Canon EF 1.4x III Converter-Canon CH Warranty

More focal length

The Extender EF 1.4x III is designed specifically for Canon's L-series IS super telephoto lenses. It extends their focal length by a factor of 1.4 and is designed to have virtually no impact on the lens' outstanding performance and imaging quality.

First-class construction

Optimized materials in the lens barrel for reflection reduction and coating on the outer edges of the lenses reduce aperture reflections. The extender is excellently protected against dust and splash water - this also contributes to the high image quality.

Optimized communication between lens and camera

The integrated microprocessor ensures precise data transfer of subject parameters between lens and camera. This ensures precise automatic focusing.

Suitable for many Canon L-series telephoto and telephoto zoom lenses

The Extender EF 1.4x III is suitable for most of Canon's professional L-series telephoto and telezoom lenses. It extends the focal length while reducing the effective aperture of the lens by one stop.
