"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."

"This is the best lens for Pentax. The combination Pentax K20-D with this lens is better then Nikon or Canon."
