Nikon TC20E III
December 2009 More Nikon Reviews
The Nikon TC-20E III is Nikon's first new teleconverter since the 1990s.
The older TC-20E and TC-20E II are the same thing as each other.
This new TC-20E III offers a new optical design, adding an aspherical element, which may offer better performance with some lenses. It is also shorter than the TC-20E and TC-20E II.
This is a $500 teleconverter only for Nikon's professional f/2.8 super teles.
It will not autofocus with conventional Nikon AF lenses, and it will not work with most zooms. Don't even think about trying to use it with the 70-300mm VR.
This is a converter for pros who already own super tele lenses. It is not for use on consumer lenses.
See Teleconverters for more.
Nikon says it works only with the:
AF-S 80-200mm f/2.8D IF-ED Nikon's best 80-200mm
AF-S VR 200mm f/2G IF-ED "Super Chubb"
AF-S 300mm f/2.8D IF-ED II
AF-S 300mm f/2.8D IF-ED
AF-S 400mm f/2.8G ED VR
AF-S 400mm f/2.8D IF-ED
AF-I 400mm f/2.8D IF-ED "KIng of Lenses"
It works with these, but without autofocus:
AF-S 500mm f/4G ED VR
AF-S 500mm f/4D IF-ED II
AF-S 500mm f/4D IF-ED
AF-I 500mm f/4D IF-ED
AF-S 600mm f/4D IF-ED II
AF-S 600mm f/4D IF-ED
Nikon calls this the Nikon AF-S Teleconverter TC-20E III
AF-S means Auto Focus - Silent, meaning that this converter only autofocuses with AF-S and AF-I lenses.
7 elements in 5 groups.
One is aspherical.
Teleconverter Cap BF-3A
Rear Lens Cap LF-1
Flexible Lens Pouch CL-0715
2.6" (66mm) diameter x 1.9" (48mm) extension from flange.

Teleconverters don't work alone.
They work only with another lens.
Every lens will work differently. You'll have to see for yourself if the marked decrease in autofocus speed and possibly accuracy, and potential loss of sharpness, is bearable for you.
2x teleconverters have always been too much. They've robbed too much sharpness, and make autofocus poor.
We'll see if this new teleconverter is any better.
I'm not a fan of 2x teleconverters.
1.4x, and maybe1.7x converters give much better results, but since they offer negligible extra magnification, why bother?

I support my growing family through this website, as crazy as it might seem.
If you find this as helpful as a book you might have had to buy or a workshop you may have had to take, feel free to help me continue helping everyone.
The biggest help is to use these links to Adorama, Amazon, Calumet, Ritz, J&R and when you get your goodies. It costs you nothing and is a huge help to me. eBay is always a gamble, but all the other places have the best prices and service, which is why I've used them since before this website existed. I recommend them all personally.
Thanks for reading!
