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.
