Sigma 1.4X APO EX DG Teleconvertor Lens for Nikon
The Sigma 1.4x DG EX APO Tele Converter will multiply the focal length of your existing Nikon lens by 1.4x, and will cut back the amount of light by one f/stop. For example, using a 1.4x teleconverter with a 300mm lens will effectively increase the focal length to 420mm. A lens set to f/2.8 will now be f/4.
