MINT in Box Canon EXTENDER EF 2x II AF Teleconverter Lens EOS EF Mount JAPAN

The Canon Extender EF 2x II is a genuine Canon teleconverter designed for the EF mount system, doubling the effective focal length of compatible EF lenses. As a second-generation Extender, it incorporates optical improvements over the original EF 2x for improved resolution and contrast. The 2x magnification doubles the effective focal length of the attached lens — a 300mm f/2.8 becomes a 600mm f/5.6, for example. This provides significant additional reach for wildlife, sports, and aviation photography without the bulk and cost of a dedicated super-telephoto lens. The second-generation optical formula incorporates improvements to edge-to-edge sharpness and aberration control compared to the original EF 2x. Canon's internal optical coatings maintain contrast and minimize flare when used w.
