Canon EF & EF-S lenses
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? |

Not just optimized, but there's a mechanical difference such that EF-S can't be mounted on EF-only bodies (at least not without modifying the lens mount). EF lenses can be used on both EF & EF-S mount cameras. Mark |

It may be also that the EF-S is optimized for the manufacturer, the optics are cheaper to build for smaller "negative". I am not particularly pleased of the fact that Canon has different lens/bodytypes that can't be used mixed. |

EF-S lenses can be used only on bodies with APS-C size sensor. If you want maximum compatibility, just don't buy the EF-S lenses. The L lenses are all EF mount, so you won't be sacrificing any quality. -- Måns Rullgård |

EF-S lenses can be used only on bodies with APS-C size sensor. Not quite. The 10D, D60, & D30 can't take EF-S lenses. In a sense you're right, all Canon's current APS-C DSLR bodies can accept EF-S.
