Canon Extender EF 1,4x - Ideal for press, sports and nature photography, this compact extender increases the focal length of Canon L-series telephoto or telephoto zoom lens by a factor of 1.4x, with higher AF accuracy and improved communication between camera and lens.
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.
Improved communication between lens and camera
A built in microprocessor provides accurate transfer of data from between the lens and camera delivering an improved performance in AF and metering.
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.
