Without a doubt, the new Nikon TC-20E III is a huge improvement over the Nikon TC-20E II. While I have not had a chance to actually test both side-by-side, I have tried using the Nikon TC-20E II in the past and was very disappointed with the results, even when used with fast lenses likeNikon 300mm...

This teleconverter works very well optically, but one does lose some light. Because of this, auto focus is not possible on many lenses. I use it with my Nikkor 200-500 mm lens to increase my reach to 600-1000, and it does work well optically.

Although I lose autofocus with my 200-500, I still find it useful in specific applications. Bought this for the upcomming eagle watching season on the Mississippi. But when I tried it out on my DX body in my backyard, I realized it gives me macro capabilities from 7 feet away, and I could use my...

Be sure that this works for YOUR lens. Realize that some lenses will loose auto focus. Also realize that viewfinder will be much dimer with this. Otherwise, I normally have the 1.2x Teleconverter with me at all times, just incase, with the 2x for really hard cases, e.g.

I purchased this lens a couple years ago & really enjoy it. It's quick and sharp! Using the TC-20E III teleconverter is a game changer :-)

I have found this AF-S Teleconverter TC-20E lll to be very effective when used with lenses that have f stops at 4 or larger. I found that this teleconverter when coupled with the older Nikkor AF-S 80-200mm f2.8 D lens on the Nikon D500 to focus quickly and accurately, even in lower light situations.

Fine clarity and glass, but only after searching did I find that autofocus on most cameras is not supported except at narrow focal lengths. Reduction of light and loss of autofocus does not make this a good wildlife / nature tool; get a better lens instead.

The TC-20E III couples in neatly between my Nikon 810 and 70-200 2.8 lens. All automatic lens functions continue to work fine. I am pleased with the image quality for my purposes. I don't mind the 2-stop loss as I plan to use it outdoors on bright days. The TC-20E III is well made.

I am a Nikon lover but I never got convincing results while using the TC-20E III on my Nikon 70-200 VRII, the images aren't sharp enough for me (at any apertures, mirror up, remote shutter, steady tripod, manual focusing on live view etc.).

I just got this lens today and wanted to give my first impression. I am using this 2x multiplier with a Nikon D750 Nikon 200-500mm lens, very heavy. In bright light the pictures are amazing. In darker settings the pictures are a little softer with more grain.

I dont shoot a lot of long lens situations so this 2x converter is a nice addition to the 70-200mm 2.8. Recently compared the same landscape image shot with the 70-200 2.8 with and without the 2x converter and was very pleased with the overall sharpness, color and contrast.
