Extender EF 2x Mk III
introduced December 2010
Designed for photojournalists, nature and sports photographers who need to get close to distant and challenging subjects, the Extender EF 2x III increases the focal length of a lens by a factor of 2x while still delivering superb image quality. To ensure the best possible image quality in all shooting conditions, it also combines enhanced environmental protection, redesigned optics and improved data communication between lens and camera.
Canon professional image quality
Allowing professional photographers to shoot distant subjects without having to carry a number of heavy lenses with them, this new Extender ensures there is no compromise on image quality. The Extender EF 2x III features 9 lens elements in 5 groups, giving improved optical performance. All optical elements use Canon’s Super Spectra coating, reducing ghosting and flare to minimise post-processing requirements. A new Fluorine Coating on the front and rear elements makes marks, such as spots left by water or fingerprints, much easier to clean than standard coatings.
To facilitate the accurate transfer of imaging data between the lens and camera body, the Extender features an integrated processor which ensures all focusing, metering and ID information is available – allowing the photographer to capture crisp, well-exposed images. When combined with the latest range of premium Canon L-series lenses, the Extender enables higher AF accuracy compared to previous generations, ensuring professionals achieve perfectly sharp shots, even when capturing moving subjects.
Redesigned for high performance
The Extender EF 2x III has been designed to complement the latest range of L-series lenses, matching their appearance and offering a visible differentiation from previous models. A carefully positioned lens release mechanism also makes it easy to mount the Extender quickly, reducing the time that the camera and lens are exposed to the environment. The Extender offers the exceptional build-quality expected from Canon’s professional products, and is resistant to both dust and water, allowing photographers to use them in extreme shooting conditions.
For convenient transport, the 325g Extender EF 2x III is supplied with a soft case (LP811) and Extender Cap EII.
