Need a wide-angle lens for my Nikon D80

Of course its wider, the 5D is full frame.

well yes, clearly that gives one 50% more viewing (when compared to the 1.5X crop on my digital body), but I have tried the 14-24mm Nikkor on a film body, so I guess I was commenting more on how much wider it was than even that. . .
