Canon Extender EF 2X III

The Canon EF 2X Extender III is designed for select Canon EF L-series telephoto lenses. It doubles the focal length of a lens while delivering exceptional image quality. To ensure the best possible image quality in all shooting conditions, it combines redesigned optics, improved data communication between lens and camera, and enhanced environmental protection. It is ideal for photojournalists and wildlife, nature, and sports photographers who need to get close to distant and difficult subjects, and reduces the need to carry heavy telephoto lenses.
