Sigma 18-35mm f1.8 DC Art HSM Lens for Canon EF

The Sigma 18 35mm f1.8 DC Art HSM Lens is the first wide angle zoom lens as of 22nd April 2013 to achieve a maximum aperture of f1.8 throughout the entire zoom range. This lens incorporates a wide glass moulded aspherical lens with Special Low Dispersion SLD glass to compensate for aberrations and curvature at the widest angle. It has a 9 blade rounded diaphragm to create attractive round bokeh at large aperture settings, and an inbuilt HSM Hyper Sonic Motor that ensures a silent, high speed AF. Ideal for landscapes, portraits, still life, snap shots, casual, and close ups, this lens is suitable for cropped APS C sensor cameras.
