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

Designed to provide a full 180° circular fisheye image on a Four-Thirds body (2.0x crop).

However, on 1.5x crop bodies, a lot of pixels are wasted around the edges.

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.
