Hi! I've got a Canon 7D, and a friend asked me to shoot her family this weekend, so I will need to rent a lens. It's in her parents house, and I'm assuming there's going to be a minimum of 10 people, probably more. I'd like a lens that will give a blurred bgd, sharp focus on the people, but can take in a larger amount of people. Being it's a rental, skies the limit on which lens I can get, as I don't have to shell out too much for it. Thanks for suggestions in advance 
Jodi
