Tamron 17-28mm f2.8 DI RXD Lens for Sony E-Mount

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.
