To my knowledge, there were NO manual lenses for EOS mount. EOS = electronic optical system. Canon EF lens mount - Wikipedia, the free encyclopedia
EF-S were EOS (EF mount) lenses designated for APS sized sensor DSLRs.
Equivalent in Nikon circles would be "DX" lenses - their image circle won't cover a 35mm film frame.
