What are teleconvertors?
Teleconvertors 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 Nikon Teleconverter TC-20E III reduces aperture by two stops. So when attached to an f/2 aperture lens (such as the Nikon AF-S VR 200mm f/2G) the minimum aperture becomes f/4. The Nikon Teleconverter will begin shipping in January 2010 for an estimated price of $489,00 USD. |
