A lens as luminous as your creative vision
Step out of the normal lens zone and into the wilds of wide-angle. The 17-28mm F/2.8 Di III RXD (Model A046) is a large aperture ultra wide-angle zoom lens for Sony E-mount that was designed exclusively for mirrorless cameras and provides unrivalled portability and superb image quality. It’s the smallest and lightest weight zoom lens in its class. The dramatic 17-28mm zoom range adds new dimensions to photographing landscapes, cityscapes, mountains and scenic vistas—as well as groups and building interiors. Despite its compact size, it offers outstanding optical performance. Strategically deployed LD (Low Dispersion) and XLD (eXtra Low Dispersion) lens elements thoroughly suppress chromatic aberration. The combination of ultra wide-angle focal length and an MOD (Minimum Object Distance) of 0.19m (7.5 in) at the wide-angle end encourages richly expressive and creative photography. The new 17-28mm zoom’s AF drive system is powered by the RXD (Rapid eXtra-silent stepping Drive) stepping motor unit that enables it to deliver high-speed, high-precision operation. In addition, the new zoom lens features Moisture-Resistant Construction and a hydrophobic Fluorine Coating that repels fingerprints and dirt. 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; that paved the way for a surprisingly small size—just 99mm (3.9 in) long, weighing but 420g (14.8 oz). The overall length of the lens does not change during zooming, thereby offering consistent handling and stable shooting operations. In addition, the Φ67mm 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 zoom lens in the series, the 28-75mm F/2.8 Di III RXD (Model A036). This means the same filters such as PL (Polarizer), lens caps and other accessories may be used for both 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.
Superior close-up shooting performance empowers creativity
The 17-28mm zoom features an MOD of 0.19m (7.5 in) 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 in) 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 new 17-28mm zoom lets you shoot a video without worrying about picking up ambient drive sounds.
Built with Mirrorless in mind
The The Model A046 achieves an astonishingly small diameter for a high-speed ultra wide-angle zoom lens, as witnessed by its modest 67mm filter size. Its unprecedented light weight and compact size provide excellent balance when used with a full-frame mirrorless camera, making it easy to carry, and enabling it to cater to a wide range of scenes and shooting conditions.
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
* Features vary by camera. Please consult your camera’s instruction manual for details.
Circular Aperture to Produce a Smooth-Edged Bokeh
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 light spots.
Fluorine Coating for protection and safe cleaning
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.
Moisture-Resistant Construction protects your lens
For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment.
Superb corner-to-corner image quality from an ultra-wide-angle zoom
The Model A046 offers a fast F/2.8 aperture throughout the entire zoom range, and delivers high-resolution and contrast edge to edge. The combination of ultra wide-angle focal length, fast constant F/2.8 aperture and an MOD (Minimum Object Distance) of 0.19m (7.5 in) at the wide-angle end encourages richly expressive and creative photography in a multitude of scenarios.
Rapid eXtra-silent stepping Drive
The Model A046’s AF drive system is powered by the RXD (Rapid eXtra-silent stepping Drive) stepping motor unit, enabling it to deliver high-speed, high-precision and superbly quiet operation suitable for shooting video as well as still photographs.
Versatile, exciting combination when paired with the 28-75mm F/2.8 Di III RXD (Model A036)
Two high-performance partners, the 17-28mm zoom combined with the 28-75mm zoom, cover the super-broad range from 17mm ultra wide-angle to 75mm medium telephoto, and maintain excellent speed with an open aperture of F/2.8. The total weight of the two lenses is less than 1kg (35.3 oz)*. Similar in design and operation, both lenses have the zoom ring at the front while the focus ring is at the rear, so you can seamlessly concentrate on shooting after exchanging lenses. And since both models have the same filter diameter of 67mm, filters such as PL (Polarizer), lens caps and other accessories are compatible with both. This compact but potent combo makes the most of the mobility of mirrorless cameras.
*Model A036: 550g (19.4 oz), Model A046: 420g (14.8 oz)
User-friendly design is beautiful, durable and functional
The 17-28mm zoom design is not only beautiful, it is functional as well and features an outer housing hugging the smooth contours of the lens body, deftly worked Luminous Gold brand ring and the precise, rigid metal lens mount. The Luminous Gold brand ring solidifies the characteristic look of a Tamron-branded lens whether on its own or attached to a camera body.
