I have been using DSLR's for about 5 years. I started with the Canon t3i and when I wore it out I decided to move to Pentax with the K-5IIs. I chose this lens for it because it was both in my price range and had good reviews. That was the best choice I could have made! This is a top-notch lens, especially for the price. I had the long zoom kit lens for my Canon and it was loose and not near the build quality of this lens, nor was it as crystal clear. This lens allows the camera sensor to get the best information possible. I simply cannot say enough good things about it! The only annoyance, as others had noted, was that to zoom past 200mm you have to flip a switch, but its not the end of the world and you get used to it. I literally cried with joy at the images I could get with this. It is quick to focus, stays in the position I put it, is crystal clear, and oh the bokah! Depth of field is amazing, and I am convinced to get a shorter range Sigma for close-up work. You won't regret purchasing this lens. All the photos I am including were taken in low light on a cloudy day late in the afternoon or inside a building with no lights on. No flash was used, just the camera, lens and I.

Decent lens for a very acceptable price
By TechnoViking on Reviewed in the United States on September 4, 2013
Honestly, you get what you pay for. I'm not going to pretend this is the end-all of lenses or that it blew me out of the water. It's a very acceptable zoom lens for a very very decent price. I've been very impressed with the quality of Sigma's optics, and this is no exception. The lens is very clean, very crisp, and takes very nice photos. That said, the zoom is slow and noisy, and autofocus tends to just derp hardcore sometimes. When focusing on a very close or very far object, it will often zoom all the way in and out a few times attempting to focus on the object. These are all things I'm willing to accept for the price I paid. Pictures in the 80-150mm range come out very crisp and the lens is decently fast. 150-300mm definitely will require a tripod or other sturdy object unless it's very bright and you're shooting at 800-1600 ISO. It's good introductory lens and a great add-on to any Pentax K-5 K-7 or K-30 kit. All the negatives aside, I've taken some fantastic photos with this. It's done very well for daytime shoots of wildlife and I've gotten many "national geographic" type photos with it. The bottom line: If you wan't to be blown away with ultra-crisp photos at low ISO at 300mm, this lens is not for you. If you want a decent zoom lens that you will use with a tripod and mostly for daytime-use at a low low price, get this lens!
