An all-in-one zoom for APS-C cameras, the 18-300mm f/3.5-6.3 DC MACRO OS HSM Contemporary Lens from Sigma provides users of Pentax K-mount cameras with an extremely versatile focal length equivalent of 28.8-480mm. This version also offers optical image stabilization for reducing the effects of camera shake at longer focal lengths and slower shutter speeds.
