The Sigma 10mm f/2.8 EX DC fisheye is a photographic lens manufactured by Sigma Corporation. It is a diagonal fisheye lens. Unlike most fisheye lenses, this lens is designed for digital SLR cameras that do not have a full 36x24mm sensor^[1]. This results in a much greater fisheye effect than is possible when a full-frame fisheye lens is used with a smaller sensor.

This lens is available in Canon, Nikon, and Sigma, Pentax, and Sony mounts.
