If you buy a cheap 50mm for your camera, it'll work from entry level to pro body. I only use Canon since I got the 350d, but since then I steadily upgraded my gear, lenses and bodies. I never was at a point where a lens was not compatible with my camera. At one point of course you can choose to sell a lens to get a better one, but that doesn't mean all of your gear has become useless. So I don't get where you think this is a fallacy -- it actually is one of the strongest selling points for DSLRs, image quality aside.
