Sigma 2X EX DG APO TELE-CONVERTER AF For Sigma Cameras
The Sigma 2x EX APO Tele Converter (also known as a tele-extender) 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 300 mm lens will effectively increase the focal length to 600 mm. A lens set to f/2.8 will now be f/5.6.
