From 17mm Perspectives to 70mm Expressions
Fast, Class-Leading 4.1x Zoom Ratio with Built-In VC
The 17-70mm F/2.8 Di III-A VC RXD (Model B070) is a fast-aperture standard zoom lens for APS-C mirrorless cameras. Engineered to deliver both a broad zoom range and excellent image quality, it achieves a 4.1x zoom ratio — class-leading(1) for an APS-C standard zoom lens — while maintaining a fast, constant maximum aperture of F2.8. The 17-70mm F2.8 VC includes VC (Vibration Compensation) and a fast, quiet AF system. With focus breathing and AF noise effectively suppressed, it is optimised for both stills and video shooting. Despite offering a class-leading zoom ratio and VC, it remains notably lightweight and compact — an outstanding choice for daily use as well as travel where minimising weight is essential. Excelling in close-up work, the lens achieves an MOD of just 0.19m (7.5in) at the wide end. Capture unique, expressive images across a wide variety of everyday scenes, from street photography to portraits.

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 (a full-frame equivalent of 25.5–105mm for Sony E, Nikon Z, and FUJIFILM X mounts), it achieves a 4.1x zoom ratio — class-leading 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 optical construction consists of 16 elements in 12 groups, effectively incorporating two LD (Low Dispersion), two GM (Glass Molded Aspherical), and one hybrid aspherical lens elements. This achieves high resolution and high contrast not only in the centre of the image but also in the corners and at the edges — combining sharp expression that clearly captures subject details with beautiful, soft bokeh to make the main subject stand out. * If your camera has a lens correction setting (e.g., "Lens Compensation" or similar), please ensure it is set to "ON" or "AUTO." |

Built-In VC — Stable Shooting for Stills and Video To maximise the lens's inherent high optical performance, the 17-70mm F2.8 VC is equipped with TAMRON's proprietary VC (Vibration Compensation) mechanism. The VC effectively mitigates image degradation caused by camera shake — which commonly occurs during handheld shooting at slow shutter speeds, for instance indoors, at twilight, or when capturing nightscapes. When shooting video, image stabilisation automatically provides optimal compensation for a wide range of shooting situations. |

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 — crucial when shooting moving subjects. The system also boasts excellent quietness, making it ideal for still photography in silent environments and for video shooting where operational noise is objectionable. * With the 17-70mm F2.8 VC for CANON RF and Nikon Z mounts, autofocus may become less responsive when tracking subjects during zooming in video shooting. * Operational sounds may be recorded in video depending on the shooting environment. |
Suppressed Focus Breathing — Natural, Seamless Video Expression
The 17-70mm F2.8 VC is engineered to suppress focus breathing — the phenomenon where the angle of view changes as the focus position shifts — allowing for natural and seamless video shooting even in scenes that require focus changes. Built to support stable, authentic video shooting across a variety of scenes, it incorporates VC specifically optimised for video and an extremely quiet AF system, making it highly suitable for both handheld shooting and scenes involving audio recording.

MOD of 0.19m (7.5in) for Amazing Close-Ups The 17-70mm F2.8 VC provides exceptional close-up shooting performance for a fast-aperture standard zoom lens, with an MOD (Minimum Object Distance) of 0.19m (7.5in) at the wide end and 0.39m (15.4in) at the telephoto end. This capability allows you to capture subjects at short distances and expands your creative expression — whether by creating greatly blurred backgrounds or by highlighting intricate details. The lens excels in a wide range of scenarios, from daily use such as tabletop photography and candid family snaps, to advanced portrait work. |

Lightweight and Compact Design for Superior Mobility Designed specifically for APS-C cameras, the 17-70mm F2.8 VC relentlessly pursues mobility. Despite offering a class-leading zoom ratio and VC, it is remarkably lightweight and compact — with a length of 119.3mm (4.7in), a weight of 525g (18.5oz), and a maximum diameter of ø74.6mm. This makes it extremely useful for daily use and as a travel lens, especially during hiking and other activities where bulk matters. * Length and weight are for Sony E-mount lens. |
