Nikon TC-20E III (2X) Teleconverter
The 2x extender (also known as a teleconverter) will double the focal length of your existing, and will cut back the amount of light by 2 f/stops. For example, using this teleconverter with a 300mm lens will effectively increase the focal length to 600mm. A lens set to f/2.8 will now be f/5.6. Teleconverters are best used with longer telephoto lenses and are not recommended for lenses wider than 50mm.
