Godox AD400Pro Witstro 400W Cordless Portable Outdoor TTL Flash Strobe

The Godox AD400Pro 400W Witstro All-In-One Outdoor Flash is similar to the larger Godox AD600Pro with a sleeker design. The length is only slightly longer than the AD200, however, it is packed with the same features as the AD600Pro with slightly less output at 400Ws. The Bowen S-type adapter is no longer built-in, however, it is provided with the flash to maintain its smaller form factor. You're able to mount different flash modifier mounts included Profoto, Broncolor and Elinchrom should you use lighting modifiers and softboxes from different lighting systems.

The AD400Pro is a versatile and all-in-one solution for flash photographers. It's compatible with several TTL systems including Canon, Nikon, Sony, Fujifilm, Olympus, Panasonic and Pentax. It provides up to 400W of output with nine steps of power, ranging from 1/1 to 1/256, and comes with a powerful 2600mAh / 21.6V lithium-ion battery pack that provides up to 390 full-power flashes, perfect for outdoor or on-location shooting. Alternatively, you can run the monolight on AC power with an optional adapter.
