Westcott FJ400 Overview

The FJ400 Strobe 2-Light Backpack Kit with FJ-X3m Universal Wireless Trigger from Westcott is a comprehensive assemblage that combines the FJ400 Strobe with accessories that allow you to make the most of the fixture. The kit contains two FJ400 Strobes with batteries, each with a diffusion dome, AC adapter and cord, magnetic reflector, magnetic gel set, and a USB cable. A Lite Traveler Backpack to carry it all.

The FJ400's, lithium-ion battery that will give you 480 full-power flashes on a two-hour charge. The FJ400 has a nine-stop power range in 0.1 stop increments and recycles in a fast 0.5 to 0.9 seconds. It is backed by a 1/19,000 peak action-stopping flash duration in Freeze Mode, is capable of 20 fps, and supports High Speed Sync up to 1/8000 second as well as front and rear curtain sync.

One of the FJ400's exciting features is its TTL option. The flash has an integrated 2.4 GHz receiver that has 16 channels, and 32 groups that with an FJ-X3m trigger will accept TTL signals at a distance of up to 985' from Canon, Nikon, Sony (with adapter), FUJIFILM, Panasonic Lumix, and Olympus cameras.
