From Kenko

The Kenko Teleplus MC4 DG 2x Conversion Lens will multiply the focal length of the existing lens by 2x, and will cut back the amount of light by 2 f/stops. For example, using a 2x teleconverter with a 300mm lens will effectively increase the focal length to 600mm. A lens set to f/2.8 will now be f/5.6. Teleconverters are not recommended for lenses wider than 50mm, e.g. 28-105mm. However, full AF operation is only possible with lenses with open aperture of f/2.8 or brighter. Please be aware that AF will work properly only if there is enough light and contrast on the subject to activate the camera’s AF sensors. Manual focusing is recommended when using lenses with smaller open f-stop value than those given above.

At first, I had reservations about buying this item. I own a Nikon D80 and planned on using it with my Nikon 180mm f2.8 D lens. Since Nikon doesn’t make a teleconverter for the 180mm, I went ahead and bought it.

First off, I’m thrilled with the results. This item really delivers. Not only does it work flawlessly with the lens and camera, but it also produces sharp images. I like it so much I sold my 300mm f4 Sigma lens on ebay. This teleconverter gives me the equivalent of a 360mm f5.6, at about half the weight.

I can’t stress enough how happy I am with this teleconverter. Bravo!
