The Canon Extender EF 2X III is designed for use with select Canon EF mount L-series telephoto lenses, effectively doubling the focal length while maintaining outstanding image quality. Ideal for photographers who need to get closer to distant subjects—such as wildlife, nature, sports, and photojournalists—the extender offers a practical solution without the need to carry bulky, long telephoto lenses. It is compatible with a wide range of Canon L-series lenses, including fixed focal length lenses of 135mm and longer, as well as several versions of the EF 70-200mm and EF 100-400mm lenses.

The extender uses nine optical elements arranged in five groups, providing improved performance. Canon’s Super Spectra coatings on all elements help to reduce flare and ghosting, ensuring clearer, sharper images with accurate color reproduction. Furthermore, the Fluorine Coating on both the front and rear elements minimizes the impact of dust, fingerprints, and watermarks, making the lens easier to clean.

For fast and reliable performance, the integrated processor in the extender ensures seamless communication between the lens and camera, enabling autofocus, metering, and ID data transfer. It helps to capture well-exposed and balanced images, even with fast-moving subjects. As a result, photographers can expect optimal AF accuracy when shooting action scenes. Although the extender reduces the effective maximum aperture by two stops, it does not compromise on focus or image clarity.

Designed for professional use, the Canon Extender EF 2X III is weather-sealed against dust and moisture, making it ideal for photographers working in challenging environments, from wildlife expeditions to sports events in harsh weather.
