Sigma 18-35mm F1.8 DC HSM Art - Canon
The Sigma 18-35mm F1.8 DC HSM Art lens is the world's first constant F1.8 zoom. Designed specifically for SLRs with APS-C sized sensors, it covers a 28-50mm equivalent range, and is initially available in Canon, Nikon and Sigma mounts with Sony and Pentax versions to follow. The 18-35mm offers the depth-of-field equivalent of a constant F2.7 on full-frame, and allows the use of lower ISO settings in low light. The lens uses Sigma's Hypersonic Motor for fast, silent focusing, and is compatible with the Sigma USB dock for fine-tuning autofocus calibration. Optically it's one of the finest zooms we've seen.
Distinguished by a uniquely fast and versatile design, the Canon EF-mount Sigma 18-35mm f/1.8 DC HSM is an Art-series zoom, covering wide-angle to normal focal lengths. Separating itself from the pack, this zoom features an exceedingly bright f/1.8 constant maximum aperture, which suits its use in difficult lighting conditions and offers impressive depth of field control throughout the zoom range. The optical design incorporates a series of SLD and aspherical elements, which help to achieve high clarity and sharpness by suppressing various aberrations, color fringing, and distortion. A Super Multi-Layer Coating has also been applied, too, which controls lens flare and ghosting for improved contrast and color accuracy. Balancing the optical merits, this 18-35mm also sports an advanced Hyper Sonic Motor, along with an internal focusing design, to promote fast, quiet, and precise autofocus performance.
