Rated 4.5 out of 5 stars by 18 users at B&H Photo Video

"With it's low-light capability, wide field of view, and super close focusing distance (it does macro!) makes for a completely unique lens"

"I have found that I really love this lens for many purposes. (landscapes, people, milky way) I love the ability to have such shallow DOF with such a wide FOV"

"Certainly not the best lens for photographs, but for video at night, there is no other choice for me. I love this lens!"
