SOME EF-S lenses can be used on FF bodies, such as the Sigma 10-20 on a 5D2. It's not an impossible thing, but I doubt Canon is ready for FF compact cameras yet.As far as I know, Sigma doesn't make EF-S lenses, only canon does. Sure, you'd have problem with heavy vignetting etc on 3rd party lenses made specifically for crop lenses, but they can all be physically used on full frame cameras.
