Nikon D2H

Fromhttp://www.robgalbraith.com/ the Nikon D2H sounds cool:

In addition, the Ambience Light Sensor (shown at left)�is able to detect the flicker of artificial lights such as fluorescent, mercury vapour and the like. The flicker is really a strong shift in the colour being emitted by the light source during each on/off cycle (there are usually 50-60 such cycles each second).

As it has been explained to us, once flicker has been detected, the AWB system compensates by applying a different balance frame-by-frame�as needed to counteract the per-cycle colour shift. Egads, if this works it could be of tremendous benefit to sports shooters in particular, since the colour shift really only becomes nasty at action-stopping shutter speeds (1/60 is typically the threshold; above that you'll increasingly experience the problem).
