The Tamron 11-20mm f/2.8 Di III-A RXD Lens for Sony E-mount APS-C mirrorless cameras is a fast-aperture ultra wide-angle zoom lens designed for photographers and content creators seeking exceptional image quality in a compact and lightweight design. Offering a versatile 11-20mm focal length (16.5-30mm equivalent in 35mm format) with a constant f/2.8 maximum aperture, it delivers outstanding low-light performance, creative depth-of-field control, and consistent exposure throughout the zoom range.
Its advanced optical construction features one XLD (eXtra Low Dispersion) element, two LD (Low Dispersion) elements, and two glass-molded aspherical elements to effectively minimize chromatic aberrations, distortion, and color fringing while maintaining excellent sharpness and color accuracy across the frame. Tamron’s BBAR-G2 coating further reduces flare and ghosting, producing high-contrast images even when shooting into strong light sources.
Powered by Tamron’s Rapid eXtra Silent Stepping Drive (RXD) autofocus motor, the lens provides fast, accurate, and nearly silent autofocus performance, making it ideal for both still photography and video recording. The lens also offers an impressive minimum focusing distance of just 5.9 inches (15cm) at the wide end, allowing dramatic wide-angle close-up photography with enhanced perspective and attractive background blur.
Built for reliability in demanding environments, the lens features weather-sealed, moisture-resistant construction along with a fluorine-coated front element that resists water, fingerprints, dust, and smudges for easier maintenance. Its lightweight design makes it an excellent companion for travel, landscape photography, architecture, astrophotography, vlogging, and everyday creative shooting.
