The Tamron 17-70mm F/2.8 Di III-A VC RXD (Model B070) is a fast everyday zoom lens for Sony E-mount and FUJIFILM X-Mount APS-C mirrorless cameras. Sharp, quiet, and small—this APS-C zoom lens is extraordinarily versatile and perfect for everyday photography. With a focal length range of 17-70mm (25.5-105mm full-frame equivalent), it’s the world's first 17-70mm F2.8 standard zoom lens with a 4.1x zoom ratio for APS-C cameras. The lens was created to achieve a broad zoom range and excellent image quality. It is a small, lightweight lens that is also equipped with Tamron's VC (Vibration Compensation) mechanism to minimize camera shake. When shooting video, by leveraging AI technology, image stabilization performance improves compared to conventional models. The lens features Moisture-Resistant Construction, Fluorine Coating and a Ø67mm filter size – the same as the Tamron series of lenses for full-frame mirrorless cameras. Designed specifically for use with APS-C mirrorless lens cameras, it is light weight and compact, even with VC image stabilization and a host of other user-friendly features.
Focal length of 17-70mm for shooting in a broad range of situations
This versatile zoom lens lets you enjoy shooting in a multitude of genres, from wide-angle scenes to telephoto moments. With a focal length range of 17mm to 70mm (a full-frame equivalent of 25.5-105mm), this is the world's first large aperture F2.8 standard zoom lens for APS-C mirrorless cameras to achieve a 4.1x zoom ratio. It’s ideal for a variety of scenarios, from portraits and street snapshots, to landscapes and even close-ups.
Fast F2.8 aperture throughout the entire zoom range for Sony E-mount and FUJIFILM X-mount
The 17-70mm F2.8 maintains its fast F2.8 maximum aperture throughout the entire zoom range (unlike variable aperture lenses where the maximum aperture changes as you zoom). Thanks to the F2.8 and high optical performance, the 17-70mm F2.8 allows you to capture your subjects with clear details from wide-angle to telephoto. The three main advantages of a fast F2.8 aperture are: A) ability to shoot successfully in lower light levels, B) beautiful and dreamy bokeh, and C) better control of depth-of-field which is particularly useful when intentionally limiting depth-of-field to improve portraits by blurring the area behind the main subject. Structurally, the optical formula includes 16 elements in 12 groups. It was created in pursuit of superior optical performance, utilizing an effective allocation of two GM (Glass Molded Aspherical) lens elements and one aspherical hybrid lens element. The optical design ensures high resolution and high contrast not just in the center of the image but also in corners and at the edges.
TAMRON’s proprietary VC for stable photography and video shooting
The 17-70mm F2.8 utilizes TAMRON's highly regarded VC image stabilization system to maximize the inherent optical performance of the lens. It reduces the degradation of picture quality caused by minute camera shake that is likely to occur during hand-held shooting at slow shutter speeds under low-light conditions indoors or at dusk. When shooting video, image stabilization leveraging AI technology will automatically perform the best compensation for different shooting situations.
Focuses close – MOD of 0.19m (7.5 in) at the wide-angle end
This advanced lens focuses extremely close for a standard zoom lens for APS-C mirrorless cameras. The MOD (Minimum Object Distance) is just 0.19m (7.5 in) at the wide-angle end and 0.39m (15.4 in) at the telephoto end. When shooting very close to the subject, the lens enables expressive imagery with highly blurred backgrounds, a feature unique to large-aperture lenses. This allows you to create one-of-a-kind photo of a variety of subjects, from snapshots to portraits, landscapes and even architectural photography. Close-up shots of scenery taken at the 17mm end maximize the unique perspective only true wide-angle lenses can deliver.
