Tamron is bringing its smallest and lightest F2.8 tele-zoom lens to the Nikon Z Mount. The addition of the wildly popular 70-180mm F/2.8 Di III VC VXD G2, previously only available in E-mount, was announced early Tuesday morning, completing the "Tamron Trinity" of Nikon Z lenses along with the 16-30mm F/2.8 Di III VXD G2 and 28-75mm F/2.8 Di III VXD G2.
