Yes, Nikon teleconverters work with Tamron lenses. Teleconverters are designed to increase the focal length of a lens, and they are attached between the camera body and lens. While Tamron does not make its own teleconverters, third-party manufacturers produce them for use with Nikon F-mount cameras and lenses. When choosing a teleconverter, it is important to consider the maximum aperture of the lens it will be used with. For example, using a 2x teleconverter with a lens that has a maximum aperture of f/4 will result in an effective aperture of f/8.
