Check availablity: Adorama, Amazon USA, Amazon UK, B&H, eBay.

Sigma's rectangular fisheye sports a bright maximum aperture of f/2.8, and a fast and quiet ring motor (HSM). The lens is designed for use with digital SLR cameras equipped with DX sized image sensors (or smaller). Unlike most fisheye lenses, who provide a 180° circular image, this lens provides a conventional retangular image. On Nikon DX (1.5x crop), it produces a diagonal field of view of 180°, on Canon (1.6x crop) the field of view is 167°, and on Sigma (1.7x crop) the field of view is 154°.

Sigma is a family owned manufacturer of photographic equipment founded in 1961 in Japan. The company's main business is to manufacture third party lenses. However they also produce third party flash units and, since 2002, their own line of DSLR and compact cameras. Sigma's digital cameras use a special sensor, developed by Foveon, that records full color information for every pixel. In late 2008 Sigma acquired Foveon.
