Specification
This tele-converter fits between a lens and your Nikon camera, increasing the focal length of the lens by 40% and reducing the maximum aperture by one stop. This is Nikon's third generation converter, which adds support for lenses with an electromagnetic diaphragm, as well as sporting a new optical design that promises to reduce chromatic aberrations created by the converter itself. In this review we will test the converter with a Nikon AF-S 70-200mm f/ VR lens to see how it performs. 
Nikon AF-S Teleconverter TC-14E III Handling and Features
Weighing only 190 grams, this converter is an ideal way of adding extra focal length, without adding much extra weight to carry around. The Build quality of the converter is excellent, with a robust weather sealed construction being employed.
There are few controls on the converter, with only a release latch for locking a lens to the front bayonet sticking out of the side. A rubber gasket on the rear of the converter provides a seal against the camera body to help prevent the ingress of dust and moisture. The seal on any weather resistant Nikon lens then presses against the flat front of the converter. Nikon have applied a fluorine coating to lens surfaces, which is designed to repel dust and moisture too.
This teleconverter has the full compliment of electronic contacts to support AF-S lenses, and newer Nikon lenses that have an electromagnetic aperture diaphragm, such as the new AF-S 400mm f/ lens. There is also a mechanical linkage for operating the aperture on legacy lenses. Screw-driven autofocus lenses and third party lenses can not be mounted on the teleconverter, as there is an extra metal tab on the front bayonet mount to prevent any lens that isn't an AF-S lens being attached. The converter is easy to fit, and the minimum focusing distance of the mounted lens remains unaffected, allowing more of the frame to be filled with less of your subject.
When used with the 70-200mm f/ lens, focus speeds seem largely unaffected, even in relatively low light conditions. 
Nikon AF-S Teleconverter TC-14E III Performance
To test the converter, we checked the clarity produced with the 70-200mm lens at 200mm, with the converter as well as without to see how much effect it has on image quality. Overall, sharpness is reduced compared to using the lens on its own, but only by a very slight, almost imperceptible margin. The lens and converter combination is capable of delivering outstanding sharpness levels when stopped down to by one stop, which is similar to how the lens performs on its own.

Nikon AF-S Teleconverter TC-14E III Verdict
Some people are nervous about using a teleconverter, as they have a reputation of reducing image quality by a noticeable amount. This new converter from Nikon proves that doesn't have to be the case. Unfortunately, the price means that unless you intend to use it with one of Nikon's latest lenses that have an electromagnetic aperture diaphragm for shooting at high frames rates, the cost may be difficult to justify, especially as the MkII version is still available for just over half the price of this optic. Even so, the fluorine coating applied to lens surfaces to repel dust and moisture may be worth it on it's own, if you tend to work out in all weathers, or in dusty and dirty environments. After all, the performance delivered by this accessory is excellent.

How to read our charts
Chromatic aberration is the lens' inability to focus on the sensor or film all colours of visible light at the same point. Severe chromatic aberration gives a noticeable fringing or a halo effect around sharp edges within the picture. It can be cured in software. Apochromatic lenses have special lens elements (aspheric, extra-low dispersion etc) to minimize the problem, hence they usually cost more. For this review, the lens was tested on a Nikon D600 using Imatest.
Falloff of illumination towards the corners of the frame is noticeably reduced with the converter in place. Without the converter, the corners of the frame are stops darker than the image centre at 200mm and maximum aperture. With the converter this is reduced to stops.
