Professional i-TTL (intelligent TTL) Speedlight
Compatible with FX- and DX-format SLR cameras. Part of the Nikon Creative Lighting System, it offers total control over flash coverage.
Centre-weighted, Even and Standard illumination patterns
Centre-weighted mode concentrates illumination to the centre of the frame, useful when using a telephoto lens. Even mode diffuses light evenly across the frame, useful when taking group shots. Standard mode offers a standard balance of power and light distribution.
17-200mm auto zoom range
Offers a 14mm zoom range when using built-in diffuser or Speedlight dome.
Boasts a large LCD screen, clear menu systems, conveniently placed controls and illuminated buttons that offer more comfortable operation in low light.
Automatic detection of sensor format
Automatically recognises FX- or DX-format cameras.
Recycling time of 2.3 seconds when using LR6 NiMH batteries.
Compatible with Multi-CAM 3500 FX/DX AF sensor module.
Rotates 180° horizontally to the right and left; tilts up to 90° and down to 7°.
Thermal protection system
Warns of excessive heat build up during high intensity firing.
Hard-type incandescent and fluorescent colour filters included.
Automatic filter detection
Speedlight automatically adjusts the attached camera's color temperature settings according to the color of the filter being used.
Can be upgraded via the storage media in the attached camera.
- Multiple Flash Exposure Modes
- i-TTL Balanced Fill-Flash with Nikon cameras that support i-TTL (e.g. D3, D700, D200, etc.)
- AA Auto Aperture Flash
- A Auto Aperture Flash with many film SLRs, including the Nikon N55 (F55) and FM10
- M Manual Flash
Advanced Thermal Protection
Advanced thermal protection system slows the flash recycle time, rather than simply shutting down to prevent overheating
Flash head tilts down to 7° or up to 90° with click-stops at -7°, 0°, 45°, 60°, 75°, 90°.
Flash head rotates horizontally 180° to the left and right with click-stops at 0°, 30°, 60°, 75°, 90°, 120°, 150°, 180°
111.5'/34 m (at ISO 100, 35mm zoom head position, in FX format, standard illumination pattern, 68°F/20°C) to 157.5'/48 m (at ISO 200, 35mm zoom head position, in FX format, standard illumination pattern, 68°F/20°C)
Intelligent i-TTL system supports Advanced Wireless Lighting and versatile functions for up to 3 remote i-TTL Speedlight groups controlled through a master SB-900 or with the 'Commander' function of compatible cameras.
3 Light Distribution Patterns
Allows you to improve the light quality by selecting Standard for general illumination, Center-weighted for portraits, or Even for groups and interiors.

2.3 sec. (approx.) with Ni-MH (2600 mAh) batteries
3.0 sec. (approx.) with Oxyride (1.5V) batteries
4.0 sec. (approx.) with Alkaline-manganese (1.5V) batteries
4.5 sec. (approx.) with Lithium (1.5V) batteries
Mixed Exposure Modes
Individual flash mode settings (TTL, AA, A and M) are available for each of the four groups (including master controller) for easy total lighting control based on the brightness of the subject and not simply on general output ratios for each group.
Flash Value Lock allows photographers to change the composition or zoom for the shot while maintaining desired lighting of the subject.
Distance Priority Manual Flash Mode
User can set the distance and aperture, and the SB-900 automatically sets the power output, a great feature for manual flash M shooting at weddings and for product shots.
Allows modification of flash output to match background scene, especially useful for digital cameras where 'white balance' can be controlled. Included are Tungsten and Fluorescent adjustment filters.
Coluor Gel Filter Identification
Flash automatically identifies mounted color gel filters and adjusts the camera's auto white-balance setting with select Nikon digital SLR cameras.
Flash Tube Overheat Protection
Includes a built-in thermal sensor that protects the flash-tube from overheating during sustained high-speed bursts.
Wireless Flash Modes Master
The SB-910 provides improved AF assisting accuracy by being able to cover all 51 AF points with the D3, D700, and D300 (as of 7/2008), and with wider coverage from 20-105mm.
