Canon Extender EF 1.4X III Teleconverter for EF L-Series Lenses (4409B002) + 64GB Extreme PRO UHS-I SDXC Memory Card — Canon USA Authorized

Canon USA Authorized. Package includes: Canon Extender EF 1.4X III and a 64GB Extreme PRO UHS-I SDXC Memory Card. The Extender EF 1.4X III multiplies the focal length of compatible Canon EF L-series telephoto lenses by 1.4x, giving you additional reach for sports, wildlife, and nature photography while only decreasing the maximum aperture by one stop.

Its optical construction uses seven elements arranged in three groups and features Canon’s Super Spectra coating to reduce flare and ghosting while maintaining strong contrast and accurate color rendition. Front and rear elements are finished with a Fluorine Coating to resist smudges, water, and fingerprints for easier cleaning and upkeep.

An onboard processor preserves full communication between camera and lens, passing autofocus, metering, and image information to maintain consistent exposure and dependable AF tracking for fast-moving subjects. Built for field use, the extender has dust- and water-resistant sealing and a quick-release mechanism for rapid mounting and removal, minimizing lens exposure during changeovers.
