Manufacturer’s Description
The Pentax DA * 50-135mm F2.8 ED telephoto zoom lens is designed for exclusive use with Pentax digital SLR cameras, delivering the highest level of ultimate optical image quality. With spherical elements, special optical-glass elements and original lens coatings, this lens is superior in terms of contrast, clarity and edge-to-edge sharpness. The 50-135mm features tightly sealed, weather-resistant and dust-resistant construction to enhance durability for use in rain or dusty conditions. A new SDM system has been incorporated for smoother, quieter autofocusing operation using a built-in supersonic motor. It also features the Pentax-original Quick-Shift Focus System for instant switching to manual-focus operation and Pentax-original SP coating to repel dust, water and grease.
