The Canon Extender EF 2X III is specifically designed for Canon's L-series new range of super telephoto-lenses. It is most suitable for photojournalists, sports and nature photographers who seek to get closer to their often challenging subjects. The extender can increase the focal length of the Canon lens by a factor of 2x, while still producing excellent image quality.
The Canon Extender EF 2X III is the perfect solution for photographers who want to shoot distant subjects but don't want to carry too many lenses. The use of the extender will not compromise the quality of the image.
The extender sports nine elements in five groups, all aimed to improve optical performance. The optical elements all sport Canon's Super Spectra coating, which is very effective in reducing flare and ghost, as well as to minimize post-processing requirements. As for the new Fluorine coating, which is present on the front and rear part of the extender, it allows for an easier cleaning up of marks or finger spots. It is certainly much better than the standard coatings.
The Canon Extender EF 2X III has a built-in processor that can provide a more accurate transfer of imaging data between the camera and the lens. As for the new design of the extender, it's aimed to complement the professional look of L-series lenses and to match their appearance.
