The Nikon SB-910 Speedlight is Nikon's flagship flash unit--the most
advanced in the Speedlight range. The SB-910 advances Nikon's lighting mastery
by providing easy operation and menu navigation, with a newly simplified graphic
user interface (GUI).  A dedicated Menu button with quick access to custom
settings also simplifies the flash operation. The improved thermal protection
system prevents overheating during rapid firing by automatically slowing down
the recycle time rather than shutting down the flash. Hard filters for
fluorescent and tungsten lighting are included, and the flash automatically
changes the camera's white balance to match the filter in use.

The automated zoom head covers 17mm to 200mm lenses (in 35mm/FX
format), and can cover this range in just 1.2 seconds.  This flash lets you
select from three light distribution patterns: Standard, Center-weighted, and
Even. It will also automatically detect if it is connected to a DX or FX format
camera, and adjust itself accordingly.

The SB-910 can work as a stand-alone flash, or as part of a wireless group,
either in Commander mode or as a slave (remote). The i-TTL system in this flash
supports Advanced Wireless Lighting and versatile functions for up to four
groups of Speedlights, with 3 remote i-TTL Speedlight groups controlled through
the master SB-910. i-TTL Balanced Fill-Flash flash control employs Nikon's
Advanced Data Communication System. This system provides an improved method for
the monitor pre-flash and wireless operation that marks an evolution in higher
precision--it forms the core of the Creative Lighting System.

Note! Please note that the SB-910 is only
fully compatible with DSLR cameras that support i-TTL operation. With older
cameras that use the D-TTL mode, only [A] Auto mode (non-TTL) is
available.
Multiple Flash Exposure Modes

Advanced Thermal Protection

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.

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.

FV Lock
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.

Colored Gels
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.

Color 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

coverage from 20-105mm.
