Wireless: The flash has a built-in 2.4GHz X wireless radio system, allowing for wireless triggering and control. Compatibility: The flash is compatible with Nikon’s i-TTL (Through The Lens) system, which means it can communicate with Nikon cameras and provide accurate flash exposure. Guide Number: The guide number is 197 feet (60 meters) at ISO 100 and 200mm, which indicates the maximum distance the flash can effectively illuminate a subject. Zoom Range: The flash has a zoom range of 20-200mm, which means it can adjust its beam angle to match the focal length of the camera lens. There is also a panel that allows it to be adjusted to 14mm. Tilt and Rotation: The flash head can tilt from -7 to 90° and rotate 180° left and right, allowing for precise directionality and control over the light. Wireless Functionality: The flash has master and slave TTL (Through The Light) functionality, allowing it to be used as a master unit or as a slave unit controlled by another master unit. Recycle Time: The flash has a recycle time of 1.5 seconds at full power, which means it can recover quickly after a burst of shots. Sync Modes: The flash supports high-speed sync (HSS) and 1st and 2nd curtain sync modes, which allow for creative control over the flash synchronization with the camera shutter. Overall, this appears to be a professional-grade wireless flash unit designed for use with Nikon cameras and compatible with advanced features like TTL and HSS.
