Sigma 12-24mm ultra-wide reaching 12mm on full frame, one of the widest rectilinear zooms at moderate pricing.
The Sigma 12-24mm f/4.5-5.6 II DG HSM is the second generation of Sigma's ultra-wide full-frame zoom reaching 12mm — one of the widest rectilinear zooms available for any full-frame system. The Mark II improves optical quality and AF performance over the original.
The 12mm provides a 122-degree field of view on full frame — among the widest rectilinear perspectives available without fisheye distortion. The HSM motor provides fast, quiet autofocus, and the DG full-frame coverage enables dramatic ultra-wide compositions on full-frame Canon EF bodies.
Build quality is Sigma with the improvements of the Mark II revision. The bulbous front element prevents front filter use, but the extreme 12mm capability provides perspectives that no narrower zoom can achieve for architectural and landscape photography.
The Sigma 12-24mm II offers one of the widest full-frame rectilinear zooms at moderate used pricing. The 12mm capability provides perspectives impossible with any narrower zoom — essential for extreme wide-angle architectural and landscape work.
