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. Versatile standard zoom is designed for full-frame Nikon Z-mount mirrorless cameras but can also be used with APS-C models, where it will provide a 42-112.5mm equivalent focal length range. Bright constant f/2.8 maximum aperture affords consistent illumination throughout the zoom range and also affords greater control over the depth of field for working with selective focus techniques.VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism provides fast, quiet, and precise autofocus performance throughout the zoom range. The connector port works in conjunction with Tamron Lens Utility software for customizing lens functions and updating firmware through the lens rather than through the camera.
