Canon Extender EF 2X

Canon Extender EF 2X is a teleconverter designed for Canon EF-mount lenses that doubles the effective focal length of a compatible lens. It mounts between the camera body and lens, allowing telephoto lenses to achieve greater reach for subjects such as wildlife, sports, and distant scenes. The extender maintains electronic communication between the camera and lens for autofocus and aperture control with supported lenses. Its optical design is intended to preserve image quality while providing extended magnification for telephoto photography.
