Tamron 28-75mm f/2.8 Di III VXD G2 Lens for the Nikon Z camera is a Nikon Z-mount zoom offering a versatile wide-to-portrait-length range and bright f/2.8 maximum aperture available at Jacaranta Digitech. Revamped optics yield higher resolution and improved sharpness over the previous generation. The focusing system has been replaced with a VXD (Voice-coil extreme-torque Drive) mechanism that achieves faster. 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″.
