"WebFisheye Lenses with 180°+ Field of View do not always provide 180° FoV if used with a smaller sensor. For example, a Fisheye with Full Coverage can provide much smaller fields of view such as 160° Diagonal, where they act as a "Wide Angle" Lens. The reason for this is the "Fisheye Fill Factor" which has six different general categories. " - Fisheye fov
