Nikon TC-1 2x teleconverter for Nikon F
Nikon TC-1 2x teleconverter for Nikon F-mount lenses. This is a manual focus teleconverter, but it can be used with many autofocus lenses which have an aperture control ring (note that the focusing function will still be manual). Aperture coupling is pre-AI pin style. In excellent working order, with some cosmetic wear on the barrel and mount.
