The SB-900 is a high-performance Speedlight developed as the successor to the hugely successful Nikon SB-800. Practical functionality was emphasized in designing the SB-900, especially evident when used with Nikon digital SLR cameras compatible with the Nikon Creative Lighting System. It provides a wide 17-200 mm auto zoom range (expanded from the SB-800’s 24-105mm), three illumination patterns, newly designed, streamlined operation with a full-information LCD panel, and AF-Assist illumination compatible with new-generation AF sensors.
The SB-900 has an improved booster circuit for high-speed recycle time. In addition, firmware can be uploaded via a Nikon digital SLR camera—a world’s first* for flash units, assuring that the SB-900 can accept technological advancements. The SB-900 serves as the new core for the Nikon Creative Lighting System when used in combination with current Nikon digital SLRs, and it supports Advanced Wireless Lighting as a master or a remote Speedlight, inviting photographers to explore the many creative possibilities.
