A good walk around lens"I'll start and say right off the top, if you're looking for a great pro quality lens, this isn't it. Think of this as more an extended range kit lens. Don't get me wrong, I have seen some astounding images taken with this lens, but it's not up there with the pro quality lenses. That being said, the focal range is amazing on an APS-C sensor, the equivalent of about 27mm to 200mm, the build quality is better than a cheap zoom lens, it feels quite solid, and as a walk around lens, the focal length covers everything. Put it on any Pentax waterproof body and your camera is water sealed as long as you don't change lenses.
Pros - great focal range, compact size, waterproof when used with waterproof body. Great walk around lens.
Cons - inconsistent focusing and not as sharp as a pro quality lens at the edges, good center sharpness but not great. Usually comparable to a kit lens in IQ."
