Nikon's replacement of the SB-900 i-TTL Speedlight, the Nikon SB-91, is a fast, powerful, portable light that features a re-designed menu system and controls. It will be available from 15 December 2011 with an RRP of £449.99.
The SB-910 offers extensive opportunities for on-camera or wireless flash photography and offers enhanced operation with an extended zoom range of 17-200mm and three illumination patterns for total control over flash coverage. It offers Centre-weighted, Even and Standard illumination patterns and bounce flash capability is provided through a head that can be tilted up to 90º, down to 7º and rotated horizontally through 180º to the right and to the left.

Menus are clearer and the selector dial incorporates a groove so you can feel when you change settings. Illuminated buttons offer better visibility in the dark and the SB-910 includes hard cover (plastic) colour filters that are more durable and easier to attach.
