Quick Review: The D300 is the latest incarnation of Nikon's popular semi-pro series of digtal SLRs, which began with the D100 first introduced all the way back in 2002. With the D300, Nikon has made the switch to a CMOS based sensor (manufactured to Nikon specs by Sony), which not only adds 2 megapixels to the D200's 10mp, but even manages to achieve less image noise in low-light situations. For many photographers, this may be one of the best reason to upgrade, but that's only part of the story; the D300 is a major upgrade from the D200, and the list of improvements is extensive. These include a much better 51 point auto-focus system, 6 frame-per-second continuous shooting, self-cleaning sensor, EXPEED image processor, 14-bit A/D conversion, 3" 922,000 pixel LCD with live preview, HDMI video output, "Active D-Lighting", better battery life, and more.

The D200 was a popular and well-spec'd camera that exceeded the requirements of most non-professional photographers. The D300 is even better and has enough real improvements (particularly the new auto-focus system) that it competes almost too well against some of Nikon's high end cameras like the D2X and D2H series, yet costs significantly less. This may be the most expensive camera in its niche (chief competitors are the Canon 40D and new Sony A700) but it offers a level of professional features previously unavailable at this price point.

Pros: image quality, rugged build, weather resistant, improved ISO noise performance compared to D200, flash system, built-in sensor dust removal, live LCD preview, improved battery life compared to D200.

Cons: Price, high ISO grain (compared to Canon 40D)
