I have owned several Nikon Speedlights in the past ten years, including, SB-28, SB-80DX, SB-800 and SB-900. Today Nikon has announced the SB-910, the flagship flashgun in its Speedlight range, replacing the SB-900. I will probably upgrade to the new SB-910, to benefit the better handling; the enhanced operating system featuring illuminated function buttons, a dedicated Menu button with quick access to custom settings and an improved LCD screen with graphic user interface first seen on the less powerful SB-700, the SB-910 Speedlight is designed to provide easy operation and menu navigation. The new hard-type Colour filters are also supplied instead of the flimsy soft ones.
SB-910 Primary Features:
* 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.
* 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 colour filters attached to the front of the flash head - the SB-910 supports hard colour 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 colour filters supported by its predecessor. One incandescent filter and one fluorescent filter are supplied with the SB-910.
Additional SB-910 Features and Functions:
* Guide number of 34/111.5 (at ISO 100, m/ft., 35-mm zoom head position, in FX format, standard illumination pattern) for high flash output volume.
* Power zoom function with which the SB-910 automatically adjusts the zoom head position to match lens focal length - FX format, Standard illumination pattern: 17–200 mm (14 mm with the built-in wide panel in place) DX format, Standard illumination pattern: 12–200 mm (10 mm with the built-in wide panel in place).
The new flash is just an evolution - a minor tweaked SB-900, a firmware upgrade could have done it to the old one, but anyway I'm getting one of these in near future I'm sure. Some questions remain: where are the radio controlled flash system and the video-light feature???
