Westcott FJ400 Strobe 2-Light Backpack Kit with FJ-X3S Wireless Trigger for Sony Cameras

The Westcott FJ400 Strobe is the first 400Ws portable AC/DC strobe with a recycle time of less than a second at full power and a remarkable 480+ full-power flashes per charge. Throughout its entire 9-stop output range, the portable FJ400 provides unmatched performance with the most accurate color temperature. The FJ400 offers 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, compatibility with Canon RT flash, group and channel assignment, Group Exposure Compensation, and many other features. It also has an intuitive menu system and LCD color display. The USB-C cable that comes with the strobe can be used to upgrade its firmware.

Support for Dedicated Sony Cameras

The FJ400 strobe offers unmatched capabilities like High-Speed Sync, TTL, and more when used with an FJ-X3 S Wireless Trigger. For Sony cameras, the wireless trigger is built with a special Sony hot shoe mount. For more information, see the compatibility table.

Outstanding Battery Performance

The detachable lithium polymer battery offers both AC trickle-charging functionality when the level of charge is greater than 25 percent and DC power for freedom while operating on location.

Color Temperature Consistency at Every Power Level

With flash increments of either 0.1 or 1.0 stops, the FJ400 maintains a color temperature constancy of 5500K (150K) throughout its entire 9-stop output range. It has a 20W 5600K LED modeling lamp with separate output control and auto-adjustment.

Light Modifier Optimization

The expanded flash tube's ideal light output enables filling light modifiers to have a wider, more uniform spread of light. The Bowens S-Type mounting system on the FJ400 makes it simple to use your preferred softbox with it. The FJ400 comes with a Rapid Box Switch Bowens Insert that enables you to link your strobe with any Rapid Box Switch light modulator as well as a Magnetic 5-inch Reflector, Magnetic CCT Gel Set (CTO, 1/2-CTO, Window Green, Diffusion, Gel Frame), and Magnetic CCT Gel Set. Large umbrellas and modifiers can be mounted and positioned securely using the built-in tilter bracket with a tension screw.

Safety-Conscious Design

For safe operation while in use, the FJ400 strobe has onboard self-monitoring cooling fans and an automatic shutoff mechanism.

Easily Transport and Store Your Strobe Kit

The supplied backpack is perfect for comfortably transporting your FJ400 gear since it has a sizable central storage section with detachable partitions. A compact water bottle pouch, a tripod holder with retention straps, different zipped sections for storing smaller supplies, an inside box with three padded sleeves for holding computers and tablets, and more are included.
