Nikon Nikkor TC-20E / TC-20EII 2x Teleconverter AFS / D mount Black New in Box

Description

Nikon TC-20E / TC-20EII
2x Tele-converter Nikon AFS mount Black – New - Boxed
The Nikon TC-20E is a 2x tele-converter. It works only with the Nikon's
AF-I
and
AF-S
lenses. One cannot mount any other lenses on it unless one grinds down lugs on the female tele-converter mount at a machine shop.
Nikon's first AF 2x tele-converter was called the TC-20E. It was marked "
AF-I
" for the only kind of lenses with which it worked when it was introduced. As Nikon introduced
AF-S
lenses, these converters worked perfectly, but innocent people were confused as to why it said AF-I instead of AF-S.
Nikon tweaked the cosmetics, changed the lettering to read "AF-S" and renamed it the TC-20E-II. Nikon made about 20,000 of the original TC-20E, and as of 2008, has made about 15,000 of the newer TC-20E II. Both converters are identical except for the name and trim. Both work with both
AF-I
and
AF-S
lenses. It will also work with the newer digital cameras, you'll need to check with which ones on the Nikon site - in general, you'll get the best performance when paired with a "fast" lens, as you'll lose 2 stops when using a 2x tele-converter.
