Sports shooting on a budget is tough.


Before you decide on lenses, you need to see what focal lengths you need, and how much light you're shooting in. If you can get close to a small field and can get your shot at like 100mm, your options are a lot greater than if you need a bigger zoom (like the 70-200 f/4, which is an excellent sports lens if you can get enough light to shoot at f/4).


Also, I'd suggest looking at a 40D...it's a good bit cheaper than the 50D and it has a higher frame rate that will be useful for sports...
