Rated 4.5 out of 5 stars by 3 users at B&H Photo Video

"Great lens for outdoor and even interior/architecture. This is a really fun lens especially on portrait."

"I have been shooting sport photos for a while now and was looking for something new to spice up the images. I wasn't sure how I could use the fisheye but now I have had a chance to use it... wow. I can get some excellent images from a perspective I have never used before. I love this lens."

"It has taken me a bit of practice and it has been worth every second."
