Class leading image quality for Nikkor telephoto lenses
Sales start date: 29th January 2010
Nikon UK is launching the new AF-S TELECONVERTER TC-20E III, the world’s first teleconverter with an aspherical lens element. With a completely new optical design, the compact new teleconverter offers class leading image quality for wildlife and sports photography.
Zurab Kiknadze, Product Manager for Lenses, Accessories and Software, Nikon Europe says: “The ground breaking optics in the new AF-S TELECONVERTER TC-20E III allow photographers to extend the reach of their NIKKOR telephoto lens with the confidence that there will be no comprises on image quality.”
World’s first teleconverter with aspherical lens element
The AF-S TELECONVERTER TC-20E III is the world’s first teleconverter with an aspherical lens element, which delivers brilliant image quality in a compact package. Completely compatible with the latest VR, autofocus and metering coupling systems, the AF-S TELECONVERTER TC-20E III is a ‘must have’ addition to any sports or wildlife photographer’s kit.
Built for professional demands
The new AF-S TELECONVERTER TC-20E III 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. This magnification factor comes at the cost of reduced light transmission which reduces the effective minimum aperture of the lens in use. The AF-S TELECONVERTER 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.
