Tamron 11-20mm F/2.8 Di III-A2 RXD Lens is a fast-aperture ultra wide-angle zoom lens for Sony E mount APS-C mirrorless cameras. It features the world's first f/2.8 maximum aperture for Sony E mount APS-C mirrorless in this category and has a compact and lightweight design.
This ultra-wide lens is particularly suitable for landscape, astrophotography, and architectural shooting. Its bright f/2.8 constant maximum aperture complements this range and affords increased control over depth of field along with enhanced low-light performance.
The optical design incorporates one XLD element, two LD elements, and two glass-molded aspherical elements to produce a highly corrected image with reduced chromatic aberrations and color fringing for improved clarity and color accuracy. Individual elements also feature Tamron's BBAR coating, which suppresses flare and ghosting for greater contrast when working in backlit and harsh lighting conditions. A responsive RXD stepping drive motor enables quick, near silent autofocus performance to suit stills and video.
The minimum object distance is just 5.9" at the widest end of the zoom range, unlocking powerful wide-angle macro shooting capability with a unique perspective that makes near objects look larger, and distant objects smaller. Additionally, the f/2.8 maximum aperture produces a shallower depth-of-field that creates soft bokeh background details. Moisture-resistant construction protect the lens under inclement conditions, and a fluorine coating on the front lens element protects against dust, dirt, and smearing.
