Designed to extend a lens's focal length by a factor of 2x, the redesigned Canon Extender EF 2x III delivers optical performance on par with the finest Canon super telephoto lenses. It features a built-in microcomputer for seamless communication among camera body, lens and extender, features careful lens placement and coatings to minimize ghosting, flare and chromatic aberration, and even has a fluorine coating that keeps soiling, smears and fingerprints to a minimum. Extender EF 2x III meets necessary standards in terms of rugged, dustproof and water-resistant construction, and should be in every professional's camera bag.
Focal length extension for super-telephoto lenses
The Extender EF 2x III is specially designed to work in conjunction with L-series IS super-telephoto lenses, extending their focal length by a factor of 2x. The extender's design ensures there is no loss of lens performance or image quality.
Improved anti-reflection materials inside the lens-barrel and a coating around the outer edges of the lens elements reduce flare. Construction is resistant to dust and water, helping to maintain images quality.
Improved communication between lens and cameraProduct Highlights
A built in microprocessor provides accurate transfer of data from between the lens and camera delivering an improved performance in AF and metering.
