The Godox Witstro AD600Pro II is a 600 Ws studio flash with 2.4 GHz wireless operation and TTL support for Canon E-TTL II, Nikon i-TTL, Sony, Olympus, Panasonic, Fujifilm, Pentax, and Leica. It syncs with the X3 Flash Trigger using One-Tap Sync and is also compatible with the Godox XproII and X2T. The color TFT display and color-coded indicators for 16 groups make it easier to manage multiple lights.

Freeze mode provides flash durations as short as 1/20400 s (t0.1), while recycling time ranges from 0.01 to 0.9 s. It offers a 10-stop power range from 1/1 to 1/512, a 40 W continuous LED modeling lamp with adjustable color temperature, and high-speed sync support up to 1/8000 s. It is powered by a rechargeable lithium battery and can also operate with the AC26 power supply, which replaces the battery.
