Version: v 2.0.0 | Date: 08/07/2025
This manual provides comprehensive instructions for the Westcott FJ80 II Series Touchscreen Speedlight, covering its features, operation, and specifications.
Introduction
Thank you for purchasing the Westcott FJ80 II Touchscreen Speedlight. The FJ80 II is a valuable addition to the FJ Series Wireless product line, which includes the FJ400 Strobe, FJ200 Strobe, FJ80 Speedlight, FJ Wireless Triggers, and FJ-XR Wireless Receiver (all sold separately). The original FJ80 was recognized as the industry's first round-head speedlight and transceiver with multi-brand compatibility and touchscreen controls. The FJ80 II represents the next generation, offering enhanced performance, improved wireless connectivity, and a superior user experience.
The FJ80 II delivers a unique lighting experience. Its round head produces a natural light output, reminiscent of sunlight, creating appealing catchlights in subjects' eyes and evenly illuminating cylindrical modifiers from center to edge. Its compact, lightweight, and performance-driven design makes it ideal for both on-camera and off-camera photography.
The FJ80 II also functions as a transceiver, enabling wireless communication with compatible FJ devices. It can receive wireless communications from the FJ80 II, FJ80, FJ-X Triggers, and Canon RT devices, allowing for flexible placement in tight spaces or for achieving desired lighting effects at various heights.
Westcott HQ is located in Maumee, OH. The support team is available Monday-Friday, 9 am-5 pm ET, to answer questions. Additionally, a community of Westcott users shares tips and tricks via the Westcott Lighting Community on Facebook.
We hope you enjoy using your new lighting tool and are excited to see what you create.
Thank you for your business.

Important things to know before starting...
Reviewing Firmware Files
Firmware updates are available on the Westcott Firmware Update page: https://www.fjwestcott.com/firmware. These updates often enhance performance, modify menu options, and improve the user interface of FJ Wireless products. It is crucial to review all documentation included with each firmware download to ensure all necessary preparation steps are completed before installation.
TTL ±3 Flash Exposure Compensation
The ±3 TTL Flash Exposure Compensation (FEC) applied via FJ Wireless Triggers or a host FJ80 Speedlight (when used as a transmitter) is independent of the FEC displayed on FJ Wireless lights (when used as a client). A change in FEC ±3 on FJ Wireless Triggers or a host FJ80 Speedlight will adjust the light output in TTL mode. However, a client FJ80's touchscreen will not visually reflect these FEC changes made on the trigger or host speedlight. The FJ80 Speedlight's FEC can be further adjusted by ±3 directly on the client light.
Canon Continuous Mode
When using Canon Continuous Mode with FJ Wireless Triggers and the FJ80 II Speedlight, two overlapping squares will appear on the display. In this mode, the FJ Wireless System (including the original FJ80 and FJ-X2m Trigger) defaults to Manual Mode, disabling TTL and HSS functionality. To re-enable these functions, exit Continuous Mode on your Canon camera. Note that FJ80 II and FJ-X3 devices with current firmware have removed these Manual Mode limitations.

Enabling 'HSS (High-speed Sync)'
High-speed Sync is ideal for mixing ambient light and flash when proper exposure with a shallow depth of field/wide aperture requires a flash sync speed above the camera's maximum normal sync speed (typically 1/200s, 1/250s, or 1/320s). HSS allows compatible cameras to achieve flash sync speeds up to 1/8000s.
- Press the Sync Selection button repeatedly until an H with a lightning bolt [⚡] appears in the white square at the top of the screen.
NOTE: HSS requires an FJ-X Transmitter or FJ80 Series Speedlight.
Enabling Freeze Sync
Freeze Sync is ideal for freezing fast-moving objects lit by the speedlight. [Available in Manual Mode Only.]
- Press the physical Home button [?], then tap the Settings menu.
- Locate the Freeze Setting and tap the OFF button until ON appears.

FJ80 II Battery: Performance and Care
FJ80 II Battery Performance
The FJ80 II Lithium-Polymer Battery (11.1V 17.76Wh, 1600mAh) is capable of 500+ full-power flashes with the modeling lamp disabled and screen brightness set to Minimum Brightness (1).
FJ80 II Charging & Life Expectancy
The average charge time is ~2 hours from complete discharge. The FJ80 Lithium-Polymer Battery (11.1V 17.76Wh, 1600mAh) will achieve at least 300 full charge cycles (@80% after 300). Continued usage beyond the expected charge cycles will result in diminished performance and the ability to hold a charge. Avoid charging and using the battery outside of the stated operating temperatures (14~122°F / -10°~50°C) as it will affect the overall performance of the battery and speedlight. Preserve the battery's longevity by storing at roughly ~40% capacity at room temperature in a dry environment and recharge to this capacity at least once every three months when not being used.
