The newer digital canons have a smaller mirror set further back into the body and can take the EFS lenses. These are physically longer and so can use smaller rear lens elements and so are a bit cheaper to make. But they wont fit all cameras- my 30D takes them but my 10D won't.
HTH
so what happens if i use my old zoom lense, is it better/worse than before, do I need a longer lense for motor racing and if i do how do you tell whether its the old type or new. sorry for somany q's
