Sigma 8-16/4.5-5.6 DC HSM for Canon

Well-suited for landscape, architectural, and interior photography, the Canon EF-mount 8-16mm f/4.5-5.6 DC HSM from Sigma is a sleek ultra-wide zoom featuring quick focusing performance and impressive optics. The optical layout incorporates a series of low dispersion glass elements, which reduce chromatic aberrations and color fringing, along with three aspherical elements to minimize distortion and spherical aberrations for improved sharpness. Individual elements also feature a Super Multi-Layer Coating that controls ghosting and flare to better suit working in bright and backlit conditions. Complementing the lens design is a Hyper Sonic Motor, which promotes fast, quiet, and precise autofocus, along with full-time manual focus override, and a built-in lens hood is also incorporated to further protect the front lens element and guard against flare.
