Nikon D300 digital single lens reflex:
The Nikon D300 is loaded with the latest professional technologies designed to produce images of the highest quality. The high-resolution 12.3 MP DX format CMOS sensor generates image files suitable for almost every type of output, combined with a fast standard frame advance rate of 6fps (up to 8 fps with optional Multi Power Battery Pack).

NikonD300 D-SLR camera - Anti dust and Sensitivity:
The new Nikon D300 offers fast power-up, quick response and outstanding flexibility to meet the needs of a wide variety of photographic assignments. The Nikon D300 powers-up in just 0.13 seconds, with an almost imperceptible 45 millisecond shutter lag. The Nikon D300 D-SLR camera boasts a self-cleaning sensor unit, which vibrates at high frequencies to remove any loose dust on the surface of the sensor’s optical low pass filter. The camera has a broad ISO range from 200-3200 plus Lo 1 (the equivalent of an ISO 100) and Hi (ISO 6400 equivalent). Image accuracy is also enhanced by the new Nikon Scene Recognition System, which uses the acclaimed Nikon 1005-pixel RGB colour sensor modified to recognize subjects’ shape and position before the image is captured. This also aids the new 51-Point Autofocus system in tracking subjects by their colour, while enhancing the accuracy of exposure and white balance metering. The Nikon D300 also offers Live View, which presents photographers with a live image on the LCD screen, with two modes suited to either hand held or tripod shooting. Autofocus is possible in both Live View modes.

Nikon D300 SLR - VGA display and Information panel:
The Nikon D300 is completely high definition. From the 3-inch VGA LCD screen with 170-degree viewing angle, to the HDMI interface for HD ready displays, the Nikon D300 is ready for tomorrow’s imaging environment. The controls of the Nikon D300 were designed for ease of use, with an easy-to-view top LCD panel and an information display on the rear LCD screen that can change colour according to the ambient lighting conditions. The totally intuitive 8-directional multi-area selector makes selecting any of the 51-Point autofocus settings simplicity itself.

Nikon D300 camera - Durable and Dependable:
The Nikon D300 single lens reflex continues Nikon’s long tradition of sturdiness and durability. The camera body is built from a magnesium alloy, while the camera’s shutter has been tested for 150,000-release cycles. The Nikon D300 is also designed for a high level of dust and water resistance.
