Rated 5 out of 5 stars by 9 users at B&H Photo Video

"I shoot a lot of interiors of homes, and this was just the perfect lens to add to my arsenal. Great depth of field, nice and wide, and hardly any distortion."

"Fun lens for architecture/interior design photography and other cool compositions where you get plenty of light. "

"The only downside is it a bit heavy and in some situation you may ned to use a tripod."
