Canon EF Extender 1.4x III

Available Today

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.

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.

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

The Canon 1.4X TC III is a great option if you need more reach with your compatible telephoto lens. While previous generations had a very noticeable affect on image quality and AF performance, the TC III is huge leap forward. When used with a 70-200mm f/2.8L IS II, image quality and AF remains very high. Throw it on a Canon supertele, and you’d be hard-pressed to notice a difference. However, as a general rule, remember that low light does not mix well with teleconverters. You will see focus hunting.
