The world's first1 17-70mm F2.8, fast-aperture standard zoom lens for APS-C mirrorless cameras
The 17-70mm F/2.8 Di III-A2 VC RXD (Model B070) is a fast-aperture everyday zoom lens for Sony E-mount and FUJIFILM X-mount APS-C mirrorless cameras. Fast, sharp, quiet, and small—this new APS-C zoom lens is extraordinarily versatile and perfect for everyday photography. The lens was created to achieve a broad zoom range and excellent image quality. With a focal length range of 17-70mm (a full-frame equivalent of 25.5-105mm), it's the world's first 17-70mm F2.8 standard zoom lens with a 4.1x zoom ratio for APS-C cameras. The 17-70mm includes TAMRON's proprietary VC (Vibration Compensation). When shooting video, by leveraging AI technology, image stabilization performs automatically to best compensate for different shooting situations. Designed specifically for use with APS-C mirrorless cameras, the lens is light weight and compact, even with VC. Its small size and versatility make it a great choice for outdoor, travel and vacation photography, where compact camera bags are preferred, and of course for daily use. The lens is equipped with TAMRON's RXD (Rapid eXtra-silent stepping Drive) AF drive system, a high-speed, precision stepping motor unit with well controlled motor sound. Additionally, photographers / users can take advantage of a close working distance. It features an MOD (Minimum Object Distance) of 0.19m (7.5 in) at the wide-angle end and 0.39m (15.4 in) at the telephoto end. It also incorporates a wide variety of other features, including Moisture-Resistant Construction and Fluorine Coating for added durability. 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.
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.
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 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.

Optical Construction (16 elements in 12 groups)
MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures.
The closer the 10 lp/mm (line pairs per millimeter) curve (the thick line for low frequency) in an MTF chart to "1" of the vertical axis (the higher up), the higher the contrast reproduction performance of the tested lens will be. The closer the 30 lp/mm curve (the thin line for high frequency) to "1" (the higher up), the higher the resolving power and thus the subjective sharpness of the lens will be.
Lens performance differs depending upon directions. Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance.
Performance characteristics of photographic lenses cannot be expressed with only MTF charts. There are other factors that are expressed in different methods, such as taste of softness and degrees of compensation of various aberrations. But you can use MTF charts as a scale to measure lens performance.
