Sigma 8-16mm f/4.5-5.6 DC HSM Lens for Canon EF

The Sigma 8-16mm f/4.5-5.6 DC HSM is an ultra-wide-angle zoom lens designed exclusively for APS-C format Canon EF-mount DSLRs (providing a 12.8–25.6mm equivalent focal length range). Recognized as one of the widest rectilinear zooms available for crop-sensor cameras, it is exceptionally well-suited for architectural, interior, landscape, and real estate photography. Its advanced optical layout incorporates four F Low Dispersion (FLD) glass elements, one Special Low Dispersion (SLD) element, and three aspherical elements to control distortion, spherical aberrations, and color fringing across the frame. A Hyper Sonic Motor (HSM) delivers rapid, near-silent autofocus with full-time manual focus override, while an integrated petal-shaped lens hood protects the bulbous front element.
