TO UPGRADE OR NOT UPGRADE - here is what Thom Hogan, the Nikon guru, had to say. "The answer is quite simple: you shouldn't upgrade unless you've exhausted an important ability of your current camera and know that the new one will clearly surpass it in that ability. As we get deeper and deeper into the digital era, each generation of new cameras tends to produce smaller and smaller improvements, or improvements that are difficult to distinguish in "normal" prints and use." That sounds like good advice to me. It is so easy to get seduced by the marketing (and almost all photography magazines today are 90% (including the articles) marketing).
