Definition
A 'fisheye lens' is an extreme type of wide-angle lens with a very short focal length and a very wide field of view, typically around 180 degrees or more. It produces a highly distorted, circular or hemispherical image. Think of it as seeing the world through a bubble. π«§ It's often used for artistic or special effects. It creates a warped, surreal perspective. Its extreme distortion is its defining characteristic.
