Hi all, looking for some specific lens suggestions.... I am looking to get either a T2i or T3i. (18 mp.) I know I can get a kit that comes with a lens, but I know those aren't usually the greatest. Any suggestions on a good quality lens that will make the most of the camera if I buy the body and lens separately??? I will mostly be shooting portraits. Specific model #s would be great. I have a baby at home and not a lot of time to research. Thanks!
