Zur Zeit liegt leider nur ein englischer Infotext vor:
The 1.4 EX Tele Converter is placed between the lens and the camera, and it allows the photographer to use the 70-200mm f/2.8 lens as a 98-280m f/4 lens, and the 300mm f/2.8 lens as a 420mm f/4 lens; the high optical performance is maintained and the AF speed is not affected. The Tele converter provides a larger focal length and allows greater mobility, which is useful for taking photographs of sport, nature and landscapes.
