You might also see reference of aspherical lens components. Lenses are generally areas of a ball. Lenses must focus light into the flat aeroplane of a movie or a digital sensing unit while our eyes must concentrate on the back of our eye, which is additionally spherical. In order for light to be concentrated on to the level aeroplane of film or a digital sensing unit lens aspects are made aspherical to compensate for the diffraction of light via the lens. When it comes to camera lenses there is a difference between lenses boosted for use on digital video cameras and also those that are not.
