The 18-55 is a great little lens, but if you mean close-ups as in macro photography (Nikon calls it micro) you'll probably want to keep saving for another lens. The 18-55 will do 1:3.2 which is actually one of the closest focusing non-micro lenses they make, but a true micro lens is 1:1 and will get a lot closer. If you're referring more to portraits, it can do it, but the lens doesn't have a very good ability to isolate the subject because of the small maximum aperture at 55mm (f/5.6, an f/2.8 will do a much better job, and an f/2 or bigger (smaller number) prime will do even better), and the bokeh (referring to how the out of focus area is rendered) is sorta ugly and distracting on the 18-55 vs other lenses. For a general purpose walkaround lens though, it's great and has surprisingly good image quality.
