Nikon’s DX-format digital SLR cameras with their APS-C sized sensors (approximately 24 x 16 mm in size) have always been more popular than its higher-end FX-format digital SLR cameras which are equipped with a full-frame sensor (approximately 36 x 24 mm in size), and the Nikon D90 is probably the company’s most popular DX-format digital SLR camera to date. The D90, which was launched after the Nikon D300 and before the Nikon D300S, has turned out to be more popular than both the D300 and the D300S, even though the D300 series is the flagship series of Nikon’s DX-format line. The D90’s success formula is clear: its technical quality is almost on par with the D300S, and even slightly better than the older D300 which is supposed to be a higher-end digital SLR camera, but it is sold for a much more affordable price.
The Nikon D90’s highlight feature is without question its newly designed 12.3-megapixel DX-format CMOS sensor, which is claimed to be capable of delivering the same image quality as that of the Nikon D300 at up to ISO 6,400. Another stand out feature offered by the D90 is the inclusion of the world’s first 1280 x 720 High Definition video recording feature in a digital SLR camera. Designed for both beginners and serious amateur photographers, the D90 also comes with an easy user interface inspired by lower-end Nikon digital SLR cameras.
Other features offered by the Nikon D90 include an 11-point phase-detect autofocus system with 3D focus tracking inherited from the higher-end Nikon D300 and Nikon D3, the same 3-inch 920,000 dot resolution TFT LCD screen which is also adopted from the D300 and the D3, ISO 100 – 6,400, 4,5 frames per second continuous shooting speed, a newly designed eye-level pentaprism viewfinder with 96% frame coverage – better than that of the previous Nikon D80, and extensive in-camera retouching features. Looking at all its features, it is not surprising that the D90 has managed to appeal to the broadest audience of any Nikon digital SLR camera.
