I'm new to the DSLR world. I'm thinking of getting the Canon XTI or 400d. Most people here say to get one without the kit and buy a separate lens. I have a total budget of $1000 for now. Probably could spend a couple of hundred more max if needed. Question: I'm interested in shooting portraits and groups of people indoors as well as outdoors in scenic places. What lens should I be looking for? Will my budget allow for more than one good lens?
