Featuring an updated optical design and refined focusing system, the Tamron 28-75mm f/2.8 Di III VXD G2 is a Nikon Z-mount zoom offering a versatile wide-to-portrait-length range and bright f/2.8 maximum aperture. Revamped optics yield higher resolution and improved sharpness over the previous generation, and the focusing system has been replaced with a VXD (Voice-coil eXtreme-torque Drive) mechanism that achieves faster, more precise performance to suit both stills and video applications. As the second generation of this popular lens, this updated version also sees refinements to the exterior design of the lens, a closer minimum focusing distance of 7.1″, and a new connector port for streamlining the process of working with Tamron Lens Utility software to adjust lens settings.
