Canon Extender EF 1.4X III
Overview
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.

| *1 | Data based on EOS models with exposures displayed in 1/2 stop increments. It varies slightly with the EOS-1v, EOS-1N, EOS-1 and EOS-3. |
| *2 | If the EF 70-200mm f/2.8L USM lens is attached to an EOS camera having multiple focusing points and an Extender is attached to the lens, only the center focusing point will be usable for AF. |
| *3 | The autofocusing range is from 0.8m/2.6ft. to infinity. |
| *4 | With the EOS-1D series, EOS-1v and EOS-3, AF is possible, but with the center focusing point only. |
| *5 | The Image Stabilizer does not operate with the following cameras: EOS 650, 620, 630/600, RT, 700, 750, 850, EOS-1, A2/A2E, 10s, Elan, Rebel/Rebel S, Rebel II/Rebel SII. |
