Fish eye Lenses Explained In Plain English In Less Than 10 Minutes

A fisheye lens is an ultra-wide camera lens that typically provides a 180-degree field of view. A fisheye lens can be either circular or full frame, with the circular type taking a circular image with a black surround and the full frame fisheye lens taking a distorted image that fills the frame. Fisheye lenses produce alternative dramatic distorted images.
