Excerpt: Came with my K-7. Was very disappointed in the sharpness of images. Thought it was a problem with the camera until I bought a Pentax-A 50mm f1.7 prime lens off craigslist. Wow, the difference is unbelievable!!!! The 18-55 goes in the junk drawer. Shame on Pentax for putting such a crummy lens on such a nice camera.
