Pentax smc DA* 16-50mm f/2.8 ED AL (IF) SDM Lens

The Pentax SMC DA* 16-50mm f/2.8 ED AL IF SDM is an APS-C standard zoom lens built for Pentax’s K-mount DSLR system and part of Pentax’s DA* series, representing the higher tier of optical and mechanical standards within the DA lens lineup. Covering a focal range equivalent to approximately 24-75mm in full-frame terms with a constant f/2.8 maximum aperture throughout, it addresses a practical everyday shooting range from moderate wide-angle through short telephoto suited to travel, portrait, street, and general-purpose photography. Extra-low Dispersion and aspherical glass elements help control chromatic aberration, distortion, and aberrations across the zoom range, and the SDM supersonic drive motor delivers quiet and smooth autofocus performance suitable for both stills and video use. Internal focusing keeps the overall lens length constant during focus operation, and weather resistant sealing makes it suitable for use in light rain and dusty conditions when paired with a compatible weather-sealed Pentax K-mount body.
