Pentax smc DA* 16-50mm f/2.8 ED AL (IF) SDM Lens.
A versatile standard zoom characterized by its bright f/2.8 constant maximum aperture, the smc DA* 16-50mm f/2.8 ED AL (IF) SDM Lens offers a 24-75mm equivalent focal length range and is compatible with Pentax APS-C-format DSLRs. The optical design incorporates a pair of aspherical elements and three extra-low dispersion elements to control chromatic aberrations and distortions throughout the zoom range and contribute to a high-degree of sharpness and clarity. A Super Multi-Coating has also been applied to reduce lens flare and ghosting for increased contrast and color neutrality.
