Which flash is a great for Nikon Z6 II ?
For a more budget-friendly option, consider the Godox V860III-N. It offers great value with TTL, high-speed sync, and a built-in radio system. I've used it with my Z6 II and it works seamlessly. Plus, it's part of Godox's extensive flash ecosystem if you want to expand later.
The new released Godox V1 Pro is better than V1. You may have a try.
For a versatile flash option, consider the Godox V1(n). This on-camera flash doubles as an external unit with a transmitter. Godox offers numerous accessories, enhancing its utility. While not the most powerful or weakest option, it strikes a balance in performance. The price point is reasonable for its features. Its appealing design is an added bonus.
