For Pentax photographers, the Godox AD400Pro Witstro All-In-One Outdoor Flash with XProP TTL Trigger Kit from B&H bundles the 400Ws battery-powered monolight with a dedicated radio trigger for Pentax TTL flash systems.
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.

For ensuring maximum reliability and control, users can set up 16 groups on one of 32 channels and can then access 99 wireless ID settings for limiting interference from other nearby systems.

Users can adjust flash exposure compensation from -3 to +3 EV as well as wirelessly control the modeling light, zoom setting, and more. For using the XProP with other camera systems there is a 2.5mm sync port that supports triggering via a wired connection. Also, a USB-C port is present for firmware updates and the devices run on two AA batteries for convenience.
