Versatile 17-70mm Focal Length — Excellent in Every Shooting Scenario

The 17-70mm F/2.8 Di III-A VC RXD (Model B070) is a versatile zoom lens that lets you enjoy shooting in a multitude of genres, from wide-angle scenes to mid-telephoto moments. With a focal length range of 17mm to 70mm,2 it achieves a 4.1x zoom ratio, class-leading1 for an APS-C standard zoom lens. It's ideal for a wide variety of situations, from portraits and street photography to landscapes and architectural settings.

Constant F2.8 Aperture — Beautiful Bokeh and Exquisite Detail

The 17-70mm F2.8 VC maintains its fast F2.8 maximum aperture throughout the entire zoom range, ensuring optimal image quality even in dimly lit scenes. The lens’s optical construction consists of 16 elements in 12 groups. By effectively incorporating two LD (Low Dispersion), two GM (Glass Molded Aspherical), and one hybrid aspherical lens elements, the 17-70mm F2.8 VC achieves high resolution and high contrast not only in the center of the image but also in corners and at the edges. The lens successfully combines sharp expression that clearly captures subject details with the beautiful, soft bokeh needed to make the main subject stand out.

High Performance AF — Fast, Quiet, and Ready to Capture Decisive Moments

The AF system is equipped with TAMRON's proprietary RXD (Rapid eXtra-silent stepping Drive). RXD uses an actuator to precisely control the rotational angle of the motor, allowing it to directly drive the focusing lens without passing through a reduction gear. A sensor that precisely detects the position of the lens provides high-speed and accurate AF, which is crucial when shooting moving subjects. Furthermore, the system boasts excellent quietness, making it ideal for still photography in silent environments and for video shooting with audio capture where operational noise is objectionable.
