Good used Nikon TC-14E AF-I Teleconverter 1.4x for AF-S and AF-I Lenses. Tested with a 600mm f/4 D II AF-S lens, works perfectly.
Some exterior wear from use, no functional issues. All movements are smooth and easy.
Excellent optics, just a tiny scuff on the front glass coating that does no show in any images in any way.
Comes with front and rear caps, as shown.
Fast, secure shipping.
Thank you for looking!
