News Photokina 2010 - Canon unveils a new lens extender designed for its L-series range of new super-telephoto lenses. Designed for photojournalists, nature and sports photographers who need to get close to distant and challenging subjects, the Canon Extender EF 1.4x III increases the focal length of a lens by a factor of 1.4x while still delivering superb image quality. To ensure the best possible image quality in all shooting conditions, the Canon Extender 1.4x also combines enhanced environmental protection, redesigned optics and improved data communication between lens and camera.

Canon Extender EF 1.4x for professional photographers
Allowing professional photographers to shoot distant subjects without having to carry a number of heavy lenses with them, the new extender ensures there is no compromise on image quality. The Canon Extender EF 1.4x III features seven lens elements in three groups, ensuring 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.
