The Nikon D7000 is a new prosumer DSLR camera with a 16.2-megapixel DX-format image sensor which was announced in September 2010, the first digital SLR with movie capture capability and the first mid-range model with a high-res 3.0-inch VGA LCD panel. Externally, the Nikon D7000 is similar to its predecessor in terms of size, weight, and much of the controlled layout, but adopts a weather-sealed, magnesium alloy construction like that of the D300S.
