In a 35 mm single lens reflex camera (slr) the distance from the lens to the film is varied in order to focus on objects at varying distances. over what range must a lens of 45 mm focal length vary if the camera is to be able to focus on objects ranging in distance from infinity down to 1.4 m from the camera?
