Sigma Art Wide Angle Zoom Lens 18-35mm f/18 for Sigma SA Camera Lens

Truly a revolutionary product, the Sigma 18-35mm 1.8 DC HSM is the first wide-angle to standard zoom lens to achieve a large aperture of 1.8. Designed specifically for APS-C sized sensors, the Sigma 18-35mm 1.8 translates to 27mm-52.5mm on a 35mm camera. Tapping into Sigma's long history of lens innovations, the 18-35mm 1.8 DC HSM incorporates a wide glass-molded aspherical lens with Special Low Dispersion (SLD) glass to compensate for aberrations and curvature at the widest angle. Internal focusing and zooming allow for more usability and functionality. The 18-35mm is ideal for landscapes, portraits, still, life, snap shots, casual, and close-ups and the Hyper Sonic Motor (HSM) ensures smooth, fast, and accurate autofocusing. The use of Thermally Composite Material (TSC) reduces size and weight but increases the lens's durability. Its new Global Vision design works with its compatibility with the Sigma USB dock for further customization. .
