Featuring a 2.4 GHz wireless X system with a range of up to 328', the AD400Pro Witstro All-In-One Outdoor Flash from Godox is a versatile tool compatible with several TTL systems including Canon, Nikon, Sony, Fujifilm, Olympus, and Panasonic options. It offers up to 400Ws with nine steps of output power, ranging from 1/1 to 1/256, and comes with a powerful 21.6V/2600mAh lithium-ion battery pack that provides up to 390 full-power flashes in outdoor situations and location shooting. Alternatively, you can run the monolight on AC power with an optional adapter. The AD400Pro Witstro features a high-speed sync mode that works with shutter speeds up to 1/8000 second, offering flash durations from 1/240 to 1/12,820 second. Another unique setting is its Stable Color Temperature Mode, which tightly controls color to keep temperature changes within ±75K across the entire power range. Despite these impressive characteristics, it manages to keep recycling times low at 0.01-0.9 seconds to capture peak action and every fleeting gesture. A 30W LED modeling lamp is onboard to help preview how the light is falling on your subject. 2.4 GHz wireless system with a range of 328' (100m), featuring five controllable slave groups and 32 channels Removable handle and stand mount for space-saving packing Compatible with Nikon, Canon, Fujifilm, Sony, Olympus, and Panasonic TTL systems Guide number of 236' (72m) at ISO 100 Can work as an optical slave with S1 and S2 modes Color temperature of 5600K (±200K) Bowens front accessory mount 3.5mm sync cord slot for direct connection, wireless control port, and USB Type-C port for firmware upgrades First curtain and second curtain sync modes Dot-matrix LCD display for on-board control Bowens-type mount for use with compatible accessories
