Nikon SB-900 AF Speedlight

Advanced, high-performance Speedlight for Nikon digital SLR cameras

Nikon Corporation is pleased to announce the introduction of the Nikon Speedlight SB-900, a new external i-TTL flash unit with advanced features. The SB-900 offers a powerful guide number of 48/157.5 (ISO 200, meters/feet) and an incredible array of creative flash functions. The SB-900 is an ideal way to solve lighting challenges and extend Nikon D-SLR creativity.

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-800s 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,the latest firmware can be downloaded from our website to a memory card and SB-900 firmware updated while mounted on a Nikon digital-SLR camera with the memory card inserted (Revised on July 10, 2008) -a worlds 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.

Additional new functions include 180 degrees of left or right head swivel, a special built-in overheat protection system and automatic filter detection for unprecedented white balance correction, even in fluorescent lighting conditions.

With the SB-900, users can enjoy all the benefits of the Nikon Creative Lighting System for both automation and comprehensive control, enabling endless lighting possibilities.
