The AD400Pro flash from Godox features a 2.4GHz wireless X-system with a range of up to 328 feet, compatible with many TTL systems, including options from Canon, Nikon, Sony, Fujifilm, Olympus, and Panasonic. It delivers up to 400W, ranging from 1/1 to 1/256, and comes with a powerful 21.6V/2600mAh lithium battery that provides up to 390 full-power flashes for outdoor and location shooting. Alternatively, you can run the monolight on AC power using an optional adapter. It also features a high-speed sync mode that operates at shutter speeds up to 1/8000 sec, providing flash durations of 1/240 to 1/12820 sec. Another unique setting is the Stable Color Temperature mode, which tightly controls color to maintain temperature variations within ±75 K across the entire power range. Despite these impressive features, it manages to keep recycle times low at 0.01-0.9 seconds to capture the speed of movement and every fleeting gesture. There's also a 30W LED modeling lamp to help you preview how the light will fall on your subject.
