Canon EF 1.4X III تقویت کننده تله فوتو برای لنزهای فوق العاده تله Canon (تجدید شده)

Extending a lenses focal length by a factor of 1.4x, the Canon 1.4x EF Extender III (Teleconverter) 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.
