The basic facet of Nikon--that all lenses of the past are compatible with their current bodies (well, at least the full-frame ones and the one DX one with AI)--is a good one, but that also leaves us without a single film body that supports E lenses. I, for one, would like that capability. How about an F100E or F6E? That's all they need to do, put the E circuit on an otherwise unaltered body. It's not too awkward with the 300 because that gets used on maximum aperture a lot anyway but for anything you might want to stop down, it's a non-starter. With Canon, by contrast, you can take any of their film bodies and use any EF lens and it will work at any setting, the only limitation being the restriction of IS to cameras with multiple sensors for it.
