Characterized by its versatile zoom range and bright design, the Nikon F-mount 17-50mm f/2.8 EX DC OS HSM from Sigma covers a wide-angle to portrait-length range and features a constant f/2.8 maximum aperture to excel in available light conditions. The optical design incorporates a pair of low dispersion elements along with a trio of aspherical elements to reduce a variety of aberrations and promote greater sharpness and clarity. A Super Multi-Layer Coating is also used to suppress flare and ghosting for improved contrast and color accuracy. Benefitting the optics, a Hyper Sonic Motor affords quick and quiet autofocus performance while an Optical Stabilizer minimizes the appearance of camera shake for sharper handheld shooting. Additionally, the lens is distinguished by its sleek profile, making it an ideal lens for walkaround and travel shooting.Manufacturer Included Items:Sigma 17-50mm f/2.8 EX DC OS HSM Lens for Nikon FLCF-77 III 77mm Lens CapRear Cap LCR II for Nikon F Mount LensesLens Hood for 24mm f/1.8 EX Digital, 17-50 f/2.8 EX, 28mm f/1.8 EX LensLens CaseBundle Items Include:1 x Sigma 17-50mm f/2.8 EX DC OS HSM Lens for Nikon F1 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
