Ideal for press, sports and nature photography, the extender increases the focal length of Canon L-series telephoto or telephoto zoom lens' by a factor of 2x, with higher AF accuracy and improved communication between camera and lens. The Extender EF 2x III is specially designed to work in conjunction with L-series IS super-telephoto lenses, extending their focal length by a factor of 2x. The extender's design ensures there is no loss of lens performance or image quality. 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. A built in microprocessor provides accurate transfer of data from between the lens and camera delivering an improved performance in AF and metering. The Extender EF 2x 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 two stop.
