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).
Note: 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.
