Lens Overview
Large aperture F2.8 ultra-wide-angle zoom lens for full-frame mirrorless
The 17-28mm F/2.8 Di III RXD (Model A046) is an ultra wide-angle zoom lens for Sony E-mount mirrorless cameras, covering a dramatic 17-28mm range, adding new dimensions to photographing landscapes, cityscapes, mountains, scenic vistas, groups, and building interiors. Despite its compact size, it delivers outstanding optical performance, suppressing chromatic aberration effectively. The combination of an ultra wide-angle focal length and an MOD of 0.19m (7.5″) at the wide end encourages richly expressive and creative photography. The lens’s AF drive system, powered by the RXD stepping motor unit, delivers high-speed, high-precision operation. This compact but powerful tool will boost your mobility and enhance your ability to capture subjects in new and imaginative ways, making it an excellent addition to your photographic toolkit.
A Lens That Matches the Brilliance of Your Creative Vision
Step out of the normal lens zone and into the wilds of wide-angle with the 17-28mm F/2.8 Di III RXD (Model A046), a large aperture ultra-wide-angle zoom lens for Sony E-mount that provides unrivalled portability and superb image quality. It’s the smallest and lightest weight zoom lens in its class,
yet offers outstanding optical performance and it 7.5 in. MOD at the wide end encourages richly expressive and creative photography. This compact but powerful tool will boost your mobility and drive your vision of capturing subjects in new ways.
Compact size you can take anywhere—and everywhere
TAMRON makes large aperture ultra wide-angle photography more exciting, and for this lens we focused on usability. The 17-28mm zoom range was carefully selected, paving the way for a surprisingly small size—just 99mm (3.9″”) long, weighing but 420g (14.8oz). The overall length of the lens does not change when zooming, offering consistent handling and stable shooting operation. And the Ø67mm filter size is small for a large aperture ultra wide-angle zoom lens. Plus, it shares the same filter diameter as the high-speed standard and telephoto zoom lenses in the series, the 28-75mm F/2.8 Di III VXD G2 (Model A063) and 70-180mm F/2.8 Di III VC VXD G2 (Model A065). This means the same filters such as circular polarizers, lens caps and other accessories may be used for all three models.
Beautifully capture every scene and vista
The 17-28mm zoom provides magnificent image quality without compromise despite its compactness. Two LD lens elements and one XLD element (which has properties close to fluorite) are precisely located to quash chromatic and other aberrations. In addition, the BBAR (Broad-Band Anti-Reflection) Coating applied to lens surfaces reduces ghosting and flare that are otherwise likely to occur when shooting against the sunset’s glow and other backlit situations. Leveraging camera functions*, it provides excellent optical performance matching the latest high resolution image sensors from edge-to-edge throughout the entire zoom range. The 17-28mm zoom invites you into the breathtaking world of ultra wide-angle photography.
*When shooting with the camera’s lens correction function enabled.
Superior close-up shooting performance empowers creativity
The 17-28mm zoom features an MOD of 0.19m (7.5″”) at the wide 17mm end, rendering a maximum magnification ratio of 1:5.2. At the tele end, the MOD is 0.26m (10.2″”) and the maximum magnification ratio is 1:6. In short, you can easily get close enough for a powerful shot. Your images can emphasize the perspective unique to ultra wide-angle lenses, and you can produce soft expressions with a shallow depth of field distinctive to large aperture lenses by opening the aperture and getting close to the subject. Versatile, functional and sensational—all at the same time.
High performance autofocus system means you'll own every shooting opportunity
The AF drive on the 17-28mm zoom 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 accurately detects the position of the lens enables high-speed and precise AF, which is ideal when shooting continually moving subjects or recording video. Perfect for street shooting and grab shots of groups of friends. And with a focusing system that is both smooth and quiet, the 17-28mm zoom lets you shoot a video without worrying about picking up ambient drive sounds.
Built with Mirrorless in Mind
TAMRON’s new 17-28mm zoom is compatible with many of the advanced features that are specific to mirrorless cameras. This includes:
– Fast Hybrid AF
– Eye AF
– Direct Manual Focus (DMF)
– In-camera lens correction (shading, chromatic aberration, distortion)
– Camera-based lens unit firmware updates

Lens Tour
Circular Aperture
A 9-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background highlights.

The application of BBAR (Broad-Band Anti-Reflection) Coating for suppressing reflections on lens element surfaces minimizes unwanted flare and ghosting to deliver sharp, crisp, high-contrast images.
For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment.
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellent. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.
