The 2x extender (also known as a teleconverter) will double the focal length of your existing lens, and will cut back the amount of light by 2 fstops. For example, using this teleconverter with a 300mm lens will effectively increase the focal length to 600mm. A lens set to f2.8 will now be f5.6. Teleconverters are best used with longer telephoto lenses and are not recommended for lenses wider than 50mm, e.g. 28-105mm (35mm format).
