I just bought a Canon EOS rebel XS two days ago. The autofocus will not work, the only things that will show up (not blurry) are about 10 feet away. This really hurts me because number one: i am not a very experienced photographer so i have NO idea what is going on, and number two, to the two things i take pictures of the most are flowers, and birds. and since it will not autofocus, i can't take pictures of either of those. Yes, i have switched the switch on the lens from manual focus to autofocus, it still doesn't work. the only thing that i have doe that could have effected it are i took the lens off so i could take it to a friends house, and i was playing with the f-stop a bit. Please help me, i need an answer by Sunday, i am leaving on a road trip to Seattle and i really want to have my camera up and ready by then. thanks.
