
The integrated 2.4GHz FJ Wireless system provides dependable communication between the strobe and the included Sony trigger.
Wireless features include:
31 wireless channels
16 controllable groups
Colour-coded LED group indicators
Wireless range up to 100 metres
Remote flash power adjustment
FJ Wireless system integration
This allows you to begin with a single light and expand into a more advanced multi-light setup as your photography develops.
The FJ100 features a built-in 24200mm zoom head that helps control the width and concentration of the flash beam.
The zoom can automatically follow the focal length of your lens or be adjusted manually to suit the lighting setup.
Use a wider zoom position to spread the light across a larger area, or select a longer setting to create a narrower and more concentrated beam.
Recycle times range from just 0.01 to 1.6 seconds, allowing the FJ100 to keep pace with fast-moving shoots.
Continuous flash capture at up to 60 frames per second may also be possible with compatible cameras and settings.
This makes the strobe well suited to photographing:
Weddings
Events
Sports
Dance
Rapid portrait sequences
Fast-changing expressions
Moving subjects
The FJ100 provides a comprehensive range of flash functions for both automatic exposure and precise creative control.
Available modes include:
TTL automatic flash
Manual flash control
High-Speed Sync up to 1/8000 second
Freeze Sync
Front Curtain Sync
Rear Curtain Sync
Stroboscopic Mode
These options allow you to balance flash with daylight, work with wide apertures outdoors, freeze fast movement or create expressive motion effects.
With flash durations as short as 1/40,400 second at t0.5, the FJ100 can freeze extremely rapid movement with impressive clarity.
It is well suited to:
Sports photography
Dance photography
Water splash images
Powder and liquid effects
Fast-moving products
Action portraits
Creative studio photography
The FJ100 maintains a consistent colour temperature of 6000K 200K throughout its full nine-stop output range.
Flash power can be adjusted between 0.78Ws and 100Ws in either 0.1-stop or full-stop increments.
This combination of precise adjustment and dependable colour helps produce repeatable results while reducing the need for extensive correction during post-production.
Creative Mask is an exclusive function within the Westcott FJ Wireless System.
It allows photographers to create up to six different lighting combinations without repositioning the lights or subject.
This can be particularly useful for:
School photography
Sports teams
Volume photography
Composite portraits
Commercial productions
Background replacement workflows
By producing several lighting variations quickly, Creative Mask can reduce production and editing time.
The supplied Octa 15 Softbox transforms the direct flash output into softer and more flattering illumination.
Its compact quick-open design sets up in seconds, making it ideal for photographers who regularly move between locations.
The softbox includes:
Integrated front diffusion
Quick-opening construction
Compact travel design
50 Egg Crate Grid
Dedicated travel case
It is particularly well suited to portraits, headshots, product photography and interview lighting.
The included 50 egg crate grid attaches to the front of the Octa 15 Softbox and narrows the spread of light.
This helps:
Reduce unwanted spill
Keep light away from backgrounds
Increase subject separation
Improve contrast
Direct light more precisely
It provides greater control without removing the soft and flattering quality created by the Octa softbox.
The supplied compact stand extends to approximately 7 feet, allowing the FJ100 and Octa 15 Softbox to be positioned at an effective height for portraits and location work.
Its portable design packs down for travel and fits neatly alongside the rest of the equipment in the backpack.
The strobe mounts securely using its removable tilter bracket and standard 5/8-inch receiver.
The FJ100 includes a 2W LED modelling lamp with a colour temperature of 5500K 200K.
Its independently adjustable brightness helps you:
Preview the direction of light
Assess shadows
Position the subject
Aim the softbox
Improve visibility in darker locations
The lamp also features an automatic adjustment function for a more efficient workflow.
The FJ100 uses intelligent multi-stage heat monitoring to support dependable performance during demanding assignments.
It can produce up to 100 consecutive full-power flashes, helping you work confidently through weddings, events and high-volume portrait sessions.
Additional protection features include automatic power management, heat monitoring and automatic energy dumping.
The included Lite Traveler Backpack provides organised storage for the complete lighting kit.
Features include:
Large central equipment compartment
Removable padded dividers
Multiple zipped accessory pockets
Three padded laptop and tablet sleeves
Water bottle pocket
Tripod or stand holder
Adjustable retention straps
Padded shoulder straps
The backpack keeps the lighting equipment protected and organised while remaining comfortable to carry between locations.

As your requirements grow, additional lights can be added to create:
Two-light portrait setups
Three-point lighting
Background lighting
Rim and separation lighting
Multi-light studio arrangements
High-volume photography systems
