Five years ago, just before my Daughters wedding, I bought a Nikon D-100. I've\nloved the camera. But now I'm looking at these new D-40 and D-60 models. Besides\nthe nearly double megapixels, how much more am I getting if I bought one of the\nnew ones? And would I be able to use the lenses from the D-100 on the newer\nmodels? I spent ,000 on the D-100 and a lens five years ago. It almost hurts\nto see a camera with twice the resolution for one third the price. Thanks.
