Features

Focal length extension for super-telephoto lenses

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.

High-quality construction

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 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.

Dust- and Drip-Resistant, Fluorine Coating

Dust- and drip-proof for shooting under harsh conditions

Many of Canon’s L lenses come with a dust- and drip-proof structure, with rubber sealing applied to the interface area between the joint of the mount and the camera, as well as sealing at the movable parts such as the focusing ring and the lens extension tube. Rubber materials are also employed even at the smallest parts, such as the switch panel and the insertion slot of the drop-in filter compartments. The excellent dust- and drip-resistance enhances the usability of lenses under adverse weather, and helps to address the needs of professional photographers who are required to perform shoots under harsh shooting conditions. Fluorine-coated lenses allow dirt attached to the lens to be wiped off easily.
