One of these... (2.8 70-200mm) It really is all about the glass. A friend came over with his new D300 and that borrowed piece. His body was nicer than my D40 no doubt, but the images, aside from MP count, were not that different taken with the same glass. Sadly, in a 15x20 living room filled with furniture, it is tough to get a decent portrait shot with such a looong length. So I just ordered a 1.8 50mm for $40 off Fleabay.
