Summary: No matter where my wife and I go with our cameras this lens is always with us. It is just too versatile to stay at home. A must have for any Pentax owner, especially if you plan on extreme conditions.
Summary: I have both Canon and Pentax cameras. Over the past year I've bought maybe 7 different lenses, but for some reason I was always left somewhat unhappy with them. I love the build of primes, but I love the convenience of zooms, but %100 of the time zooms disappoint in build quality and small max...
Summary: This lens is incredible in all regards--when you are lucky enough to have one which functions as it should. Before you read further, I'd recommend three things if you are reasonably sure you will purchase: 1.) Do NOT buy this lens used! 2.
Excerpt: This lens is truly outstanding! The optics are amazing (sharpness, contrast, colors...), as good as my prime limited lens. The quality of built is superb. I even like the size and weight of this lens that balances out well with the body of my camera (K5).
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Rugged, Strong Construction
Summary: I have had this lens for almost 2 years now, and not a problem with it. It takes beautiful pictures, sharp and clear. Sweet spot for this lens is between F5 and F9. Worth every penny spent. I have it paired to a K-30, and I love this setup for landscape and portrait photography.
