Our take on the Pentax DA 18-135mm f/3.5-5.6 Lens

by Woody Sherman

Master of reunion ceremonies

Here's a lens that will take you from the reunion group shot to a tight shot of the family water-skier's face — taken amidst the spray at the back of the boat. The zoom range is an impressive 7.5X, so you'll have options no matter the venue. With weather-resistant, dust-resistant construction, this lens is the perfect companion to the Pentax K-5 weather-resistant digital SLR. Between the two, you'll have a combo that's built for bringing home the elusive shot under challenging circumstances.

Plus, this lens isn't just rugged — it's got optical talents as well. Extra-low dispersion and aspherical glass elements, plus special Pentax coatings, make your images as sharp and artifact-free as they can be. And the DC (direct current) motor autofocus is quiet, responsive, and accurate.
