Sigma 18-35mm f/1.8 DC HSM Art Lens for Canon EF

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.
