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.
