1 - Camera lens. 2 - Teleconverter. 3 - Camera body. A teleconverter (sometimes called tele extender) is a secondary lens which is mounted between the camera and a photographic lens. Its job is to enlarge the central part of an image obtained by the objective lens.
Thus, a 400mm lens with a 1.4 Ã teleconverter attached provides the same magnification as a 560mm lens, since 1.4 Ã 400 = 560. Similarly, a 400mm lens with a 2 Ã converter produces the same magnification as a true 800mm lens. For birders, teleconverters can be a godsend.
