The Pentax SMCP-DA* 300mm f/4 ED (IF) SDM Lens is a high-quality telephoto lens that is designed for exclusive use with Pentax digital SLR cameras. It offers a focal length that is equivalent (in 35mm format) to 450mm. This wide coverage is ideal for a variety of telephoto applications, including portraiture, sports and scenery.
Pentax DA* (DA-Star) zoom lenses come equipped with the SDM System, which assures smoother, quieter auto-focusing operation by using a built-in supersonic motor. When mounted on the K10D digital SLR camera body, the focus mode is automatically switched to SDM-assisted auto-focusing. When mounted on older Pentax digital SLR camera bodies, the conventional autofocus mode using a camera-mounted motor is selected.
Like all Pentax lenses, this lens is treated with smc coating for maximum light transmission, sharp definition, and high contrast images. In addition, SP (Super Protective) coating made of a special fluoride compound has been applied to the front surface of the lens through the use of a unique evaporation process. As a result, the lens offers excellent water- and oil-repellent performance and makes for easier cleaning should the lens be accidentally smeared with fingerprints or cosmetics.
