Tamron 11-20mm f/2.8 Di III-A RXD Lens for Sony E Mount

Offering the unprecedented brightness of constant F2.8 and outstanding portability, the 11-20mm F/2.8 Di III-A2 RXD (Model B060) is a fast-aperture ultra wide-angle zoom lens for Sony E-mount APS-C mirrorless cameras.

The lens is so light weight and compact that it is hard to believe it is a fast-aperture ultra wide-angle zoom lens. This makes it ideal for regular use, and for travel when you want to carry a smaller camera bag.

The lens also incorporates a fast precision AF drive system with an RXD (Rapid-eXtra-silent stepping Drive) stepping motor unit. Moisture-Resistant Construction and Fluorine Coating join forces to offer additional protection when shooting outdoors.

The 11-20mm F2.8 is a high-resolution lens that focuses on superb image quality as a full-fledged fast-aperture ultra wide-angle zoom. The optical construction includes 12 elements in 10 groups. High resolution performance is maintained across the entire frame with the well-balanced arrangement of two GM (Glass Molded Aspherical) lens elements. Two LD (Low Dispersion) and one XLD (eXtra Low Dispersion) lens elements are used to suppress the chromatic aberrations that tend to occur when shooting at the wide-open aperture of fast-aperture lenses. These features combine to render clear, crisp images. In addition, the use of the lens correction features built into Sony cameras lets users harness extra lens performance gains.

Indulge in the exciting world of wide-angle macro with an MOD of 0.15m

The MOD (Minimum Object Distance) is just 0.15m (5.9 in) at the widest end. This extreme close-range shooting performance allows you to get as close to a subject as you like. The maximum magnification ratio is 1:4 (an astonishing feat for an ultra wide-angle lens) and it unlocks powerful wide-angle macro shooting utilizing the unique perspective that makes near objects look larger, and distant objects smaller.
