The Sigma 12-24mm f/4.5-5.6 EX DG HSM is a professional-level wide-angle zoom lens made by Sigma Corporation.[1] It was once the widest rectilinear lens available (with this distinction has since been taken over by Canon EF 11-24mm f/4L) for full-frame 35mm SLR cameras, providing a field of view of 122 degrees. It is still the widest full-frame rectilinear lens available for Nikon as of 2016. This distinction has been taken over by the Irix 11mm f/4 lens released in 2017[2]. However, the Sigma lens still remain the widest autofocus full-frame zoom lens available for Nikon camera as the Irix lens is a manual focus prime lens. Other lenses available with focal lengths of 12mm or less are either incompatible with full-frame cameras or are intentionally distorted. The Sigma 12-24 has low distortion even compared to less wide zooms like the Canon EF 16-35mm lens.[3]

This lens is available in Canon, Nikon, and Sigma, Pentax, and Sony mounts. HSM focusing is available only in the Canon, Nikon, and Sigma variants.[4] The build quality is typical of Sigma EX lenses, with a painted metal lens barrel and damped focus and zoom rings. As expected for a lens of these specifications, there is a large protruding front element.[5]
