Tamron-F AF Teleconverter 2X N-AFd MC7 for Nikon F brand_Rokinon but it's otherwise pretty goodThe Tamron F AF Teleconverter 2X N AFd MC7 for Nikon F is a 2x teleconverter that can double the focal length of a compatible lens, at the cost of two stops of light. Compatibility is pretty good: itll work with most lenses that dont have a protruding rear element. It even transmits pin drive AF function, which no Nikon branded teleconverter does. In very good condition, with minor cosmetic barrel wear, light internal dust.
