Amazon.com Product Description
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. The lens also boasts a tightly sealed weather- and dust-resistant housing that stands up to rainy or dusty conditions. And users will love the new SDM system, which produces smoother, quieter autofocusing using a built-in supersonic motor. Other details include a Pentax-original Quick-Shift Focus System that switches instantly to manual-focus operation, a Pentax SP coating that protects the exposed lens elements, and a focal length equivalent to 76.5-207mm in the 35mm format.

Customer Reviews

One of the BEST pentax lenses
This is perhaps one of the best Pentax lenses ever made. If you need this focal range just go for it! The sharpness is unparalleled! Weather sealing is also nice. I use this for pro photography and photojournalism.

Excellent. One of the best!
I'm happy to add my voice to multiple A+ reviews for this great lens.
It's sharp, beautiful colors, bokeha, fast, silent. If you can afford it - it's no brainer.

amazing lens...
This lens is amazingly clear, focuses quietly and quickly, is easy to handle and has beautiful bokeh. I've shot one wedding and two on-location portrait sessions with this lens so far and would recommend it heartily to anyone looking for that perfect middle-ground portrait lens. 50-135 is just right to find that portrait look without being too close or too far away.

I'm still amazed at the clarity of the lens every time I look at these images. I'm using a K20D but have put the lens on my back-up Samsung GX-10 with the same results.

Buy it, you won't regret it.
