OverviewThe smc PENTAX-DA* series has been developed through Pentax's unending pursuit of the ultimate image quality in digital photography. Bringing together its advanced optical technologies, including aspherical elements, special optical-glass elements and original lens coatings, Pentax has successfully developed a new interchangeable lens series that is superior to any existing lens series in terms of contrast, clarity and description, even at the edges.
The PENTAX-DA* zoom lenses come equipped with a new SDM System, which assures smoother, quieter autofocusing operation using a built-in supersonic motor. When mounted on a Pentax K10D or K100D Super Digital SLR camera body, the focus mode is automatically switched to SDM-assisted autofocusing. (The Pentax K10D firmware must be updated to take advantage of this automatic switching function.) When mounted on other Pentax digital SLR camera bodies, the conventional autofocus mode using a camera-mounted motor is selected.
