"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."

"I love the lens in almost all ways. It's sharp, fast focusing, needs very little light in F1.4 and the quick shift to manual focus is really OK to have."
