4712 - Overview

Never Miss a Shot Again
The Westcott 4712 FJ400 is the first portable 400Ws AC/DC strobe with under a second recycle speed at full power that offers an impressive 480+ full-power flashes per charge. The lightweight FJ400 offers unrivaled performance with the most accurate color temperature throughout its entire 9-stop output range.

TTL, High Speed Sync, Freeze Sync, and More
With an intuitive menu system and LCD color display, the FJ400 features Manual and TTL Flash Modes, High Speed Sync (HSS) up to 1/8000s, Freeze Sync up to 1/19000s, Continuous Capture up to 20 fps, Mask Function, Delay Function, Automatic Memory Recall, Rear Curtain Sync, Canon RT flash compatibility, group and channel assignment, Group Exposure Compensation, and much more. This strobe is firmware upgradeable via the included USB-C cable.

Say Goodbye to Brand-Specific Triggers
Maximize the FJ400's full potential by pairing it with the powerful FJ-Xm Universal Wireless Trigger. The FJ-X2m offers revolutionary compatibility with many Canon, Nikon, Sony (with adapter), Fuji, Panasonic Lumix, and Olympus cameras (see FJ-X2m compatibility chart). With a large display and user-friendly menu, controlling TTL and HSS has never been easier.

Unrivaled Battery Performance
The removable lithium polymer battery provides both DC power for on-location freedom and AC trickle-charge performance when the state of charge is above 25%.

Consistent Color Temperature at Every Power Level
The FJ400 maintains a color temperature stability of 5500K (±150K) throughout its entire 9-stop output range, with flash increments of either 0.1 or 1.0 stops. It features a 20W 5600K LED modeling lamp with auto-adjust and independent output control.
