Nikon TC-20E III AF-S 2x Teleconverter

It is designed to provide a seamless fit with the NIKKOR range of compatible telephoto lenses, and features rubber seals for body mount, tough release mechanism for intensive use and an oversized button for fast removal with gloved hands. It comes with newly designed caps and a practical storage pouch to protect it when not in use.

Teleconverters are attached between the camera body and telephoto lens to multiply focal length without affecting closest focusing distance. The TC-20E III reduces aperture by two stops. So when attached to an f/2 aperture lens (such as the AF-S VR 200mm f/2G) the minimum aperture becomes f/4.
