Product Highlights
  • Doubles Focal Length of Nikon F Lens
  • 7 Optical Elements for Sharp Images

Bower's 2x DGII Teleconverter (7 Element) for Nikon will effectively double the focal length of your Nikon lens, while maintaining the autofocus function--a 35 mm lens becomes a 70 mm lens. This 7-element teleconverter uses multi-coated optics to deliver improved image quality. With an 85 mm f/1.4 lens, for example, the focal length will become 170 mm, which effectively sets the maximum aperture at f/2.8 (cutting the amount of light captured by two f/stops). This teleconverter is a portable, high-quality and versatile accessory that's well worth having in your camera bag. It's only compatible with lenses with a maximum aperture greater than f/4.0 in order to fully utilize its autofocus capabilities.

      Works well. Better quality than I was expecting. Made in Japan. I have to use manual focus with this lens.

            Comments about Bower 2x DGII Teleconverter (7 Elements) for Nikon:

            This is a very good, reasonably priced teleconverter that I now take on all trails for nature photos. Mounting seemed a bit tight at first, but now is familiar and quick. I've used it on my D700 with both appropriate (>70mm, max ap of at least 4) and inappropriate (35mm, zoom with max ap of 5.6) lenses, and it's worked very well except for lack of crisp focus on the 35mm, for which it was not designed. I was very pleased with the sharp focus (manual, of course) on a 70-300mm f4.5-5.6 zoom lens at full extension in full sun, even though that is not a recommended lens type. AF on appropriate lenses works well & quickly, and metering etc. carries through fine for me especially in low/med light. One tip though is when shooting in full daylight, be sure to take another shot at lower EV, since otherwise the image you get at what the meter shows as ideal exposure may in fact be too bright. This TC for my amateur use certainly beats carrying the weight or expense of a super telephoto.
