The solution to this lens is to use manual focus. As per another reviewer, for most autofocus systems to work the aperature must be 6 or greater (that means a number smaller than six). But, a 2x converter adds two f-stops to the aperature (decreases the aperature) so you must have a lens that goes no lower than f/4 for the aperature. Most zoom lenses go to somewhere are 5.3 to even higher numbers and that means that as you zoom in on a subject the autofocus will quit working. The answer is that with a teleconverter expect to use manual focus when using a zoom lens. The lens will work fine.Most of the consumer Reviews tell that the "Vivitar 2X7N Auto Focus Teleconverter Lens for Nikon (2X7N)" are high quality item.
