Just under two years since the D200 Nikon reveals the D300, the range of changes is so significant that it wouldn't be inappropriate to call it a 'compact D3' (less the full-frame sensor of course). From the top there's a new CMOS sensor with twelve megapixels, a new auto-focus sensor with 51-points (15 of which are cross-type sensitive), there's focus tracking by color, scene recognition, Picture Control presets, six frames per second continuous shooting (or eight frames per second with a battery pack), Compact Flash UDMA support, Live View (with contrast detect AF) and the mighty impressive 3.0" 922,000 pixel LCD monitor (oh and HDMI video output). It's an impressive list, the D200 was a fair step up from the D100, the D300 can be seen as just as big a step, certainly more than enough to make the competition sweat.
