I'm getting my first camera(rebel xt), used, (friend of a friend thing,) and it'll come with the 18-55mm kit lens. Will this do what I need, or will I have to buy a new lens or two? I want to be able to photograph my artwork - I paint a lot, mostly canvases sized 16"x20" to 22"x28", but also larger occasionally. I want to be to shoot nice, accurate photos of my artwork. I also want to experiment with photography of course, and work on composition and such. I find myself taking pictures of things anywhere from 5-10-50 feet away when I am out with my boring point and shoot. So could the 18-55mm do this well?
