Tamron 17-70mm f/2.8 Di III-A VC RXD Lens (FUJIFILM X)

Expand your photo experience with an advanced standard zoom lens

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. 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. In your everyday life and on your trips to distant places, this lens captures all the excitement and discoveries with the finest possible detail.

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 fast-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.

Your key to beautiful, brilliant video shooting

The 17-70mm F2.8 is a standard zoom lens that's ideal for not only still photography but also for video shooting. The 17-70mm F2.8 has minimal focus breathing, an undesirable phenomenon in which the angle of view changes depending on the focusing distance during videography. By counteracting focus breathing, the 17-70mm F2.8 empowers users' expression of their creative intentions to the fullest degree. In addition, the quiet RXD AF drive motor and the VC image stabilization mechanism facilitate hand-held video shooting.

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.

MOD of 0.19m (7.5 in) for amazing close-ups

This advanced lens focuses extremely close for a standard zoom lens for APS-C mirrorless cameras. The MOD 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 fast-aperture lenses. This allows you to create one-of-a-kind photos of a variety of subjects, from snapshots to portraits, landscapes, and even architectural photography. Close-up shots of your main subjects taken at the 17mm end maximize the unique perspective only true wide-angle lenses can deliver.

Compact, lightweight design is perfect match for APS-C mirrorless cameras

This lens was created through the uncompromising pursuit of portability optimized for use with APS-C Sony E-mount and FUJIFILM X-Mount cameras. Even with the inclusion of high-performance VC, the 17-70mm F2.8 is extremely light weight and compact, with an overall length of just 119.3mm (4.7 in), maximum diameter of 74.6mm, and weight of 525g (18.5 oz) *3. It is a very versatile lens for travel, where small bags are preferred, and is a great portable lens for daily use.

*3 Length and weight are based on the Sony-mount lens.

High performance autofocus system means you'll own every shooting opportunity

The AF drive on the 17-70mm F2.8 includes an RXD motor unit to help you stay focused on the action. 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 enables high-speed and accurate AF, which is ideal when shooting continually moving subjects or recording video. And with a focusing system that is both smooth and quiet, the 17-70mm F2.8 lets you shoot free from stress not worrying about the drive sound in a quiet environment.
