Summary: I purcahsed this lens mainly to shoot the Aurora Borealis but find my self using it for many other applications. The lens is tack sharp and works well for shooting groups indoors. There are several software packages that allow you to flatten the image it you do not like the "fish eye" look.
Summary: What a great lens. it has been in production in it's current form since the mid 90's. my guess is that there has never been anything that needed to be changed about this lens. i've used it quite a bit now and it takes excellent photos. I have another fisheye that i use on my APS-C style cameras that is of a newer style, but this one works at least as well. Great deal on a used lens that never came out of the box.
Summary: been hesitant about purchasing a fisheye as it always seem more of a gimick than a tool. I have found it to be a great tool in the lens and creative arsenal. Very surprising results with landscapes as well as interesting results shooting golf courses and action.
Summary: I've been involved with Nikon equipment for a long time. My favorite lens is my 16 mm fisheye. I purchased it used in NYC back in the 80's. I even use my fisheye as a trade mark for some wedding shots for clients. Five of the photographs displayed were taken with my D700 & Nikkor 16 mm Fisheye.
Summary: I bought this one for traveling during my vacations. I needed a full range lens and quite light, just to carry one, and not several of my lenses. This lens is an excellent buy for the price, but much heavier than I thought. However it feels solid; very well built. Its AF is fast(not as fast to the PRO lenses) and sharp, except in dim light. I get sharp photographs throughout its full range.The bokeh is good but not as good as the Nikon 300mm f/4.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Rugged, Strong Construction
Summary: I buy all my lenses for film cameras, but when I was experimenting with portraits on my D200 this 16mm fisheye was performing miracles for me. Half of the time when I was shooting from an angle that prevented me from looking through the viewfinder, I was able to capture the scene I had in my head. Same goes for concert photography when you're right up front and in the band's face with your camera, this thing's focus performs admirably from any aperture.
