I am new to photography other than point and shoot so bear with me. My son is a baseball player and I want to take some pictures during the next few years before he gets out of high school of him playing baseball. My neighbor whose son also plays has a Canon XT DLSR and has taken some fairly nice shots of both of the boys, but he is a novice like me. I have been looking at the new XTi 10MP Canon and was wondering if the shutter speed would be capable of stopping a baseball in its tracks during a photo. If so, which lens would you recommend to accompany this camera. I understand that a f2.8 would probably be best if I am gong to take any pictures under the lights, but I don't think I can afford that. I guess I need something that will focus fairly quickly. Would the IS lens be what I need and would a 70-200mm lens be enough? Would you recommend another lens beside a Canon? As you can see for someone that is new to this, I am dealing with information overload. I have always wanted to get into photography more and really enjoy taking some sunset photos with my P&S. I am willing to put the time into this to learn it correctly, but want to make a purchase I can live with for about 5-10 years.
