The Tamron 11-20mm F/2.8 Di III-A RXD Sony E APS-C is a fast-aperture ultra wide-angle zoom lens for Sony E-mount APS-C mirrorless cameras. It is the world's first ultra wide-angle zoom lens for Sony E-mount APS-C mirrorless cameras that features an aperture of F2.8.
Despite its fast F2.8 aperture, this lens is very small at 86.2.mm and feels perfectly balanced attached to a compact APS-C mirrorless camera body. This makes for an ideal ultra wide-angle lens for regular use.
At the 11mm ultra wide-angle end, the lens exhibits stunning close-range shooting performance, achieving a minimum focus distance of 0.15m and a maximum magnification ratio of 1:4. This feature invites wide-angle macro shooting that exploits the creative effects of naturally occurring distortion that only ultra wide-angle lenses can provide.
The Tamron 11-20mm F/2.8 Di III-A RXD Sony E APS-C lens is protected by Moisture-Resistant Construction and Fluorine Coating in consideration of outdoor shooting. Its 67mm filter size is identical to nearly all of TAMRON’senses in the series of full-frame mirrorless cameras that sit nicely on APS-C cameras as well.
Compatible with many of the features that Sony builds into its cameras, including Fast Hybrid AF and Eye AF, the lens is packed with features that support comfortable shooting. The highly practical features enable photographers to enjoy the superb image quality of this ultra wide-angle, fast F2.8 aperture lens.
The 11-20mm F2.8 is a bona fide ultra wide-angle zoom lens with an aperture of F2.8 across the entire zoom range and its advanced optical construction includes 12 elements in 10 groups plus BBAR-G2 Coating for images with natural colours and rich saturation with highly corrected optical aberrations.
The 11-20mm F2.8 boasts a mimimum focus distance of 0.15m at the 11mm focal length setting and 0.24m at the 20mm end. Resulting in better and more versatile close-range shooting performance than existing ultra wide-angle zoom lenses at their widest focal length.
At the widest 11mm setting it also has an astonishing maximum magnification ratio of 1:4 that enables wide-angle macro photography with the unique perspective of ultra wide-angle lenses, while also leveraging the expressive bokeh provided by the fast, bright maximum aperture.
The 11-20mm F2.8 is only 86.2mm in length and weighs just 335g making it remarkably compact and light for a fast-aperture F2.8 ultra wide-angle zoom lens. When used with an APS-C mirrorless camera body, this enables you to enjoy a responsive image capture system without being hindered by the size or weight of the lens.
Same as TAMRON's nearly all lens models for Sony E-mount cameras, it has a unified 67mm filter. This allows almost your whole Tamron lens collection to share filters such as PL and ND, and not to mention makes lens caps a breeze.
