Canon Extender EF 1.4X III: Enhanced Performance and Versatility

The Canon Extender EF 1.4X III is specifically designed for select Canon EF mount L-series telephoto lenses, providing a 1.4x increase in focal length without compromising image quality. With its redesigned optics, improved data communication, and enhanced environmental protection, this extender delivers exceptional performance in various shooting conditions. It is particularly beneficial for photojournalists, wildlife, nature, and sports photographers who need to capture distant and challenging subjects, reducing the need for heavy telephoto lenses.

Superb Image Quality and Coating

The Extender EF 1.4X III features seven optical elements in three groups, all equipped with Canon’s Super Spectra coating to minimize ghosting and flare. The front and rear elements are coated with a Fluorine Coating, making them easier to clean and resistant to water spots and fingerprints.

Efficient Data Transfer and Compatibility

To ensure accurate transfer of imaging data between the lens and camera body, the extender incorporates an integrated processor. This allows for reliable focusing, metering, and ID information, enabling the capture of well-exposed and balanced images. When combined with the latest Canon L-series lenses, the extender ensures precise autofocus even when photographing moving subjects. It’s worth noting that the effective maximum aperture is reduced by 1 stop when using the 1.4x extender.

Convenient and Durable Design

The Extender EF 1.4X III features a carefully positioned lens release mechanism, enabling quick and easy mounting while minimizing exposure of the camera and lens to the environment. The extender boasts the exceptional build quality expected from Canon’s professional products and is resistant to dust and water, making it suitable for use in extreme shooting conditions.
