So I am buying a Canon Rebel XT for my first camera, I am buying it from keh.com don't know if anyone has used it but someone I know recommended it to me. Anyways I was wondering what lense I should get for my first one? I want to shoot old buildings inside and out, landscapes, nature ect. it's my first lense so I am hoping it's fairly cheap. So if anyone could recommended me a lense and a place to buy it from and any other tips i'd appreciate it!
