Oh I certainly take your point about the if's and but's regarding going full-frame Keith although not too sure regarding the rest of your post. The best part (or sweet spot) of most lenses is in the 2/3 rds out from centre with deterioration towards the edge of the lens. For this reason a full-frame lens on a crop sensor camera is anything but a waste as the latter is essentially using all the sweet spot of the lens.
