What is FOV (Field of View) Optical Basics

WebIn photography, angle of view(AOV)[3]describes the angularextent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view. It is important to distinguish the angle of view from the angle of coverage, which describes the angle range that a lens can image.
