Product Overview
High-performance teleconverter that doubles the effective focal length of certain NIKKOR lenses without increasing the closest focusing distance. As the world's first teleconverter to incorporate an aspherical lens element, it offers images with outstanding resolution and contrast. Compact and lightweight, it is a cost-effective and practical solution for those times when it is not possible to carry an extra telephoto lens with you.
