This is a DC series lens designed exclusively for use with Canon EOS DSLRs with APS-C size sensors.
The lens features FLD glass elements with performance equal to fluorite glass to compensate for color aberration.
The Super Multi-Layer Coating reduces flare and ghosting while superior peripheral brightness ensures high contrast images throughout the entire zoom range.
One hybrid aspherical lens and two glass mold elements give excellent correction for distortion and astigmatism.
It produces images with exaggerated perspective with its wide angle view.
The HSM (Hyper-Sonic Motor) ensures quiet and high speed AF as well as full-time manual focus capabilities.
