Nikon TC-20E AF-S Teleconverter III


The Nikon TC-20E AF-S Teleconverter III is a high-performance teleconverter that doubles the effective focal length of certain Nikkor lenses without increasing the closest focusing distance. For example, using this teleconverter with a 200mm lens will effectively increase the focal length to 400mm but will cut out the amount of light by 2 f-stops. It is the world’s first teleconverter to incorporate an aspherical lens element and as a result produces images with outstanding resolution and contrast. The Nikon TC-20E AF-S Teleconverter III is both compact and lightweight, making it a cost-effective and practical solution for those times when it is not possible or desirable to carry an extra telephoto lens with you.
