Canon RF 1.4x Extender

More reach, no loss of image quality

The Canon RF 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 on the Canon RF 1.4x Extender by reducing the surfaces in contact with the air as much as possible.

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.

Seamless integration with Canon RF 100-500mm F4.5-7.1L IS USM

A mechanism which limits the zooming of the RF 100-500mm F4.5-7.1L IS USM zoom range (300 to 500 mm) prevents the lens elements hitting those of the extender.

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.
