Tamron 17-70mm F2.8 DI III-A VC RXD for Sony



The Tamron 17-70mm F2.8 Di III-A RXD Sony E-Mount (APS-C) is a versatile everyday zoom lens designed for Sony APS-C cameras. It offers a broad zoom range and an impressive F2.8 maximum aperture, ensuring excellent image quality. Additionally, it boasts a minimum object distance of 0.19m at the wide-angle and 0.39m at the telephoto end, allowing expressive images with beautifully blurred backgrounds. Moreover, the lens is compact and lightweight, highly portable for various shooting situations. Furthermore, it incorporates Tamron’s proprietary VC (Vibration Compensation) technology with AI, providing stable video footage for smooth and professional results.

Key Features:

  • Constant f/2.8 maximum aperture for consistent brightness and depth of field control.
  • Aspherical elements correct distortion and spherical aberrations, ensuring sharpness and accurate rendering.
  • Additionally, LD (Low Dispersion) elements minimize color fringing and chromatic aberrations, improving clarity and color accuracy.
  • For superior optical performance, BBAR Coating suppresses internal reflections, flare, and ghosting, delivering greater contrast and color fidelity, especially in strong lighting conditions.
  • The lens’ autofocus system is driven by the RXD autofocus motor, providing quick, quiet, and smooth focusing performance. Plus, it offers a minimum focusing distance of 19cm and maximum magnification of 1:4.8 for stunning close-up shots.
  • To ensure steady shots, even in difficult lighting conditions, VC image stabilization reduces the appearance of camera shake for handheld shooting.
  • Lastly, the lens’ moisture-resistant construction and fluorine coating add durability, protecting against dust, dirt, and smearing.



The lens offers outstanding optical performance with its 17-70mm focal length range, equivalent to 25.5-105mm on full-frame cameras, and a 4.1x zoom ratio. The optical construction includes 16 elements in 12 groups, with GM and hybrid aspherical lens elements meticulously arranged to maintain high-resolution performance from edge to edge.

For worry-free photography and video capture, VC image stabilization ensures clear and steady shots. Additionally, the RXD stepping motor enables both high-speed and accurate AF, even when capturing moving subjects, making it perfect for dynamic photography and videography.

Despite its impressive features, the 17-70mm F2.8 zoom remains highly portable, measuring only 119.3mm in length and 74.6mm in maximum diameter, with a weight of just 525g. This makes it an ideal everyday zoom lens for various situations, offering photographers high image quality with the benefits of a large F2.8 aperture.
