Allowing professional photographers to shoot distant subjects without having to carry a number of heavy lenses with them, this new extender ensures there is no compromise on image quality. The Extender EF 2x III features nine lens elements in five groups, ensuring improved optical performance.

Please Note: The Canon EF 2.0x III Extender is only compatible with specific Canon EF L-series lenses. It may also only have limited functionality with some of those lenses. Please see the compatibility table below to determine which lenses are usable and the level of functionality possible.

To facilitate the accurate transfer of imaging data between the lens and camera body, it features an integrated processor which ensures all focusing, metering and ID information is available – allowing the photographer to capture crisp, well-exposed images. When combined with the latest range of premium Canon L-series lenses, this extender enables higher AF accuracy compared to previous generations, ensuring professionals achieve perfectly sharp shots, even when capturing moving subjects. 

The Extender EF 2x III has been designed to complement the latest range of L-series lenses, matching their appearance and offering a visible differentiation from previous models. A carefully positioned lens release mechanism also makes it easy to mount the extender quickly, reducing the time that the camera and lens are exposed to the environment. The extender offers the exceptional build-quality expected from Canon’s professional products, and is resistant to both dust and water, allowing photographers to use it in extreme shooting conditions.
