Tamron 17-70mm f/2.8 Di III-A VC RXD (Nikon Z)

Tamron 17-70mm f/2.8 Di III-A VC RXD, model B070, is a fast standard zoom lens designed for APS-C mirrorless cameras, available for Sony E, Fujifilm X, Nikon Z, and Canon RF mounts. The 17-70 mm focal range corresponds to approximately 25.5-105 mm in full-frame format, providing versatile coverage from moderate wide-angle to short telephoto, suitable for travel, reportage, environmental portraiture, everyday photography, landscape, video content, and hybrid photo/video use. The constant f/2.8 maximum aperture allows the same exposure to be maintained throughout the zoom range and provides good depth-of-field control compared with slower standard zoom lenses. The VC, Vibration Compensation, system integrates Tamron optical stabilization, useful for handheld shooting and less favorable lighting conditions, while the RXD, Rapid eXtra-silent stepping Drive, motor manages autofocus with smooth and quiet operation, suitable also for video recording. The optical design consists of 16 elements in 12 groups, with a circular 9-blade diaphragm, a minimum focusing distance of 0.19 m at the wide end and 0.39 m at the telephoto end, a maximum magnification ratio of 1:4.8 at wide angle and 1:5.2 at telephoto, and a 67 mm filter thread. With an indicative weight of approximately 525 g in the Sony E version and dimensions of about 74.6 × 119.3 mm, Tamron 17-70mm f/2.8 Di III-A VC RXD is suitable for APS-C users looking for a single stabilized and bright lens suitable for many shooting situations without frequently changing lenses.
