The Canon Extender RF 2x is a 2x teleconverter designed for select Canon RF-mount lenses, extending focal length for wildlife, sports, bird, and distant-subject photography. It provides 2x magnification with a 2-stop light loss while maintaining camera-lens communication.

The extender supports metering, autofocus, image stabilization, and Exif data transmission. Its dust- and water-resistant construction and heat-shield exterior make it suitable for photographers requiring additional telephoto reach in outdoor shooting environments.
