Nikon has issued a development announcement for the NIKKOR Z 120-300mm f/2.8 TC VR S, a telephoto zoom for full-frame Z-mount cameras that carries a built-in 1.4x teleconverter — extending its effective range to 168–420mm at f/4 via a thumb switch on the barrel. The lens joins Nikon’s S-Line, the designation reserved for optics held to the highest internal standard of optical performance and build quality. S-Line membership is not purely marketing; lenses in this tier have consistently delivered the kind of resolution and contrast performance that holds up in demanding professional conditions.
