Canon RF 2x Extender

Double Your Reach for Sports, Wildlife, and Press Work

The Canon RF 2x Extender is a teleconverter built for photographers who need substantial extra telephoto reach from select Canon RF super-telephoto lenses. Extend your reach even further with a 2x extender designed specifically for the RF lens system, doubling focal length while maintaining image quality and high-speed communication between camera and lens, making it an ideal choice for press, nature, and sports photographers.

Designed for Serious Distance Without a New Lens

This extender is made for shooters who want maximum reach without the expense of a longer dedicated lens. For example, a 600mm lens paired with the 2x extender becomes a 1200mm lens, giving wildlife and sports photographers dramatically expanded reach for subjects too distant to approach. Buying an extender over a longer lens can make strong financial sense, since very long focal length lenses are considerably more expensive than extenders alone.

Full Communication, Full Functionality

The extender retains communication between the lens and camera body in all aspects, enabling seamless metering, autofocus, and image stabilization along with transmission of Exif data. It features high-refraction, low-dispersion glass to control curvature of field and chromatic aberration, along with optimized coatings and a 3-layer combined lens element designed to reduce ghosting. Note that using the extender reduces light-gathering ability by approximately 2 stops.

Rugged, Field-Ready Construction

The extender is designed for reliability and durability with vibrational shock resistance, plus dust and water resistance for professional and high-end amateur use. Its exterior uses the same white heat shield coating found on select Canon L-series super-telephoto lenses to prevent performance deterioration in high temperatures, and it attaches directly between compatible lenses and the camera body using a smart-connect design.

Important Compatibility Note

This extender only works with a specific set of Canon RF lenses, and attaching it to an incompatible lens can damage both the extender and the lens. Compatible lenses currently include the RF 100-400mm F5.6-8 IS USM, RF 100-500mm F4.5-7.1 L IS USM, RF 400mm F2.8 L IS USM, RF 600mm F4 L IS USM, RF 600mm F11 IS STM, RF 800mm F5.6 L IS USM, RF 800mm F11 IS STM, RF 1200mm F8 L IS USM, and the RF 70-200mm F2.8 L IS USM Z. The standard RF 70-200mm F2.8 L IS USM and most standard zooms are not compatible. When used with the RF 100-500mm, the lens's zoom range is limited to 300-500mm while the extender is attached.

A Strong Choice for Doubling Telephoto Reach

The Canon RF 2x Extender is a smart choice for wildlife, sports, and press photographers who already own a compatible RF super-telephoto lens and want to dramatically extend their reach without buying a new lens. It offers substantial magnification while preserving autofocus and stabilization performance, making it a valuable addition to a serious telephoto kit.
