An all-in-one zoom for APS-C cameras, the 18-300mm f/3.5-6.3 DC MACRO HSM Contemporary Lens from Sigma provides users of Pentax K-mount cameras with an extremely versatile focal length equivalent of 27-450mm. The lens also has a maximum aperture range of f/3.5-6.3 and benefits from the inclusion of one SLD and four FLD elements. Additionally, a Super Multi-Layer coating on the elements results in less flare and improved contrast. Utilizing a Hyper Sonic Motor for autofocus ensures quick, quiet, and accurate focusing, all the way to the lens' minimum focus distance of just 15".
