The Nikon TC-201 is a 2x teleconverter (also known as a tele-extender) that will multiply the focal length of the existing lens by 2x, and will cut back the amount of light by 2 f/stops. For example, using a 2x teleconverter with a 100mm lens will effectively increase the focal length to 200mm. A lens set to f/2.8 will now be f/5.6.
NOTE: Due to the high-quality design of this converter (5 elements/5 groups), the teleconverter will only fit and work with a select range of lenses. However, even with the listed AF lenses, only manual focus operation is possible. The following lenses are compatible:
AF lenses, in manual mode:
MF Manual Focus lenses:
* Occasional vignetting, when used at aperture smaller than f/11 with high-shutter speeds occasional uneven exposure might occur.
# Usuable, but occasional vignetting possible
