This is a Canon Extender EF 2x III, a professional 2x teleconverter designed for compatible Canon EF telephoto lenses.
It doubles the focal length of compatible Canon EF lenses, making it a useful accessory for wildlife, birding, sports, aviation, and outdoor photography.
For example, a compatible 300mm lens becomes 600mm, and a compatible 400mm lens becomes 800mm.
The Extender EF 2x III was designed for Canon’s high-end EF super-telephoto lenses and is well known as an essential partner for Canon’s famous white L-series lenses.
