18-300mm f/3.5-6.3 DC Macro OS HSM
Zoom lens for Pentax
The Sigma 18-300mm f/3.5-6.3 DC Macro HSM Contemporary lens is a very versatile lens for APS-C Pentax K-mount cameras. This lens offers a Hyper Sonic Motor (HSM) for quick and quiet autofocusing. Special Low Dispersion (SPD) and "F" Low Dispersion (FLD) elements are also included to provide greater image clarity and contrast and minimize chromatic aberration. A Super Multi-Layer coating has been applied to the elements to reduce flare and improve contrast.
