Built for the road

Everyone needs a lens like this in their kit: one that can weather the elements and get you crisp images wherever your subject takes you. The Pentax DA 18-55mm f/3.5-5.6 AL is just the lens you'll need when you're not sure what's next — a dramatic landscape, a child's face out on the playground — or a drenching rainstorm. 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.

While this lens is rugged, it has a sophisticated side as well. It's got a useful maximum aperture range of f/3.5-5.6, so it's ready for shooting in the great outdoors. Aspherical glass elements, plus special Pentax coatings make your images as sharp and artifact-free as they can be. The Quick-Shift focus system allows instant on-the-fly switching from auto to manual focus.
