I know this has been talked about before probably, but I wanted to give fresh opinions. I am going to Disney World in September with my husband and 3 year old. I have a Canon T1i with the kit lens (18-55) and a 50 mm/F1.8. I was considering renting a better lens to take. I just cant decide which one to rent. I will mainly want good pictures of my daughter up close and on rides. It would be nice to get some good scenery pictures, but that isnt my top priority. I want something that will take better pictures than my kit lens, but not extremely heavy. I was considering the Canon 18-135mm but wasn't sure if it was heavy. Any advice or suggestions on what lens to rent? Thanks!
