Rated 4.5 out of 5 stars by 7 users at B&H Photo Video

"I have been very satisfied: this lens is absolutely great for low light, or portraiture, requiring large apertures. I shoot with a Pentax k-x, non full-frame, and so the focal length is closer to 85 mm, perfect for portraits."

"First off it's a solid lens, a bit heavy but it takes a beating. Fast focus and quiet. I use it with k20 and I am very happy with the results. A must for low light photography."

"The lens focused approximately 1/2 inch in front of the object (nearly too much for the camera - K20D - to compensate). Now it's on the way to SIGMA - and I expect them to fix it."
