Cheap option for doubling zoom rangeJuly 10, 2008 1 out of 1 found this review helpful
This 2X teleconverter is a great option for anyone with a short telephoto lens wanting to double the zoom range without buying a dedicated telephoto lens. If your lens is slower than f/4 it will not autofocus in the telephoto range, but you can focus manually. Shoot at high ISO with a slower lens for best results, as it does restrict light. One added bonus is that the teleconverter acts as an extension tube, thus enhancing macro ability. All in all, it is a fun inexpensive device that seems well made and durable.
