I'm looking to get a decent zoom lens for my father's D70. I was thinking about getting the Nikon 70-300mm f/4.5-5.6G ED-IF AF-S VR Zoom-Nikkor lens. It runs about $450 which is the price I'd like to stay in. Does anyone else have any other suggestions in that range? Is it even possible to get a decent lens at that price? Halp.
