Canon RF 1.4x Extender

The Canon RF 1.4x Extender teleconverter is the perfect choice for enthusiast and professional photographers seeking more magnification from their RF lenses. Boosting focal length by 1.4x it is ideal for press, nature and sport photographers. The 1.4x extender features high-refraction, low-dispersion glass to control curvature of field and chromatic aberration of magnification for the highest image quality.

Advanced lens design
As well as optimised lens coatings, a 3-layer combined lens helps to reduce ghosting by reducing the surfaces in contact with the air as much as possible.

No compromise construction
Designed for reliability and durability with vibrational shock resistance plus dust and water resistance for use by professionals and high-end amateurs.

Designed to perform in extremes
The exterior is coated in the same white heat shield coating as used on the RF 100-500mm F4.5-7.1L IS USM and RF 70-200mm lens to prevent deterioration in performance in high temperatures.
