The Sigma 18-200mm 3.5-6.3 DC HSM OS lens is the second addition to the Contemporary line from Sigma?s Global Vision. The Sigma 18-200mm lens was designed for APS-C sensors and features a new matte black finish, thermally stable composite material in its construction and smaller and lighter design then previous models. With exceptional performance, this 18-200mm camera lens does not sacrifice image quality for versatility. Having the ability to shoot from wide angle to telephoto is highly useful particularly for travel photography, landscape photography, street photography, portrait photography and nature photography. An improved minimum focusing distance of 14.7 inches paired with the use of Special Low Dispersion glass, the 18-200mm excels at bringing out great detail in close-up photography as well. A Hyper Sonic Motor (HSM) ensures quiet, accurate and fast autofocus and an optical Stabilizer (OS) helps compensate for camera shake. Make this lens your all-in-one lens to handle any shooting scenario. SPECIFICATIONS Lens Construction 16 Elements in 13 Groups Angle of View 76.5?-8.1?
