Focal length extension for super-telephoto lenses
The Extender EF 1.4x III is specially designed to work in conjunction with L-series IS super-telephoto lenses, extending their focal length by a factor of 1.4x.
Improved anti-reflection materials inside the lens-barrel and a coating around the outer edges of the lens elements reduce flare. Construction is resistant to dust and water, helping to maintain images quality.
Compatible with L-Series telephoto and telephoto zoom lenses
The Extender EF 1.4x III is compatible with most telephoto and telephoto zoom lenses within Canon’s flagship professional L-series range, extending the focal length while only reducing the effective aperture of the lens by one stop.
Teleconverters reduce the maximum aperture and may affect autofocus. For more information, there is a helpful article, HERE.
