Excerpt: Great for instant panoramas. Just came back from photographing at a fabulous scenic overlook which was actually well over 180º. I was nearly able to get the entire view in one shot. With two shots, I could easily get the whole amazing view. Great color and sharpness. I also love the internal filter system. I had never seen anything like that.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Rugged, Strong Construction
Excerpt: I hesitated a long time over the price of a lens I thought would have limited use. Not so! I'll probably use it more than any other one lens. I try to take pictures of all my plantings a few times a year. With this lens I can get all the trees in an area into one picture. One very attractive picture. Everyone who sees what it can do has a project for it, from interiors to site surveys for Environmental Impact Reports.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Lightweight
Excerpt: I recently purchased the Fisheye 16mm f/2.8 lens from B&H Photo. Right out of the box, this lens took some very sharp awesome picture's. I took my first picture's near sunset on our beach in Hawaii. The sharpness and color was outstanding. I use a D800 and a D600 camera with this lens for fantastic photo's. The only watch out is to protect the lens from bumps, finger prints etc. as it has no protective filter. Any smudge on the lens will show up big time on the photo.
Pros: Consistent Output, Fast / accurate auto-focus, Fun, Lightweight, Sharp
Cons: Difficult to Clean, No protective filter, No Protective Lens
Summary: the rating would be like 4.75...wish the lens cap was more secure. overall the lens is nice/small/light. I stick it in my pocket or one of my small bags, when I pull it out the lens cap typically slips off. that's the only reason I didn't give it the full 5 stars .
