Reliable 400Ws power and control are advantages of the AD400Pro II All-in-One Outdoor Flash from Godox. The brand continues to expand its Witstro series by improving the popular AD400Pro to a second version with group color indicator capability, a local 2.4" color screen, and the addition of a larger 30W, bi-color, LED modeling light. The AD400Pro II provides users with customized 1/512 to 1/1 power output, and the flash offers several professional and convenient features, such as full TTL support to work with the auto flash systems of Canon, Nikon, FUJIFILM, Olympus, Sony, Leica, and Pentax cameras. The flash head has a recycle time of 0.1-1 sec and a convenient action-stopping freeze mode. The AD400Pro II weighs in at 4.4 lb, which is similar to its previous model so it is still portable enough to carry around. The bare flash tube, reflector, and detachable battery make the AD400Pro II ideal for outdoor shooting.
