Free yourself from the hassles of cable management and demanding optical alignments with the Nissin Air 1 Commander for Nikon cameras. It features the latest Nissin Air System with a 2.4GHz radio transmission that allows wireless triggering of flashes from a maximum range of 98 feet. It also features eight channels and three groups that enable you to bind multiple flashes with different modes and settings, all of which are controlled by the Air I Commander. It even supports high-speed syncs with a maximum sync speed of 1/8000 seconds while still retaining compatibility with slower 1st and 2nd curtain sync modes. The NAS can make various adjustments such as focal coverage, power, exposure compensation, and AF-assist to offer absolute control on the lighting conditions.
