Canon Extender EF2X III 【New, Unused】 I am selling this because I have another telephoto lens. This is a high-performance extender that doubles the focal length of your lens for photography. Weighing only 325g, it's lightweight and easy to carry, yet it allows for super-telephoto shooting. It's great for moving around at events like children's sports days and recitals, and it's very convenient and excellent to handle. I think it will be more useful than a super-telephoto lens that requires a tripod or monopod. It also responds well to Eye AF (limited to cameras with Eye AF). The resolution is also improved compared to the EXTENDER EF2×Ⅱ. It's functional and cost-effective compared to expensive super-telephoto lenses. Please purchase only if you understand that it has been in someone's possession once. The box has some scratches. Immediate purchase is welcome.
