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

"This is a great lens to travel lightly with and always stays in my "to go" bag when heading out the door."

"It focusses quickly and sharply. I am amazed by the night-time shots. Very sharp and fast focus!"

"The only down side is it lacks the distance information for Sony's flash system."
