Communication Between Lens & Camera

The Extender EF 1.4X III from Canon is designed for select Canon EF mount L-series telephoto lenses. It 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 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 challenging subjects and it reduces the need to carry heavy telephoto lenses.

The Extender EF 1.4X III features seven optical elements in three groups and all optical elements have Canons Super Spectra coating to reduce ghosting and flare. 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 balanced well-exposed images. When combined with the latest range of premium Canon L-series lenses these extenders enable AF accuracy even when capturing moving subjects. When attached the 1.4x extender reduces the effective maximum aperture by 1 stop.

A carefully positioned lens release mechanism also makes it easy to mount the extenders quickly reducing the time that the camera and lens are exposed to the environment. The extenders offer the exceptional build-quality expected from Canons professional products and are resistant to both dust and water allowing photographers to use them in extreme shooting conditions.
