The 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.* When mounted on other PENTAX digital SLR camera bodies, the conventional autofocus mode using a camera-mounted motor is selected. * The PENTAX K10D firmware must be updated to take advantage of this automatic switching function
