CAN ANYONE HELP ME PLEASE!!!!! I'm in the market to buy a 20D Canon to take proffetional wedding pictures. Can anyone give me some advice as to which lens I should purchase? Would the 17-85mm wide angle lens be good? why or why not? Or should I go with a 18-55mm lens? why or why not? Or any other recomondations. I will be taking pictures inside and outside. If anyone can take the time to inform me I would so greatly appreciate it. Thanks Amber
