Nikon Speedlight SB-900
July 1, 2008
Advanced, high-performance Speedlight for Nikon digital SLR cameras
TOKYO – 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-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.
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.
*The world’s first flash unit with a user-applied firmware update function via a digital SLR camera as of July 1, 2008 (according to research conducted by NIKON CORPORATION).

Nikon Speedlight SB-900 Major Features
- Multi-step auto zoom covers wide 17-200mm zoom range (24-105mm：SB-800)
- Three illumination patterns (standard, center-weighted and even) are available to match each shooting environment
- Automatically detects Nikon FX and Nikon DX formats and selects suitable light distribution
- Improved booster circuit for high-speed recycle time: Recycle time using four AA-size batteries is almost equal to the SB-800 with five AA-size batteries
- New AF-Assist illumination covers a wide 20-105 mm focal range compatible with the new Multi-CAM3500 FX/DX AF sensor
- Firmware update via Nikon D3 and D700 is possible (world’s first*)
- Thermal Cut-out function limits the number of flashes to avoid deterioration of light emitting parts caused by continuous flash firing
- Automatically detects color filters (fluorescent or incandescent), enabling camera to control color temperature according to filter information from SB-900
- Improved switch panel for enhanced usability
- Improved GUI using a large-size LCD dot panel
- Bounce capability: tilts up to 90º, down to -7º, rotates horizontally 180º to right and left
- Advanced Wireless Lighting and versatile functions for up to three remote groups of SB-900s or other compatible Speedlight controlled through the master SB-900
- Optional Water Guard WG-AS1 (for D3), WG-AS2 (for D300), and WG-AS3 (for D700) is useful for protecting the camera's hot shoe contact when the SB-900 is mounted on these Nikon digital SLR cameras
*The world’s first flash unit firmware update function via a digital SLR camera as of July 1, 2008 (according to research conducted by NIKON CORPORATION).
