Westcott FJ100 Strobe 2-Light Backpack Kit with FJ-T1 S Wireless Trigger for Sony Cameras
Create a versatile professional lighting setup wherever you shoot with the Westcott FJ100 Strobe 2-Light Backpack Kit for Sony Cameras. This complete portable system combines two compact 100Ws FJ100 Touchscreen Strobes with the dedicated FJ-T1 S Wireless Trigger, two light stands, an Octa 15 Softbox, a Twist Lock Creative Pack and the Lite Traveler Backpack.
Designed specifically for compatible Sony cameras, the kit provides intuitive TTL control, High-Speed Sync, rapid recycling and dependable wireless performance. With two independently controllable strobes, photographers can create polished key-and-fill setups, background lighting, rim lighting and creative colour effects without carrying a bulky studio system.
A Complete Two-Light Kit for Sony Photographers
This ready-to-use kit provides the core equipment required to build a flexible two-light setup for studio and location photography.
Use the two FJ100 Strobes to create:
-
Key and fill lighting
-
Main and rim lighting
-
Subject and background lighting
-
High-key portraits
-
Dramatic low-key images
-
Product photography setups
-
Corporate headshots
-
Wedding and event lighting
-
Creative gel effects
-
Sports and volume photography
Two strobes, two batteries, two stands and multiple light-shaping accessories are included, giving Sony photographers a practical system that can be adapted to different assignments.
Two Ultra-Compact 100Ws Strobes
Each FJ100 delivers 100 Watt-seconds of flash power in a body approximately the size of a soft drinks can.
The compact design makes the strobes easy to transport, while their professional output provides considerably more flexibility than a conventional speedlight.
The two-light configuration allows one strobe to act as the main light while the second can provide:
-
Fill light
-
Hair light
-
Rim lighting
-
Background illumination
-
Coloured accent lighting
-
Additional output through a second modifier
The system is ideal for portraits, weddings, events, fashion, commercial work, product photography and professional location assignments.
Dedicated FJ-T1 S Sony Wireless Trigger
The included FJ-T1 S Wireless Touchscreen Trigger is designed specifically for compatible Sony cameras.
Mounted directly to the camera’s hot shoe, it provides intuitive wireless control over both FJ100 Strobes and other compatible lights within the FJ Wireless System.
Use the touchscreen to adjust:
-
Flash power
-
TTL exposure
-
Wireless groups
-
Channels
-
Sync modes
-
Creative flash functions
Both strobes can be assigned to separate groups, allowing their outputs to be adjusted independently without leaving the camera position.
Build Balanced Two-Light Setups
A two-light system gives photographers significantly more control over contrast, dimension and subject separation.
One FJ100 can be used as the key light while the second provides:
-
Gentle fill to soften shadows
-
Rim light to separate the subject from the background
-
Hair light for portraits
-
Background illumination
-
Cross-lighting for action
-
Coloured accent lighting
-
Additional power for group photographs
Because both strobes are controlled wirelessly, lighting ratios can be adjusted quickly as the scene changes.
More Than 700 Full-Power Flashes Per Battery
Each included 3200mAh FJ Mini AC/DC Battery delivers more than 700 full-power flashes per charge.
With a dedicated battery for each strobe, the kit provides the endurance needed for long weddings, events, portrait sessions and commercial assignments.
When additional runtime is required, the batteries can be charged or powered through USB-C. The same batteries also work with compatible FJ100 Speedlights, helping reduce the number of chargers and battery types required across a larger lighting system.
Bright Full-Colour Touchscreen Controls
Each FJ100 features a bright full-colour LCD touchscreen with the familiar Westcott FJ Wireless interface.
Important settings are clearly displayed and easy to adjust, including:
-
Flash output
-
TTL compensation
-
Wireless groups
-
Wireless channels
-
Zoom position
-
Sync functions
-
Modelling lamp brightness
-
Creative modes
Built-in help guides provide on-screen support, making the system accessible to photographers learning off-camera flash while remaining fast enough for experienced professionals.
Reliable Wireless Control Across 16 Groups
The integrated 2.4GHz FJ Wireless system provides dependable communication at distances of up to 100 metres.
Wireless features include:
-
31 wireless channels
-
16 independently controllable groups
-
Colour-coded LED group indicators
-
Remote power adjustment
-
TTL and Manual control
-
Expandable FJ Wireless compatibility
The two included strobes can be controlled independently, while additional FJ Wireless lights can be added as your lighting requirements grow.
Automatic and Manual 24–200mm Zoom
Each FJ100 includes a built-in 24–200mm zoom head for precise control over the spread of light.
The zoom can automatically match the lens focal length or be adjusted manually according to the desired effect.
Use a wider setting to spread light across a broader area or select a longer zoom position to create a narrower, more concentrated beam.
This is particularly useful when using one strobe as a background light, rim light or tightly controlled accent.
Fast Recycling for Events and Action
Recycle times from just 0.01 to 1.6 seconds help the FJ100 Strobes keep pace with demanding shoots.
Continuous flash capture at up to 60 frames per second may also be possible with compatible Sony cameras and settings.
This rapid performance is particularly useful for:
-
Weddings
-
Events
-
Dance
-
Sports portraits
-
Rapid portrait sequences
-
Moving subjects
-
High-volume photography
-
Commercial production work
Professional TTL and Manual Flash Modes
The FJ100 system provides a broad range of flash modes for both automatic exposure and precise creative control.
Available functions include:
-
Sony TTL automatic flash
-
Manual flash output
-
High-Speed Sync up to 1/8000 second
-
Freeze Sync
-
Front Curtain Sync
-
Rear Curtain Sync
-
Stroboscopic Mode
These options allow photographers to balance flash with bright ambient light, use wider apertures outdoors, freeze movement or create multiple-exposure effects.
Freeze Fast-Moving Subjects
The FJ100 can deliver flash durations as short as 1/40,400 second at t0.5 in Freeze mode.
This makes the strobes well suited to photographing:
-
Water splashes
-
Flying powder
-
Dance
-
Sports action
-
Fast-moving products
-
Creative portrait effects
-
High-speed studio subjects
Using two strobes also allows fast movement to be frozen while maintaining more balanced or dimensional lighting.
Consistent 6000K Colour Output
Each 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.
Consistent output between both strobes helps simplify multi-light setups and reduces the need for extensive colour correction during post-production.
Creative Mask Mode
Creative Mask is an exclusive feature of the Westcott FJ Wireless System.
It allows photographers to capture up to six different lighting combinations without moving the lights or subject.
This can be particularly useful for:
-
School photography
-
Sports teams
-
Volume photography
-
Composite portraits
-
Product photography
-
Background removal
-
Commercial production
Creative Mask can help speed up both the shooting and editing process by producing multiple lighting variations in rapid succession.
Twist Lock Creative Pack Included
The supplied Creative Pack includes 15 stackable modifiers that attach quickly using the FJ100’s Twist Lock mount.
The pack includes:
-
Barndoors
-
Snoot
-
Bounce card
-
Honeycomb grid
-
Dispersion lens
-
Ten rigid colour gels
These accessories can be mixed, matched and stacked to create a wide range of effects.
Use them to:
-
Restrict unwanted spill
-
Create coloured backgrounds
-
Produce a narrow spotlight
-
Add hard-edged highlights
-
Spread the beam
-
Bounce light forwards
-
Create dramatic portrait effects
One strobe can be fitted with the Octa softbox as the main light while the second uses the Creative Pack for background, rim or colour effects.
Octa 15 Softbox Included
The supplied Octa 15 Softbox transforms the direct flash output into softer, smoother and more flattering illumination.
Its compact quick-opening design sets up in seconds, making it ideal for photographers who regularly move between studios and locations.
The softbox features:
-
Integrated front diffusion
-
Quick-open construction
-
Compact folding design
-
Twist Lock compatibility
-
Dedicated travel case
-
Included 50° egg crate grid
It is particularly effective for portraits, headshots, interviews, product photography and wedding detail shots.
50° Egg Crate Grid
The included egg crate grid attaches to the front of the Octa 15 Softbox and narrows the spread of light.
It helps:
-
Reduce unwanted spill
-
Keep light away from backgrounds
-
Improve subject separation
-
Increase contrast
-
Direct illumination more precisely
-
Prevent one light from affecting another area of the setup
This extra control is especially useful when using both FJ100 Strobes together.
Two Compact Light Stands
The kit includes two compact light stands, allowing both strobes to be positioned independently.
The two stands can be used to create:
-
Key and fill lighting
-
Cross-lighting
-
Main and background lighting
-
Main and rim lighting
-
Symmetrical product lighting
-
Two-sided portrait setups
Each stand packs down for transport and fits alongside the rest of the kit within the Lite Traveler Backpack.
Built-In LED Modelling Lamps
Each FJ100 features a 2W LED modelling lamp with a colour temperature of 5500K ±200K.
The independently adjustable modelling lights can help you:
-
Preview the direction of light
-
Position the strobes
-
Assess shadows
-
Aim modifiers
-
Separate the subject from the background
-
Work more comfortably in darker locations
Automatic adjustment functionality further streamlines the lighting workflow.

-
Multi-stage thermal monitoring

Passive cooling

Automatic energy dumping
