Designed for exclusive use with Pentax digital SLR cameras, the Pentax DA* 16-50mm f/2.8 wide-angle zoom lens is a terrific choice for landscapes, portraiture, and just about any other application. The lens features a tightly sealed, weather-resistant and dust-resistant construction to enhance durability in rainy or dusty conditions. The lens's three aspherical elements and two special optical glass elements, meanwhile, help compensate for chromatic and spherical aberration, producing images with superior contrast, clarity, and edge-to-edge sharpness. And thanks to the lens's Pentax-original Quick-Shift Focus System, you can easily and instantly switch from autofocus to manual focus.
