Frequently Asked Questions
What camera systems does the FJ400 support for TTL and HSS?
The included FJ-X3m trigger provides TTL, HSS, and manual control across multiple camera systems. The trigger communicates wirelessly with the strobe, so you get full TTL metering and high-speed sync up to 1/8000s regardless of your shooting pace.
Can I use this strobe on location without AC power?
Yes. The FJ400 runs on a 14.8V lithium-ion polymer battery that delivers approximately 480 full-power flashes per charge. You can shoot an entire portrait session or event on a single battery, then switch to AC power in the studio.
What light modifiers are compatible with the FJ400?
The FJ400 uses a Bowens S Mount, which is the most widely supported modifier mount in the industry. Any Bowens-compatible softbox, beauty dish, or reflector will attach directly without adapters.
How consistent is the color temperature across the power range?
The FJ400 holds 5500K within +/-150K in Normal, TTL, and HSS modes. This means you can adjust power between shots during a session and maintain consistent white balance without heavy correction in post.
What is the continuous shooting capability for fast-paced work?
The strobe supports burst shooting up to 20 frames per second with a recycle time as fast as 0.05 seconds at lower power settings. At full 400Ws output, recycle time is 0.9 seconds.
