Not sure if EF-S lenses will vignette. Never shaved the back of one and put it into my APS cameras!
It's not like the DX/FX lens paradigm of Nikon where lenses are specifically made for a particular format. In the Canon world, there used to be the FD mount, the EF mount and the newer lightweight/cheap EF-S mount. The EF-S mount is typically for kit lenses which are made of plastic, and very lightweight. Having said that, there's one or two which get rave reviews -- particularly the image stabilised ones. But, no, there's no DX/FX thing in the Canon world.
