Nikon AF Teleconverter TC-16A &nbsptype_Darkroom Accessories and AC adapterThe unique TC 16A teleconverter gives autofocus capabilities to many F mount manual focus lenses! When used on a suitable camera body, this teleconverter dials in focus automatically after manually focusing to the general distance. Compatibility is limited, however: Nikon recommends the TC 16A only with the F 501 N2020, but several other bodies including the F4 and F N90 work as well. Please confirm compatibility with your intended camera body. Good
