Overview
Large aperture F/2.8 ultra wide-angle zoom lens for full-frame mirrorless
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.
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.
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.
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.
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.
