Links to VEYLDF. Victorian Early Years Learning and Development Framework (2016) Camera lens focal lengths are usually specified in millimetres (mm), but some older lenses are marked in centimetres (cm) or inches. Focal length (f) and field of view (FOV) of a lens are inversely proportional. For a standard rectilinear lens, FOV = 2 arctan x/2f, where x is the width of the film. When a photographic lens is set to "infinity", its rear principal plane is separated …
