Canon Extender RF 1.4x

Compatible with:

Canon RF 100-500mm F4.5-7.1 L IS USM
Canon RF 600mm F11 IS STM
Canon RF 800mm F11 IS STM

More reach, no loss of image quality

The 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.

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 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.

Customer Reviews

By Roger on 16th October 2021

"The 1.4 converter, being a Canon product, does not disappoint. I found my 600mm lens was getting too heavy for hand holding, so switched to the 100-500 lens + 1.4 T/c. So extra reach and great quality maintained. Castle Camera's staff are always very helpful and so friendly."

By Bob on 15th May 2021

"Service was good and communication spot on. The 1.4x extender does exactly what is expected without any noticeable degradation of image quality. If you need to get closer to your subject I would recommend the product. Only negative is the price... Too expensive in my view."
