Canon Extender EF 2X III is designed for select Canon L-series telephoto lenses to improve shooting performance. This extender is EF mount compatible. It is the perfect device for extending the focal length of the lens by 2x.

Our Take on the Canon Extender EF 2X III:

Canon's engineering department has gone to great lengths to provide the best image quality in all shooting conditions. This device combines upgraded optics and improved communication between lens mechanisms and camera electronics. As this is a focal length extender, it is perfect for all distant photography applications such as photojournalism, nature, wildlife, sports, and landscape photography.

Canon Extender EF 2X III not only improves camera performance but also obviates the need to carry heavy, high-aperture lenses. It weighs only 325g, making it perfect for traveling photographers. The extender comes with nine optical elements in five groups, which guarantee exquisite optical performance. Further, these elements possess a Super Spectra coating that reduces ghosting and flare. Additionally, the front and the rear elements also possess the new Fluorine Coating that eliminates smudging, marks, water spots, or fingerprints.

The extender comes with a carefully positioned lens release mechanism that makes it quick and easy to mount the extenders. This feature not only reduces the setup time but also adds to the security of your expensive equipment. Further, the extender possesses exceptional build quality that is resistant to dust and water, making it even better for traveling photographers who don't have to worry about destroying their equipment in inclement weather conditions.
