Similar in build, appearance and quality with the recently released Sigma 35mm F1.4 DG HSM |A and the 30mm F1.4 DC HSM |A, the Sigma 18-35mm 1.8 DC HSM |A is the first wide-angle to standard zoom lens to achieve a large aperture of f/1.8. Designed specifically for APS-C sized sensors, on a Canon EOS APS-C sensor camera 18-35mm translates to 28.8mm-56mm equivalent on a 35mm camera.
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 allows 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 durability. A 9 blade rounded diaphragm also promises a beautiful background blur.
Compatible with the new Sigma Global Vision design, works with the USB Dock and Sigma Optimization Pro for firmware updates and multi-zone microfocus adjustments for further customization.
As Sigma proudly boasts:
"The Sigma 18-35mm 1.8 DC HSM is a new benchmark in photographic history and a must have for every camera bag."
