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

The Tamron 11-20mm f/2.8 Di III-A RXD is an ultra-wide-angle lens for Sony E full-frame cameras. The focal length lends itself well to shooting landscapes, astrophotography and architecture.

A bright aperture affords increased control over the depth of field for creating soft bokeh background details along with enhanced low-light performance.

The optical design incorporates one XLD element, two LD elements, and two glass-moulded aspherical elements to produce a highly corrected image with reduced chromatic aberrations and colour fringing for improved clarity and colour 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 15cm 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.

  • Sony E-Mount / ASP-C Format
  • 17-30mm (35mm Equivalent
  • Aperture Range: f/2.8 to f/16
  • 1x XLD, 2x GM Asph., and 2x LD Elements
  • Moisture-Resistant Construction

Moisture-resistant construction protects the lens under inclement conditions, and a fluorine coating on the front lens element protects against dust, dirt, and smearing.

The new 11-20mm f/2.8 zoom is the world's first ultra-wide-angle zoom lens for Sony E-mount APS-C mirrorless cameras that features an aperture of f/2.8. Despite its fast f/2.8 aperture, the lens is very small ( and feels perfectly balanced attached to a compact APS-C mirrorless camera body. It is the 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 MOD (Minimum Object 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 new zoom is protected by Moisture-Resistant Construction and Fluorine Coating in consideration of outdoor shooting. Its 67mm filter size is identical to TAMRON's 17-70mm F/2.8 Di III-A VC RXD (Model B070) fast-aperture standard zoom lens for Sony E-mount APS-C mirrorless cameras and TAMRON’s nearly all lenses 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 f/2.8 aperture lens.

The world's first f/2.8 ultra-wide-angle zoom lens for APS-C mirrorless cameras

The 11-20mm f/2.8 is a bona fide ultra-wide-angle zoom lens with an aperture of f/2.8 across the entire zoom range. Meanwhile, it is compact, lightweight and very practical. You can enjoy the unique and powerful world of ultra-wide-angle photography at the 11mm end (the full-frame equivalent of 16.5mm). Ideal for regular use, the 20mm focal length (the full-frame equivalent of 30mm) is well suited for casual snapshot photography such as street shooting. With its usefulness rooted in its compact, lightweight design and fast f/2.8 aperture, the 11-20mm f/2.8 provides an exciting shooting experience with greater freedom in diverse shooting situations.

Compact and lightweight for superior usability

The 11-20mm f/2.8 is only 86.2mm in length and weighs just 335g. For a fast-aperture f/2.8 ultra-wide-angle zoom lens, this is remarkably compact and light. When used with an APS-C mirrorless camera body, it enables photographers to enjoy a responsive image capture system without being hindered by the size or weight of the lens. It provides a comfortable user experience for still photography and for shooting video using a small tripod or gimbal stabiliser.

Outstanding optical performance

The 11-20mm f/2.8 construction includes 12 elements in 10 groups. Two precisely located GM (Glass Molded Aspherical) lens elements assure high resolution across the entire image, from edge to edge. In addition, the 11-20mm f/2.8 incorporates one XLD (eXtra Low Dispersion) and two LD (Low Dispersion) lens elements to produce sharp images with optical aberrations highly corrected. It also features the BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating that suppresses ghosting and flare to a minimum level and reveals the minute details of objects even when the subject is backlit. The combination of features harmonises to provide sharp images with natural colours and rich saturation.

MOD of 0.15m at the 11mm focal length

The 11-20mm f/2.8 boasts a MOD (Minimum Object Distance) of 0.15m (5.9 in) at the 11mm focal length setting and 0.24m at the 20mm end. This results 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 has an astonishing maximum magnification ratio of 1:4 that enables wide-angle macro photography that parlays the perspective unique to ultra-wide-angle lenses, while also leveraging the expressive bokeh provided by the fast, bright maximum aperture of this lens.

A user-friendly unified 67mm filter size across the series

The 11-20mm f/2.8 is so light that the total weight of it and the 17-70mm f/2.8 Di III-A VC RXD (Model B070) standard zoom lens for Sony E-mount APS-C mirrorless cameras together is only approximately 860g (30.3 oz). The combination of these two lenses covers an extreme range of focal lengths from 11mm to 70mm (equivalent to 16.5mm to 105mm on full-frame cameras) with a fast, wide-open aperture of F2.8 at every focal length, thereby enabling the size and weight of an entire mirrorless system to be massively reduced without sacrificing capabilities. Same as TAMRON's nearly all lens models for Sony E-mount cameras, it has a unified 67mm filter size that allows reciprocal sharing of filters such as PL and ND, and lens caps.
