Nikon has today unveiled a new flagship i-TTL Speedlight flash in the shape of the SB-910.

Replacing the SB-900 Speedlight, the SB-910 features an extended zoom range of 17-200mm and three illumination patterns to control flash coverage: centreweighted, even and standard.

It also boasts ?refined ergonomics? and clearer menus.

Illuminated buttons should help it easier to use in the dark, for example.

The flash head can be tilted up to 90 degrees, down to seven degrees and rotated 180 degrees horizontally, according to Nikon.

The SB-910 is due to go on sale on 15 December, priced £449.99.
