Designed for exclusive use with Pentax digital SLR cameras, the Pentax DA series 50-135mm telephoto zoom lens makes it easy to capture close-in sports shots or intimate wildlife photography. The lens is distinguished by its aspherical elements, special optical-glass elements, and original glass coatings, which help produce a high contrast, unmatched clarity, and edge-to-edge sharpness.

And users will love the new SDM system, which produces smoother, quieter autofocusing using a built-in supersonic motor.
