"Nikon has announced the SB-910, the flagship flashgun in its Speedlight range. Replacing the SB-900, the 910 gains the simpler graphic user interface (GUI) of the less powerful SB-700. Its more advanced thermal protection system slows the flash recycle time, rather than it simply shutting down to prevent overheating. It comes with hard filters for matching fluorescent and tungsten lighting and automatically switches the camera's white balance to match the filter. Similarly it adjusts the available zoom steps to suit the body (FX or DX) that it's attached to. The SB910 will be available from mid-December, priced around $549.95."
