TC-201
2x Teleconverter
The Nikon TC-201 is a 2x manual focus teleconverter that doubles the focal length of your lens and renders any lens it works with behave as a manual focus lens. It features an aperture coupling range from f/2 to f/32 and an effective aperture from f/4 to f/64. This seven-elements-in-five-groups lens is coated with the Nikon Integrated Coating on the air-to-glass surfaces on the lens elements to provide great contrast and accurate colour rendition. Thie TC-201 differs from its close sibling--the TC-200--in that it features an extra coupling to enable the maximum possible aperture lug-read by the FA, EM, and F4, as well as provide additional exposure options such as matrix metering on the F4 and FA settings; in addition, you gain an automatic flash control on the EM.
This 230g lens measures 64.5mm in diameter and 52mm in length.
