The Nikon SB-900 Speedlight, the advanced flagship of Nikon's flash units, builds upon the SB-800 with innovative enhancements. Its automated zoom head now covers 17mm to 200mm lenses (in 35mm/FX format) in just 1.2 seconds. You can choose from three light distribution patterns: Standard, Center-weighted, and Even. It automatically adjusts for DX or FX format cameras. The SB-900 can function independently or in wireless groups, either as a commander or slave. Its i-TTL system supports Advanced Wireless Lighting, controlling up to four groups of Speedlights with 3 remote i-TTL Speedlight groups. i-TTL Balanced Fill-Flash control uses Nikon's Advanced Data Communication system, improving monitor pre-flash and wireless operation for higher precision, forming the core of the Creative Lighting System.
