A recent Picture Postcard (Discovery and camera seeing) described how the view through a camera lens can show us something that cannot be seen with the naked eye. It wasn't describing how a long telephoto lens can bring distant objects closer, or how a macro lens can give us an extreme close-up view of something (these things are true, of course), but how the limited depth of field of a telephoto lens used with a wide open aperture can reveal an object in focus against an abstracted background or foreground.
