No difference, it just means your camera will accept EF-S lenses as well as Ef ones but when an EF lens is fitted it behaves exactly the same way as if it was fitted on an Ef only camera except most Ef only cameras are full frame so no cropping of the image takes place but that is a different subject. On your camera the view you get is as if you had a 160mm lens on a full frame camera so you get an apparent magnification with your camera.
