Westcott FJ100 Touchscreen Speedlight Flash – 100Ws

The Most Powerful Compact Speedlight in the Westcott FJ Wireless System

The Westcott FJ100 Touchscreen Speedlight combines 100Ws of portable flash power, professional wireless control, long battery life, and an intuitive color touchscreen in a compact round-head design.

Use the FJ100 directly on your camera as a powerful TTL speedlight and FJ Wireless transmitter, or position it off-camera as part of a complete multi-light system.

With fast recycling, high-speed sync, TTL, Freeze Sync, a 24–200mm zoom range, and more than 575 full-power flashes per charge, the FJ100 is built for weddings, events, portraits, sports, and demanding location photography.

More Power in a Compact Speedlight

The FJ100 delivers up to 100Ws of flash power—giving photographers greater output than a traditional speedlight while maintaining the portability and convenience of an on-camera flash.

Its nine-stop power range can be adjusted from 0.78Ws to 100Ws in either 0.1-stop or full-stop increments.

This flexibility allows you to quickly lower the power for subtle fill light or use the full 100Ws when you need additional output for outdoor portraits, bounce flash, larger groups, or light modifiers.

Bright Full-Color Touchscreen

The FJ100 features a high-resolution 2-inch LED color touchscreen that places your most important controls within easy reach.

Quickly adjust:

• Flash power
• TTL compensation
• Flash zoom
• Wireless groups and channels
• Synchronization modes
• Modeling light output
• Transmitter and client settings
• Creative flash functions

The intuitive Westcott interface makes it easy to change settings without navigating through complicated button combinations or difficult menus.

Color-coded group indicators also make it easier to identify and manage individual lights when working with a multi-light FJ Wireless setup.

Use It On-Camera or Off-Camera

The Westcott FJ100 can serve several roles within your lighting system.

Mount it directly to your camera and use it as:

• An on-camera TTL flash
• A bounce flash
• A fill flash
• An FJ Wireless transmitter
• An on-camera flash and transmitter simultaneously

You can also position the FJ100 off-camera and control it wirelessly from a compatible Westcott FJ trigger or speedlight.

This versatility allows the FJ100 to function as your primary flash, a portable accent light, a reception light, a background light, or part of a larger multi-light system.

Built-In FJ Wireless Transmitter

The FJ100 includes a built-in 2.4 GHz wireless transceiver for the Westcott FJ Wireless System.

When mounted on-camera, the FJ100 can control compatible Westcott FJ speedlights, strobes, and receivers. When positioned off-camera, it can operate as a wireless client controlled by another compatible FJ transmitter.

The wireless system provides:

• Up to 328 feet of operating range
• 31 wireless channels
• Six host groups
• 16 client groups
• Color-coded group identification
• TTL and manual flash control
• High-speed sync
• Remote power adjustment
• Multi-light system control

This makes it easy to begin with a single FJ100 and expand your lighting system as your photography needs grow.

Multi-Brand Camera Compatibility

The Multi-Brand version of the FJ100 is compatible with several popular camera systems, including:

• Canon
• Nikon
• Fujifilm
• Panasonic Lumix
• Olympus
• Sony in manual mode

A dedicated Sony version is also available for photographers who need full compatibility with Sony cameras.

The FJ100 features a durable all-metal hot shoe for a secure and reliable connection to your camera.

Camera features and compatibility can vary by camera manufacturer and model. Contact FlashGear before purchasing if you need help choosing the correct version for your camera.

TTL for Fast-Moving Situations

TTL automatically measures the light passing through your camera lens and adjusts the flash output to help establish an accurate exposure.

This can be especially helpful when photographing:

• Weddings
• Receptions
• Events
• Children
• Moving subjects
• Rapidly changing environments
• Subjects at varying distances

TTL allows you to react quickly when you may not have time to manually meter and adjust your flash before every photograph.

Once you establish the desired exposure, you can continue using TTL or switch to manual power for consistent results from one image to the next.

High-Speed Sync for Outdoor Portraits

High-speed sync allows the FJ100 to operate at shutter speeds up to 1/8000 second with compatible cameras.

This gives you greater control over ambient light when working outdoors.

High-speed sync can help you:

• Use wide apertures in bright conditions
• Create a shallow depth of field
• Darken bright backgrounds
• Reduce ambient exposure
• Photograph with fast shutter speeds
• Balance flash with direct sunlight
• Maintain creative control over your exposure

This makes the FJ100 a powerful option for outdoor portraits, senior photography, weddings, sports, and environmental photography.

Freeze Fast Action

Freeze Sync and IGBT+ technology allow the FJ100 to produce extremely short flash durations.

Flash durations can reach as short as 1/55,600 second at t0.5 in Freeze Mode, helping stop movement with outstanding clarity.

This is particularly useful for:

• Sports photography
• Dance photography
• Fitness portraits
• Hair movement
• Splash photography
• Product photography
• Children and pets
• Other fast-moving subjects

The FJ100 can also support continuous capture rates up to 60 frames per second with compatible cameras and appropriate power settings.

Fast Recycling

The FJ100 offers recycle times ranging from approximately 0.01 to 1.6 seconds.

Fast recycling helps the flash remain responsive during weddings, events, portrait sessions, sports, and other situations where moments happen quickly.

Intelligent multi-stage heat protection allows the FJ100 to produce up to 100 consecutive full-power flashes while monitoring the operating temperature of the unit.

Industry-Leading Battery Performance

The removable Westcott FJ Mini AC/DC Battery provides more than 575 full-power flashes from a single charge.

This allows photographers to work through long portrait sessions, weddings, events, and assignments with fewer battery changes.

The 3200mAh battery can be charged through USB-C, and the FJ100 can also be charged or powered through USB-C while in use.

The same FJ Mini Battery is compatible with the Westcott FJ100 Strobe, allowing photographers who own both products to use interchangeable batteries and reduce the number of chargers and battery types they need to carry.

Round Flash Head for Smooth, Even Light

The FJ100 uses a round Omega flash tube that produces smooth, even illumination with natural-looking light falloff.

Compared with a traditional rectangular speedlight head, the round design can provide more uniform coverage when used directly, bounced, or paired with compatible light modifiers.

The flash head rotates a full 360 degrees horizontally and tilts up to 90 degrees vertically.

This gives you the flexibility to:

• Bounce light from ceilings
• Bounce light from nearby walls
• Feather the flash away from your subject
• Position the head for vertical photographs
• Direct the flash into a modifier
• Create softer and more natural-looking on-camera flash

Automatic and Manual 24–200mm Zoom

The built-in flash zoom can be adjusted from 24mm to 200mm.

When used with compatible cameras, automatic zoom can match the flash beam to the focal length of your lens. You can also manually control the zoom when you want to change the spread or concentration of the light.

A wider zoom setting creates broader coverage, while a longer zoom setting concentrates the light into a narrower beam.

Manual zoom can be especially useful when using the FJ100 off-camera or when you want to intentionally control where the light falls.

Built-In LED Modeling Light

The FJ100 includes a 3W LED modeling lamp inside the flash head.

The modeling light can help you:

• Preview the direction of the light
• Identify shadows
• Position the flash
• Add focusing assistance in darker environments
• Visualize how the light may fall on your subject
• Use the speedlight as a small continuous light when needed

The modeling lamp has a color temperature of approximately 5500K.

Compatible With Westcott Twist Lock Modifiers

The FJ100 is compatible with Westcott Twist Lock modifiers and accessories.

These compact magnetic-style accessories allow you to quickly modify the shape, softness, spread, or color of the light.

Compatible accessories may include:

• Diffusion domes
• Grids
• Gel holders
• Bounce cards
• Snoots
• Reflectors
• Creative modifier kits

The FJ100 can also be paired with the separately available Westcott Quick-Mount S-Bracket 2 for use with Bowens-mount softboxes and other Bowens-style modifiers.

Mount It to a Light Stand

The included speedlight shoe stand features a 1/4-20 threaded receiver, allowing the FJ100 to be mounted to many compatible light stands, brackets, clamps, and support accessories.

This makes it easy to transition from on-camera flash to an off-camera lighting setup.

For larger modifiers, FlashGear recommends using a dedicated speedlight bracket such as the Godox S3 Bracket rather than placing the weight of the modifier directly on the speedlight.

Advanced Creative Flash Functions

The Westcott FJ100 includes several advanced functions for creative and professional photography.

Stroboscopic Mode

Stroboscopic Mode fires the flash multiple times during a single exposure, allowing you to capture several stages of movement in one photograph.

This can be used to create dynamic images of dancers, athletes, performers, products, and other moving subjects.

Front-Curtain Sync

Front-curtain synchronization fires the flash near the beginning of the exposure and is the standard setting for most flash photography.

Rear-Curtain Sync

Rear-curtain synchronization fires the flash near the end of the exposure.

When working with slower shutter speeds, this can create more natural-looking motion trails that appear behind a moving subject.

Creative Mask

When used with a compatible Westcott trigger and the StudioLink app, Creative Mask can produce multiple lighting combinations without requiring you to reposition your subject or lights.

This can be helpful for volume photography, sports composites, background removal, product photography, and creative portrait workflows.

Delay Function

The Delay function allows the photographer to control when the flash fires during the exposure when used with compatible Westcott equipment and the StudioLink app.

Expand Your System With the StudioLink App

When paired with a compatible FJ Wireless trigger, the free Westcott StudioLink app provides additional control from a mobile device.

Depending on the connected equipment, photographers can remotely adjust settings, manage compatible lights, and access advanced functions directly from the app.

Ideal for Weddings and Events

The FJ100 is especially well suited for wedding and event photographers.

Use it on-camera during rapidly changing moments, then use the same flash as a wireless transmitter to control off-camera FJ strobes or speedlights during the reception.

Its combination of 100Ws output, TTL, high-speed sync, fast recycling, long battery life, and wireless control makes it capable of handling:

• Getting-ready photographs
• Wedding ceremonies
• Formal portraits
• Family photographs
• Reception entrances
• First dances
• Toasts
• Open dancing
• Cake cutting
• Sparkler exits
• Corporate events
• Parties and celebrations

Ideal for Portable Multi-Light Systems

The FJ100 can also serve as a compact off-camera flash for:

• Portrait photography
• Senior photography
• Headshots
• School photography
• Sports photography
• Fitness photography
• Product photography
• Real estate photography
• Travel photography
• Location assignments

Carry several FJ100 speedlights to create a lightweight multi-light system, or combine the FJ100 with more powerful FJ strobes when you need additional output.
