The world’s first 17-70mm F2.8, large aperture standard zoom lens for APS-C mirrorless cameras

The 17-70mm F/2.8 Di III-A VC RXD (Model B070) is a large aperture everyday zoom lens for Sony E-mount APS-C and Fujifilm-X mirrorless cameras. This lens was created to achieve a broad zoom range and excellent image quality. With a focal length range of 17-70mm (a full-frame equivalent of 25.5-105mm), it’s the world’s first F2.8 standard zoom lens with a 4.1x zoom ratio for APS-C cameras. The 17-70mm includes Tamron’s proprietary VC (Vibration Compensation). Additionally, this lens focuses very close. It features an MOD (Minimum Object Distance) of 0.19m (7.5 in) at the wide-angle end and 0.39m (15.4 in) at the telephoto end. When shooting very close to the subject, the lens enables expressive imagery with highly blurred backgrounds, a feature unique to large aperture lenses. From portrait to landscape, and your everyday life, this lens captures all of the excitement and discoveries with the finest possible detail.
