Stands for "Electronic focus".

So why bother including that in the lens identifications? Nearly all manufacturers make autofocusing lenses these days, but back in the late 80's virtually nobody did so it was a big deal. Smart marketing on Canon's part.

You don't really need to know what the acronyms stand for. All you need to know is EF lenses will work on all Canon digital cameras (and most of the newer film SLR cameras). And EF-S will not work on Canon's FF cameras.

Searching on Ebay yielded a lot of old school cameras mostly, if not all, 35mm.
