What are canon EF-S lenses? What is the difference between EF-S & EF lenses?
Are EF-S optimized for digital cameras, to take into account the 1.6x
conversion factor on small-framed sensors?
Yes. EF-S lenses are optimized for digital cameras. They
are mechanically set up so that they are difficult or
impossible to mount on full-frame cameras.
You seem to forget there are Full Frame Digital cameras.
The reason they are made not to mount on FF Canon bodies is they are a
compromise for small sensors.
Sorry. Badly written. See my last sentence above.
