                	 The Canon EF 2x Extender III increases the focal length of a lens by a factor of 2x while still delivering superb image quality. This teleconverter contains a built-in microcomputer for seamless communication among camera body  lens and extender. It also features careful lens placement and coatings to minimize ghosting and flare  and even has a Fluorine coating that keeps soiling  smears and fingerprints to a minimum. An integral part of many professional systems  this extender maintains high standards not only optically  but also in terms of rugged  dustproof and water resistant construction.
