Extender EF 1.4x III

Extending a lenses focal length by a factor of 1.4x, Extender EF 1.4X III incorporates phenomenal optical performance with minimal chromatic aberration and is a perfect complement to many of Canon super telephoto lenses. It features a built-in microcomputer for seamless communication among camera body, lens and extender; features careful lens placement and coatings to minimize ghosting and flare and even has a new Fluorine coating that keeps soiling, smears and fingerprints to a minimum. An integral part of many professional systems, Extender EF 1.4X III maintains high standards not only optically, but also in terms of rugged, dustproof and water resistant construction.

*When Extender EF 1.4x III is attached, the lens maximum aperture will be reduced by 1 stop. Refer to the camera and lens instruction booklets to see if there are any AF compatibility limitations due to the reduced max aperture.
