Canon Extender EF 1.4x III

The Canon Extender EF 1.4x III extends a Canon EF super telephoto lens focal length by a factor of 1.4x, incorporating excellent optical performance with minimal chromatic aberration. It features a built-in microcomputer for seamless communication between camera body, lens and extender, as well as precise lens placement and coatings to minimize ghosting and flare. The Fluorine coating keeps soiling, smears, and fingerprints to a minimum, and the housing is rugged, dustproof and water resistant.

*NOTE: When Extender EF 1.4x III is attached, the lens maximum aperture will be reduced by 1 stop. Refer to your camera and lens instruction booklets for any AF compatibility limitations due to reduced max aperture.
