Can you buy an adapter to use lenses from 35mm canon cameras on canon digital cameras?

I have a canon rebel slr and my grandfather has many lenses from his older canon (35mm). any help would be nice.

Canon lenses using the EF mount which was first used for film cameras do work directly on most Canon digital cameras (on 350D/Rebel XT I tested myself, using a lens from my older Canon Elan 7N film camera) without losing any abilities.

For older lenses that don’t usually fit, there are adapters that can help you fit the lens on a digital camera, however caveats include loss of resolution near the edges and loss of autofocus.
