D90

The Nikon D90 is a digital single-lens reflex camera produced by Nikon, released in 2008 as part of the D-series. It is designed for enthusiasts and semi-professionals and follows the D80 in the lineup. The camera uses the Nikon F-mount system and a DX-format image sensor.

The D90 features a 12.3-megapixel DX-format CMOS sensor, an EXPEED image processor, and an 11-point autofocus system. It can shoot about 4.5 frames per second and offers ISO sensitivity from 200 to 3200, with standard exposure modes and metering options. It includes a built-in flash and a 3-inch LCD, and provides both optical viewfinder and Live View for composing images.

A landmark feature of the D90 is its video capability. It was the first DSLR targeted at consumers to record video, enabling 720p HD video at 24 frames per second with mono audio. The camera stores video on SD or SDHC cards and uses a built-in microphone.

The body is designed for durability and ease of use, combining a compact form with a capable feature set and compatibility with Nikon F-mount lenses. Power is supplied by a Nikon rechargeable battery; storage is via SD/SDHC cards.

In its era, the D90 helped popularize DSLRs capable of video and paved the way for Nikon’s later models that expanded on live view and video features. It was eventually succeeded by later mid-range Nikon DSLRs such as the D7000 series.
