I have a Canon EOS Rebel ti1. I only have the original lens it came with. I am not savy when it comes to lenses. I would like to have more zoom and I don't know what to buy. I also own a Canon S95 but zoom on that is limited too. Plus, I would like to take the bigger camera on my next trip. I would like to know what lens is your favorite on a digitalSLR for disney photos. Duh. Please help!
