What are extension tubes...?
Essentially hollow metal tubes which fit between your lens and the camera body to allow the lens to focus very closely. They're a little more annoying to use, and the less expensive ones won't allow you to do auto-focus/auto-metering (not a huge deal in macro anyway), but they do have the advantage of not having any glass in them, so can't distort the image.
