Spec: Description: On most lenses, the manufacturers provide a focusing mechanism that extends only a few millimetres, partly to keep down costs and partly to restrict the lens to extensions for which its optics are optimised. To provide additional extension, one or more extension tubes can be added between the camera and the lens, to make the lens focus at closer distances and therefore produce higher magnification.
