Canon EF 1.4x III Extender | 1.4x Teleconverter for EF Lenses

The Canon EF 1.4x III Extender is a professional teleconverter designed to increase the effective focal length of compatible Canon EF lenses by 1.4x, giving photographers additional telephoto reach without the need to carry a longer lens. It is an excellent accessory for wildlife, bird, sports and nature photography where getting closer to distant subjects is essential.

Designed for use with compatible Canon EF telephoto lenses, the EF 1.4x III incorporates Canon's advanced optical design to help maintain excellent image quality while extending the lens's reach. Its compact form makes it easy to carry in a camera bag and allows photographers to add extra focal length when required.

For example, pairing a compatible 300mm lens with the EF 1.4x III produces an effective focal length of approximately 420mm, providing a tighter field of view and greater subject magnification. The extender is particularly useful when working with distant wildlife or sports subjects where changing to a larger telephoto lens may not be practical.
