The Canon EF mount Sigma 50mm f/1.4 DG HSM Lens is a fast standard-length prime designed to achieve high optical performance through the incorporation of both three Special Low Dispersion glass elements and one molded glass aspherical element. These elements, coupled with an advanced optical design, work to minimize sagittal coma flare and chromatic aberrations in order to provide high image sharpness and clarity. The lens' large diameter and floating system also help to correct for vignetting to ensure maintained peripheral brightness. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity. A Hyper Sonic AF Motor, along with an optimized AF algorithm, produces quiet, smooth, and fast autofocus performance that benefits this lens' use in a wide variety of situations. This AF motor also permits full-time manual focusing control for refined precision by simply turning the focus ring at any time.Manufacturer Included Items:Sigma 50mm f/1.4 DG HSM Art Lens for Canon EFLCF III 77mm Front Lens CapLCR II Rear Lens Cap for Canon EFLH830-02 Lens HoodLens CaseBundle Items Include:1 x Sigma 50mm f/1.4 DG HSM Art Lens for Canon EF1 x 77mm Graduated Color Multicoated 6pcs Filter Set1 x 77mm 4-Piece 1 2 4 10 Close-Up Macro Filter Set with Case1 x Heavy Duty Lens Case for Camera Lenses1 x 77mm 3 Piece Filter Kit1 x Full Size Deluxe Tripod1 x Secure Digital High Speed 32GB Memory Card1 x Lens Cleaning Solution1 x Cleaning Cloth1 x Dust Blower1 x Lens Pen1 x Memory Card Wallet1 x USB Card Reader1 x Microfiber Cloth
