Portrait photography

It provides greater power and flexibility than a conventional speedlight while remaining small enough for a highly portable lighting kit.
More Than 700 Full-Power Flashes
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.

Important controls are clearly displayed and easy to reach, including:
-
Flash output

-
Zoom position

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.
Reliable FJ Wireless Communication

-
31 wireless channels
-
16 controllable groups
-
Colour-coded LED group indicators

Wireless range up to 100 metres

Automatic and Manual 24–200mm Zoom
The FJ100 features a built-in 24–200mm 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.
Fast Recycling for Demanding Assignments
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.

Weddings
-
Events
-
Sports
-
Dance
-
Rapid portrait sequences

Fast-changing expressions

Moving subjects

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 Mode
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.
Compact Octa 15 Softbox Included

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.
Control Spill with the Egg Crate Grid

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.

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.

Assess shadows

Improve visibility in darker locations
The lamp also features an automatic adjustment function for a more efficient workflow.
