World’s first high-speed standard zoom lens for APS-C cameras with the focal length range of 17-70mm 4.1x zoom ratio
The Model B070 has a focal length range of 17-70mm, equivalent to 25.5-105mm on full-frame cameras. It is the first F2.8 high-speed zoom lens in the world for APS-C mirrorless cameras to achieve a 4.1x zoom ratio.
Outstanding optical performance
The optical construction of the new 17-70mm F2.8 features 16 elements in 12 groups. Two GM (Glass Molded Aspherical) lens elements and one hybrid aspherical lens element are precisely arranged to maintain high-resolution performance from edge to edge.
Upgraded VC effective in combination with Sony APS-C mirrorless cameras, leveraging AI for video shooting
The 17-70mm F2.8 features Tamron's proprietary VC mechanism. Additional sophisticated algorithms optimized for this model and a dedicated, independently operating MPU all combine to superbly compensate for vibration. This feature is available when the lens is used with cameras with or without in-body image stabilization. When shooting video, by leveraging AI technology, image stabilization performance improves compared to conventional models.
Close focusing−MOD is just 0.19m (7.5 in) at wide-angle end
The 17-70mm F2.8 zoom focuses close, down to 0.19m (7.5 in) MOD (Minimum Object Distance). This is far superior to the performance achieved by conventional high-speed zoom lenses for APS-C cameras. In addition, the 0.39m (15.4 in) MOD at the 70mm telephoto end ensures good close-range shooting performance allowing photographers to enjoy compelling close-up shots.
A highly portable compact design
The 17-70mm F2.8 zoom measures a scant 119.3mm (4.7 in) in length and 74.6mm in maximum diameter and weighs only 525g (18.5 oz). This is remarkable for a lens with built-in VC image stabilization. When used with Sony's APS-C mirrorless cameras, this zoom is nicely balanced and provides a comfortable user experience.
The RXD (Rapid eXtra-silent stepping Drive) stepping motor unit is exceptionally quiet and perfect for video use. Moisture-Resistant Construction and Fluorine Coating provide extra protection. Compatible with many camera-specific features and functions, including Fast Hybrid AF and Eye AF
