The Canon EF Extender 1.4x III is a popular teleconverter. Key features include:

  • Improved Optical Performance

  • Integrated Processor

  • Fluorine Coating

High Quality Optics. The Canon 1.4x Teleconverter III features three groups of seven elements that ensure improved optical performance. All optical elements use Canon’s super-spectra coating, which reduces ghosting and flare to minimize post-processing requirements and a fluorine coating on the front and rear elements makes smudge marks much easier to clean.

Full Electronic Pass-Through. The extender features an integrated processor which ensures all focusing, metering, and ID information is available. Canon claims that, when combined with the range of premium Canon L-series lenses, these extenders enable higher AF accuracy.

Q & A

Does this teleconverter support autofocus?

  • This teleconverter only supports autofocus if the effective maximum aperture of the lens and teleconverter combo does not exceed the limits of your chosen Canon camera. This teleconverter adds one stop, so f/2.8 becomes f/4, f/4 becomes f/5.6, f/5.6 becomes f/8, etc. Check your manual or feel free to contact us to verify if autofocus will work.

Which lenses do you recommend for use with this teleconverter?

  • If you rent this teleconverter and attempt to use it with any lens other than the ones listed under “Recommended Lenses,” there’s a chance it won’t work. If it does work, you very likely won’t be happy with the results.

Is this teleconverter incompatible with any lenses?

  • The Canon 1.4x will not fit on wide-angle zooms, standard zooms, wide-angle primes, or many third-party lenses.
