Canon EF 1.4X III Telephoto Lens Extender - Compatible with EF Lenses for DSLR Cameras | Enhance Zoom for Wildlife & Sports Photography

Canon Extender EF 1.4X III extends lenses focal length by a factor of 1.4x. The Canon Extender EF 1.4X III incorporates phenomenal optical performance with minimal chromatic aberration and is the perfect complement to many of Canon's 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 new Fluorine coating that keeps soiling, smears, and fingerprints to a minimum. An integral part of many professional systems, Canon Extender EF 1.4X III maintains high standards not only optically, but also in terms of rugged, dustproof, and water-resistant construction. This lens is only compatible with fixed focal length L-series lenses 135mm and over, as well as the EF 70-200/2.8L, EF 70-200/2.8L IS, EF 70-200/4L, and EF 100-400/4.5-5.6L.
