Fisheye Lenses

Fisheye lenses get their name from their ability to see an extremely wide angle of view (like the eye of a fish.)

The top image is a typical fisheye view. The lens used was a Nikon 10.5mm f2.8 DX which offers a 180 degree angle of view from side to side. The fisheye lens will make objects appear slightly unnatural due to its extremely wide view and often straight lines will look curved (see the intersection of the walls and the ceiling.)

But with Nikon's Capture software, the images can be rectilinearly corrected so that the image appears more normal (see the bottom picture.) This will lose some of the extreme wideness of view, but it's still much wider than your average wide angle lens.

Fisheye lenses are great for taking images of an entire room. There's nothing quite like a fisheye lens.
