Summary: This lens is good for this price especialy its a wr and also its very small. Some people say its sharp at f8 - f11 but mine sometime is little soft. i was gonna return but i found the sweet spot at f4-5.6 and desided to just kept it. The quality is very good also and it focus really fast outdoor and indoor. I recommend this lens to anyone who's looking for small light zoom lens and to pair with their wr camera.
Summary: I'm a novice when it comes to cameras but since I got the Pentax K-30 I love taking pictures, My husband then got me the Da 50-200mm lens. It makes a big difference. I live in the county and can now take pictures of the wildlife with no problem of scaring them off. I'm so happy with what I can do so far I'm taking a photo class to see how much better I can really get. Having so much fun!
Summary: Fantastic lens! I have used this lens in dirt, dust, rain, and snow. It performs flawlessly. It is a fanstastic lens at this price-point. This lens has taken a beating. It has been dropped on the concrete and in the dirt...not an issue. Yes, it has flaws at max zoom as one would expect for a sub $200 lens, but in my humble opinion, its a great value and takes good pictures considering one can have it in inclement conditions!
Summary: This inexpensive zoom is decently sharp at all focal lengths. IQ is very good for such a budget glass. Distortion is negligible. When I MF with it I have a feeling that I might gladly use more focus throw. But it's OK because it's primarily AF lens. Quick shift works flawlessly. Focus Camera did great job - superb CS and prompt delivery. Thank you.
Summary: I bought this lens for the Pentax K200D. It's great for picking up where the 18mm-50mm standard lens leaves off. Plus this addition has made the camera complete weather resistant, which is great.
