Rated 4.5 out of 5 stars by 22 users at B&H Photo Video

"I wanted a really wide lens for landscaping photography, and this is definitely it! So far I cant find anything about it that I don't like."

"I like the size, very comfortable and I consider it now one of "always-in-my-bag" lenses."

"The one gripe I have is about the size of the filters...77mm. Oh, well, the results are worth it."
