Nikon Auto Focus-S FX TC-20E III Teleconverter Lens with Auto Focus for Nikon DSLR Cameras

I really wanted this to work, and based on some of the positive reviews I was hopeful. However I found it was worse than nothing on the long lens I wanted to use it with. Im giving it two stars vs. one because it allowed the camera and lens to work properly. The professional lens is on Nikons approved list for this teleconverter. I shot several hundred images in the field with a Nikon 400mm F2.8 VR lens and this 2x tele on a tripod with a Wimberley Gimbal head, shooting with a D600 at shutter speed of 1600, F8. Focus distance was 200 feet and beyond. By itself this is a very sharp lens, but none of these images were sharp, all were soft focus. Too soft for me. Lack of animal eye highlights was really an issue. After this I did a simple test comparing an enlarged 400mm image with an 800mm image made with the tele, and found the native 400mm image was far sharper and had better contrast. Example images attached. I finished my field shoot using just the lens, and got results I could live with. In all cases I was better off without the tele than with it, so Ive returned it. I dont think the description is quite right... I didnt get any cleaning set in the Nikon box.

after reading all the comments I was a bit skeptical if it would work well. It worked really well for the purpose I bought which was to photograph the one of the super moons, to be used with the Nikon 200-500mm mounted on a D750. Unfortunately, people dont check the compatibility chart and say the teleconverter is not good because it is not compatible with their lenses. Also it does not autofocus but I was aware of it. I really like the results. Just be realistic and do your research.

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. One thing about this lens is my Nikon D750 & Nikon 200-500mm lens can still auto focus, which is different from what I read online. So far a great lens, if this changes I’ll let you know.

Economical way to extend focal length Nikon TC-20E III 2x Teleconverter works great with my Nikon 70-200mm f4, continuous focus mode worked flawlessly and images lost little or no sharpness. Picture says a thousand words shot at 400mm, f8, 200 ISO, and 1/1600

Works fantastically with my Nikon 300mm f/2.8 lens, and it replaces my TC-20E II teleconverter that suddenly stopped working while I was on a hike. Nikon told me it was too old to repair through them, though I might be able to through a 3rd-party repair service, but I need my equipment to work when Im out, or covering an event, so I just bought a new one (And a warranty!). I use this with a D500, and the captures Im getting are to my eye even sharper than when I used my old TC-20E II. Im annoyed that the ONE piece of equipment that I didnt have a redundant backup for failed me in the field, but Ive learned my lesson, and now have a standby 2X teleconverter just like my back up camera bodies, flashes, and lenses. Live and learn!

First off, you will lose some sharpness and contrast with this teleconverter. Second off, you will lose some sharpness and contrast with every teleconverter so you should be aware of this before buying one. Third off, you will not lose as much sharpness and contrast with this teleconverter as you will with previous iterations or with generic third party converters. If you need a 2x teleconverter for compatible Nikon lenses, this is the way to go. I mostly use this with a 70-200mm f/4 as I dont particularly need a faster 400mm nor do I feel like paying for one (lets not even mention how heavy a 400mm prime can be). In this particular case, its superb and requires just a touch of sharpening and contrast adjustment in Photoshop or Lightroom. Focusing isnt super fast on a D600, but its adequate. If I was going for better performance here then I would have bought a more substantial 400mm. Ive also used it with a 300mm f/2.8 and I can get away without additional sharpening in post, but just because I can get away with it doesnt mean that I will. Focus speed is also pretty excellent with the 300mm (effectively a 600mm f/5.6). Overall, Im pleased. It does precisely what I want it to, nothing more and nothing less.

I have paired this with the 70-200mm VR II on a D700 and am so far very impressed with the performance. There is some loss of sharpness, but it retains detail far more than I was expecting, and it is much, much, much better than the TC-20E II. Given that the III is also smaller and lighter makes it well worth the extra money in my book. AF with this combination is still fast and sure, about on par with the 70-300mm VR if not a bit snappier and with less hunting, and is fast enough for sports in daylight. I was also surprised by how well the bokeh holds up; there are some weird effects due the TC, but the bokeh (at least on the 70-200mm VR II) still maintains a creamy quality and the artifacts are not as distracting as they are with the previous generation TCs. It is the only 2x teleconverter I would consider using on the 70-200 (the TC-20E II made everything too mushy). On an FX body, this combination is a very viable alternative to 200-400mm VR if the latter is just too expensive for your budget, too heavy to be practical, or both, particularly if conditions allow you to shoot at f/8 through f/16.

Ive had a Kenko 1.4 teleconverter for years that works with every Nikon body and lens that I own including the 28-300 that I got with my D810. I figured it was time to increase the power and thought it was worth spending the extra money for Nikon equipment. Nikon has always boasted compatibility, thats why you stick with a brand. When I bought this there was a dropdown to select your camera which I thought was odd as it is a Nikon, I just figured maybe it was auto focus or something which doesnt bother me. But when I got this teleconverter something was wrong, the lens wasnt going to fit. So I spent some time searching online and found Nikon doesnt care so much about compatibility and even had an excuse that you wouldnt want to increase the power of your zoom. What? It was obviously an excuse, who wouldnt want to convert their 300 to 600 or even 900 in DX mode even its not perfect. What a huge disappointment. Really decreases my desire to upgrade to the new mirrorless cameras...

First let me say that Im a novice at photography. About the only thing I dont photograph is people. Lately I have enjoyed photographing birds and that is why I purchased the Nikon TC-20E III 2x Teleconverter. Previously I had been using my Nikon D7000 and Nikon 300mm f/4.0 lens coupled with the Nikon TC-14E II teleconverter which was giving me good results but wanted a little more reach if possible. This converter so far has passed my expectations. I am aware that Nikon claims that the TC-20E III 2x teleconverter will not auto focus with the 300mm f/4.0 lens or the Nikon 105mm f/2.8G ED-IF AF-S VR Micro-Nikkor Lens for that matter, but in the couple of days Ive had it, it has been autofocusing really well. Right after the sun set this evening I attempted to photograph a red finch about 50 yards away and had to manual focus, but had been shooting that distance all day with auto focus and while viewing only with maximum zoom on my LCD screen the results have been looking well. This week I will catalog and review my photos in Lightroom. Also I plan on taking the trip into the forest or one of the lakes to see if I can capture a bald eagle. If I experience problems in the future I will update this review. But at the present the TC-20E III 2x Teleconverter will remain attached to my 300mm f/4.0 lens as did the TC-14E II previously. On another note it works quit well with my Nikon 105mm f/2.8G ED-IF AF-S VR Micro-Nikkor Lens, but since I have the Nikon TC-14E II teleconverter it will probably remain a part of my micro lens.

I bought this teleconverter because I recently acquired a Nikkor 70-200mm f/2.8 VR ii lens and had a Nikkor 80-400mm f/4.5-5.6D VR lens that I didnt want to lug around as well. I still wanted the range of 80-400mm, but both of these lenses are large and heavy. I read review after review on this teleconverter. You have those who praise it and those that hate it. Well, somebody put one used up for sale here at a price I couldnt pass on. A few days later I had the tele in hand. Nikkor 80-400mm f/4.5-5.6D VR vs Nikkor 70-200mm f/2.8 VR ii + Nikon TC-20E III In my opinion, with the samples that I have, the tele comb delivered more sharp images per shoot than the 80-400mm. Especially at 400mm. I would try as I might with the 80-400mm and it always felt soft most of the time. I shot both on my D600 and only if you pixel peep on the tele combo can you see any lack of sharpness on occasion. Im happy with my purchase and glad I did not listen to the naysayers. If you can afford to be that picky go buy a 400 prime. *I have uploaded an image and a 100% crop for you to judge for yourself if its sharp enough.
