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

Sigma 18-35mm f/1.8 DC HSM Art lens designed for Canon EF-mount cameras using APS-C sensors. On a 35mm camera this zoom covers an effective focal length of 28.8-56mm. It offers a constant aperture range from f/1.8 to f/16 for strong low-light capability and precise depth-of-field control. Optical construction features four aspherical elements and five SLD glass elements, and a Super Multi-Layer Coating helps reduce flare and ghosting for improved contrast and color fidelity.
