WebWe look at what type of lens it is. This lens is a diverging lens. Diverging lenses always get contributed, always have a negative focal length that they contribute into this equation. So a negative 10 centimeters. That's … WebFocal length ( f) and field of view (FOV) of a lens are inversely proportional. For a standard rectilinear lens, FOV = 2 arctan x 2 f, where x is the width of the film. When a photographic lens is set to "infinity", its rear principal plane is separated from the sensor or film, which is then situated at the focal plane, by the lens's focal length. baikelu
