The 17-70mm F/2.8 Di III-A2 VC RXD (Model B070) is a fast-aperture everyday zoom lens for Sony E-mount and FUJIFILM X-mount APS-C mirrorless cameras. Fast, sharp, quiet, and small—this new APS-C zoom lens is extraordinarily versatile and perfect for everyday photography. The 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 17-70mm 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). When shooting video, by leveraging AI technology, image stabilization performs automatically to best compensate for different shooting situations. Designed specifically for use with APS-C mirrorless cameras, the lens is light weight and compact, even with VC. Its small size and versatility make it a great choice for outdoor, travel and vacation photography, where compact camera bags are preferred, and of course for daily use. The lens is equipped with TAMRON’s RXD (Rapid eXtra-silent stepping Drive) AF drive system, a high-speed, precision stepping motor unit with well controlled motor sound. Additionally, photographers / users can take advantage of a close working distance. 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. It also incorporates a wide variety of other features, including Moisture-Resistant Construction and Fluorine Coating for added durability. In your everyday life and on your trips to distant places, this lens captures all the excitement and discoveries with the finest possible detail.

Adding to the versatility of the zoom design is a Vibration Compensation image stabilization system, which reduces the appearance of camera shake for steadier photo and video recording in low-light conditions. Also benefitting handling, an RXD stepping motor enables quick, near-silent autofocus performance along with full-time manual focus override and a minimum focusing distance of 7.5″. Suiting this lens’s use in inclement weather conditions, it also features a moisture-resistant construction along with a fluorine-coated front element to protect against fingerprints and smudging.
