Nikon TC-20E III AF-S Tele Converter – Excellent low cost choice for supertelephoto.

I have used this now on a few different lenses, and after some fine tuning, the image quality has been excellent.

I have 4 compatible lenses which all autofocus with this converter even on older bodies. The lenses i use it with are 105 f2. 8 macro which does autofocus even though nikon compatibility chart say it does not (not tested for macro work). It also works well with my 70-200 f4, 300 f2. 8 vrii and even under indoor lighting with my recently procured 300 f4 pf. 7 tcii converters and certainly with the f4 lenses autofocus does noticeably slow down with each subsequent size of converter. What surprised me was that even my old bodies d50, d300 and d700 still work with my f4 lenses plus this 2x converter even though their af is only rated to f5.

This converters works more ‘acceptably’ with wider aperture and slightly lower length lenses. I bought this to go with my af-s 80-400mm f4. 6 vr nikkor, which the chart says is compatible, and it is but only to a point. As the max aperture becomes f11, one stop down for max sharpness and you get f16. The converter is calibrated to work to f8. I only get an almost functioning af at 250mm (500mm) @ f11, anything more the af just hunts continually. Sharpness is acceptable/good. I bought it second hand, thankfully. It’s a good 2x converter but with very limited af very disappointing.

Perfect just what was needed, great service.

I just love this tele converter. The only drawback is that i may have to resort to manually focus, using some lenses. In fact, with an f/4 lens, it becomes very difficult using automatic focus( with the tele converter mounted), unless you are using a professional camera. The quality of the pictures is superb. This is far better than previous release ii and all defects have been solved.

I have found the nikon tc-20e iii af-s teleconverter very usefull. I take it with me every time i go out to take bird photo’s.

Sorry i didnt purchase this from amazon but i thought my experience might be useful to other potential buyers. I had the misfortune to suffer a stroke a few years ago, which means i am not able to zoom any more. I passed my pro zooms to my son who makes excellent use of them. I have now set about buying prime lenses again and this converter in conjunction with the 105mm macro f2. 8 is absolute magic for a guy with one arm. It focuses correctly despite nikon saying it shouldnt. It is slightly less sharp than the 1. 4x which is slightly less sharp than the lens alone but i’m talking ao blow ups regullarly which my 800e manages quite comfortably at 2000iso. I am now waiting for the new 300mm f4 which from all the results i’ve seen will mean i will be able to hand hold one handed with the equivalent of a 600mm albeit at f8 but with 2000iso who cares we do have some sunny days in the uk. When you buy this converter assuming compatability you are effectively doubling the number of lenses you own if they are good primes so £400 seens like a bargin to me and as a bonus the close focus distance doesnt change.

At this price you would expect a quality product – and that whats nikon gives. Excellent value in doubling the focal length of you original lens.

Great piece of kit which allows me to turn my 70-200mm zoom lens into a 140-400mm zoom lens. This means i can now do wildlife photography much easier than before owning the teleconverter.

Does what it says on the packet.
