Yes you're a retard. Every description of fish eye lens are all variations of - 'A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image' - From wiki-nigger. Or this- 'It’s one of the most unique lenses out there for how it creates a spherical, warped perception of the frame.' They were not created for navigation you tard, they were 'based on how a fish would see an ultrawide hemispherical view from beneath the water ... Instead of producing images with straight lines of perspective'. So yes, they are using a lens that was designed to 'distort' the true image of how we would see something rather than use an actual panoramic lens if it were solely for navigation.
