The Nikon D90 is a 12.3-megapixel digital single-lens reflex camera model announced by Nikon on August 27, 2008. It is a prosumer model that replaces the Nikon D80, fitting between the company's entry-level and professional DSLR models. Nikon gives the D90's Estimated Selling Price in the United States as US$899.95 for the body alone and as $1299.99 with the Nikkor AF-S DX 18-105mm f/3.5-5.6G ED VR, which by itself sells for $399.95. Street prices are generally lower.
The D90 was the first DSLR with video recording capabilities. In May 2009, the D90 won the TIPA European Photo & Imaging Award, in the "Best D-SLR Advanced" category.
Some of the improvements the D90 offers over the D80 include 12.3 megapixel resolution, extended light sensitivity capabilities, live view and automatic correction of lateral chromatic aberration. The D90 is the first DSLR to offer video recording, with the ability to record HD 720p videos, with mono sound, at 24 frames per second.
Unlike less expensive models such as the D40, D60, D3000 and D5000, the D90 has a built in autofocus motor, which means that all Nikon F-mount autofocus-lenses (except two for the rare Nikon F3AF) can be used in autofocus mode.
The Nikon D90 is the first Nikon camera to include a third firmware module, labeled "L," which provides an updateable lens distance integration database that improves autoexposure functions. Some of its accessories, such as the MB-D80 battery grip and ML-L3 wireless remote, are also compatible with its predecessor the D80. It supports Global Positioning System integration for automatic location tagging of photographs, using a GPS receiver sold separately.
