The Nikon D90 --- First and foremost there\'s a new CMOS sensor, which Nikon claim produces D300 quality output at up to ISO 6400 and - one of several features to \'trickle down\' from higher models - the same highly acclaimed 3.0-inch VGA screen as the D3/D300. Naturally it has Live View with contrast-detect AF and it would have been surprising had it not sported some form of dust removal system. More surprising is the inclusion of the world\'s first DSLR movie mode (720p HDTV quality, no less) and HDMI output, though as we\'ll see later it does come with some limitations. A lot of the core photographic spec is the same as or very similar to the D80, though there is a new shutter and an implementation of the 3D tracking AF seen on the D3/D300.

The D90\'s sensor, which is much larger than the sensor of a typical camcorder, ensures higher image quality and exceptional low-noise, high ISO sensitivity performance, even during movie shooting.
