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.
Rapid eXtra-silent stepping Drive
The
RXD stepping motor unit is exceptionally quiet and perfect for video use.
Durable Construction
Moisture-Resistant
Construction and Fluorine Coating provide extra protection.

with many camera-specific features and functions, including Fast Hybrid AF and
