Canon Extender EF 1.4X III (4409B002) bundle with backpack, 64GB card, accessories

Canon Extender EF 1.4X III bundle

This bundle centres on the Canon Extender EF 1.4X III, a telephoto converter made for select Canon EF mount L-series lenses. It multiplies focal length by 1.4x while preserving image quality through redesigned optics and Super Spectra coating. The package adds a Pro Sling backpack, a SanDisk 64GB Ultra SDXC card, flexible tripod, cleaning kit and other accessories for photographers who need extended reach in the field.

1.4x focal-length multiplier for EF L-series lenses

The extender works only with compatible Canon EF mount L-series telephoto lenses and increases their focal length by a factor of 1.4x. It uses seven optical elements in three groups with Fluorine coating on front and rear surfaces to resist smudges. Improved data communication between lens and camera maintains autofocus and exposure accuracy, while enhanced environmental protection helps in adverse conditions.

Simple attachment with front and rear caps included

Mount the extender between a compatible EF L-series lens and the camera body using the standard EF bayonet; no tools are required. The bundle supplies a Canon Extender Cap E II front cap and a Canon Lens Dust Cap E rear cap plus the LP811 case, so the glass stays protected when not in use. Ensure the lens is on the supported list, otherwise autofocus and metering may not function correctly.
