Large aperture F/2.8 ultra wide-angle zoom Lens for full frame Mirrorless Cameras
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. (ref. animation for zooming) 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 mod

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.
