The fisheye lens allows for a 180 degree ultra-wide angle. It’s significant for its spherical view and distortion at the edges. The term “fisheye” was introduced by Physicist R. W. Wood in 1906. It refers to the perspective of a fish as it looks from inside a fish tank to the world. Wood predicted the fish would see a spherical view, where the middle is in focus and the edges curve.http://photography.tutsplus.com/articles/100-fantastic-photos-taken-with-a-fisheye-lens–photo-2367
The lens allows a subject to touch the lens and still maintain a clear, sharp focus. Since the lens is circular, light bends further rather than traveling straight through the lens to the sensor, resulting in a distorted image towards the edges.
I like this lens because it is a neat way to form abstract photos. It creates a completely unusual angle and perspective that other lenses can’t provide. Also, it creates memorable images that are hard to forget. Images that are interesting to the natural eye because they are set apart from normal photography.
