Extender 1.4x III Focal length extension for super-telephoto lenses

\nCanon Extender 1.4 x High-quality construction
\nImproved 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.\n

\nCanon 1.4 x Extender Improved communication between lens and camera
\nA built in microprocessor provides accurate transfer of data from between the lens and camera delivering an improved performance in AF and metering. Compatible with L-Series telephoto and telephoto zoom lenses\nThe Extender EF 1.4x III is compatible with most telephoto and telephoto zoom lenses within Canon’s flagship professional L-series range, extending the focal length while only reducing the effective aperture of the lens by one stop.\n

Purpose built for outstanding image quality, this lens renders crisp detail, faithful colour and smooth background blur. Special glass elements and advanced coatings work to minimise aberrations, flare and ghosting for clean, high contrast results.

A bright aperture and responsive autofocus help you track and isolate subjects with confidence, while robust construction and (on supported models) optical stabilisation provide reliability for travel, events and professional assignments.
