(Edited by moderator. Please use punctuation and, you know, sentences.) I just got a Canon EOS Rebel T2. I've never used film before.I also got a 75-300mm lens. I'm taking hockey pictures tomorrow and I've been told not to use manual focus and to use AI Servo AF. But I can't figure out how to put my camera in that mode. I followed all the instructions but it's not working. I was also told to change the aperture to 1600 but thats not changing either. Any advice will help. Thanks.
