Hello, I'm completely new here and was hoping to call on you all for some advice for a total novice. I have a Canon Rebel T2i that I got as a present and I'm looking to do some sports photography with it. My question is I'm looking into purchasing a 70-200 2.8 to take football pictures here in North Carolina. What, if any, are the problems I will face using it? I have seen the FPS should be at least 4, and my T2i is rated for about 3.7. Will it be possible to get the crisp shots I'm looking for with my old T2i or will I be forced to upgrade in order to get the shots I'm looking for? Any help would be tremendously appreciated. Thank you from a total and complete novice.
