Lens Overview
Compact, lightweight F2.8 ultra wide-angle zoom lens for APS-C mirrorless invites new experiences
The 11-20mm F/2.8 Di III-A RXD (Model B060) is an ultra wide-angle zoom lens for Sony E and FUJIFILM X-mount APS-C mirrorless cameras (and coming soon for Canon RF), offering a bright constant F2.8 aperture and outstanding portability. The fast aperture lets you maintain a high shutter speed even in dark conditions, ensuring sharp handheld images with minimal shake. Special lens elements are arranged to suppress optical aberrations, producing clear images and high-resolution performance throughout the zoom range. The lens is so lightweight and compact that it’s ideal for everyday use and travel and is perfect for video, especially when using a gimbal. It provides a remarkable MOD allowing you to close in on subjects easily. The fast precision AF drive system is perfect for still and video shooting. Moisture-Resistant Construction and Fluorine Coating offer additional protection when shooting outdoors. This lens combines excellent portability with the ability to capture unique images, expanding your enjoyment of photography.
Capture Dynamic Images with a Fast-Aperture Ultra Wide-Angle Zoom Lens
Covering focal lengths from 11-20mm (a full-frame equivalent of 16.5-30mm), this ultra wide-angle lens for APS-C mirrorless cameras features a maximum aperture of F2.8 and allows users to fully enjoy the distinctive depth-of-field and unique perspective provided by an ultra wide-angle lens. Enjoy a higher degree of photographic freedom than ever before, such as taking regular snapshots at the 20mm end, which has a rather natural angle of view,
and then zooming out to take powerful ultra wide-angle shots of landscapes or selfies at the wide end – all while enjoying the easy handling, creamy bokeh and other advantages that fast-aperture lenses offer. The lens shines in various scenarios, including architecture, landscape, indoor environmental portraits, travel, interior photography, and video.
A design so compact and lightweight, it’s hard to believe it’s an ultra wide-angle lens
The lens was designed to be exceptionally compact and lightweight, an ideal match with APS-C mirrorless cameras. It has an overall length of 86.2mm (3.4″)*, and weighs only 335g (11.8oz). Imagine a lens so small and light that it is hard to believe it’s a full-fledged fast-aperture ultra wide-angle zoom. You can concentrate on shooting without worrying about bulk or weight. When used with a compatible APS-C mirrorless camera body, you’ll enjoy carefree handheld shooting of still images and find it comfortable to shoot video even when using a compact tripod or gimbal.

Enjoy outstanding ultra wide-angle optical performance of the TAMRON 11-20mm F2.8
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 (5.9")
The MOD (Minimum Object Distance) is just 0.15m (5.9″) at the wide 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. Additionally, using the F2.8 maximum aperture produces a shallower depth-of-field that creates soft bokeh in the background, allowing users to take distinctive images with unique expressions.
High performance RXD autofocus operates quietly and accurately captures subjects when shooting both still and video
The AF drive on the 11-20mm F2.8 includes an RXD motor unit to help you stay focused on the action. RXD uses an actuator to precisely control the rotational angle of the motor, allowing it to directly drive the focusing lens without passing through a reduction gear. A sensor that precisely detects the position of the lens enables high-speed and accurate AF, which is ideal when shooting continually moving subjects or recording video. And with a focusing system that is both smooth and quiet, the 11-20mm F2.8 lets you shoot free from stress not worrying the drive sound in a quiet environment.
Built with Mirrorless in Mind
TAMRON’s new 11-20mm F2.8 is compatible with many of the advanced features that are specific to mirrorless cameras. These includes:
– Fast Hybrid AF
– Eye AF
– Direct Manual Focus (DMF)
– In-camera lens correction (shading, chromatic aberration, distortion)
– Camera-based lens unit firmware updates

Lens Tour
Circular Aperture
A 9-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background highlights.
Features
A 7-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background highlights.
TAMRON has long been an innovator of coating technologies that prevent ghosting and flare. Second-generation BBAR-G2 Coating is a groundbreaking advancement that provides vastly improved performance compared to the original BBAR (Broad-Band Anti-Reflection) Coating. The coating corrects for ghosting and flare to an unprecedented extent and renders fine subject detail with true clarity and stunning contrast even under backlit conditions.
For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment.
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellent. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.
