You can buy it with or without a lens, thou in your case buy it with the 18-55mm Kit Lens. don't listen to other people saying kit lens is rubbish and stuff, it not... it quite good actually and will do the job it needs for the time being. THEN later on when you've got use to using your Camera other than in Auto or P mode & discovered what Aperture, ISO, metering, exposer, white balance, stopping down ect means then consider about what lenses to go for depending on what kind of style of shooting you do. Also another thing to consider if you decide to get into this hobby is that it's not cheap if you want the best glass your going to have to pay for it. Here a good place to learn what all the above means, and how to use you 400D properly. http://web.canon.jp/imaging/enjoydslr/index.html
