Designed to deliver top optical performance, the Pentax 60-250mm f/4 ED DA* SDM Autofocus Lens is a versatile telephoto zoom lens. Combining advanced technologies including super-low-dispersion optical elements, extra-low dispersion (ED) optical elements and Pentax original lens coatings, this multipurpose lens assures outstanding image quality with clear, high-contrast images, even at image field edges.
It features water and dust resistant sealing for reliable operation in inclement conditions, and a Pentax Quick-Shift Focus system allowing instant auto-to-manual focus switching. The objective lens surface is treated with the Pentax original Super Protect (SP) coating. This special fluorine compound is applied to the lens surface through a vapor deposition process creating a surface that effectively repels dust, water and grease, making it easy to wipe off fingerprints/cosmetic marks.
