A camera uses a positive lens to focus light from an object onto film. Unlike the eye, the camera lens has a fixed focal length, but the lens itself can be moved slightly to vary the image distance to the image on the film. A telephoto lens has a focal length of $200 \mathrm{~mm}$. By how much must the lens move to change from focusing on an object at infinity to an object at a distance of $30 \mathrm{~m}$ ?
