The SB-910 is a high-end Speedlight for advanced amateur to professional photographers that offers a number of improvements over its predecessor, the Nikon Speedlight SB-900.

A refined user interface for smoother operation. Users can now quickly access custom settings using the new MENU button. In addition, the graphical user interface (GUI) has been improved to offer simpler application of settings for all operations.

Three illumination patterns for use according to the scene. The SB-910 offers selection from three illumination patterns (Standard, Even, Center-weighted), allowing users to choose the pattern most appropriate for the scene. Illumination precision has also been increased.

Automatic detection of hard color filters attached to the front of the flash head
The SB-910 supports hard color filters because they are more durable, stand up better to the heat generated by the flash head, and are easier to use than the gel color filters supported by its predecessor. One incandescent filter and one fluorescent filter are supplied with the SB-910.
