1. fisheye lens

   A fisheye lens is a type of ultra-wide-angle lens that produces strong visual distortion to create a wide panoramic or hemispherical image. Its design uses a particular mapping to intentionally distort the image in a way that mimics the way fish would see under the water. The lens achieves extremely wide angles of view by forgoing a rectilinear image, opting instead for a special mapping, which gives images a characteristic convex non-rectilinear appearance.

1. Fisheye lens

   A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. Fisheye lenses achieve extremely wide angles of view by forgoing producing images with straight lines of perspective, opting instead for a special mapping, which gives images a characteristic convex non-rectilinear appearance. The term fisheye was coined in 1906 by American physicist and inventor Robert W. Wood based on how a fish would see an ultra-wide hemispherical view from beneath the water. Their first practical use was in the 1920s for use in meteorology to study cloud formation giving them the name "whole-sky lenses". The angle of view of a fisheye lens is usually between 100 and 180 degrees while the focal lengths depend on the film format they are designed for. Mass-produced fisheye lenses for photography first appeared in the early 1960s and are generally used for their unique, distorted appearance. For the popular 35 mm film format, typical focal lengths of fisheye lenses are between 8 mm and 10 mm for circular images, and 15–16 mm for full-frame images. For digital cameras using smaller electronic imagers such as 1/4" and 1/3" format CCD or CMOS sensors, the focal length of "miniature" fisheye lenses can be as short as 1 to 2mm.
