Summary: Read the full compatibility specs on this teleconverter before buying, unlike I did. While this teleconverter is compatible with the Nikon 80-200mm f/2.8, it's only compatible for the AFS version of the lens and not the AF lens. And better yet, Nikon doesn't even make a teleconverter for this lens, which so you'll be SOL if you want one.
Buyer Beware - Does Not Fit All Nikon Digital SLR Cameras

Summary: the "ad" for this converter states for Nikon Digital SLR Cameras...It does not fit all Nikon Digital Cameras and lenses.... After searching, hidden in all the comments, a lens compatibility chart was found and it fits a very narrow range of lenses for Nikon.... Ad should show the facts more clearly............
Summary: All the reviews of the product were good, however it would not adapt to the Nikon D5100. I had to return it. If it had worked I would most likely have kept and used it...The vendor gave good service, had good communications and was prompt on delivery and return of the Converter.
Summary: I really enjoy using this Tele-convertor. It does a great job paired along with my Nikon D7000 and Nikkor 70-200mm 2.8 VR1..... Ive read and watched so many reviews about this product and almost didnt buy one after hearing about soft images... Thats not the case for me. I'll admit I do get a few soft shots here and there but I believe it is because of maybe my era not the lens combo..
Good product, but do your homework before ordering

Summary: Buying any teleconverter takes a good bit of homework. Teleconverters are not nearly as compatible with lenses - including of the same manufacturer - as most people may assume. Though I use this with an older Nikkor 70~200mm lens for sports events, it is actually designed for longer telephotos. If I were to do it over again, I probably would choose a shorter Nikon teleconverter given the pixel-peeping level of softness for this shorter lens.
Summary: The TC-20E-II is the 4th generation of AF-S/I teleconveters from Nikon, All the TC20's are opically excellent however they are speclialized teleconverters designed for Nikon's professional telephoto and telephoto zoom lenses. They are NOT general purpose teleconverters intended to make normal lenses telephoto lenses. The design intent is to allow a photographer to carry a 300 2.8 AF-I or AF-S and this teleconverter to give the photographer a 600 5.6 lens.
