You’ll be amazed from the very first shot
The world's first fast-aperture F2.8 ultra wide-angle zoom lens for mirrorless invites new experiences
Offering the unprecedented brightness of constant F2.8 and outstanding portability, the 11-20mm F/2.8 Di III-A RXD (Model B060) is a fast-aperture ultra wide-angle zoom lens for Sony E and FUJIFILM X-mount APS-C mirrorless caneras. Since the fast F2.8 aperture lets you maintain a high shutter speed even when shooting in dark conditions, you can capture sharp images handheld with minimal shake. Also, special lens elements have been optimally arranged to suppress optical aberrations. These features combine to produce clear images and high-resolution performance throughout the zoom range. The lens is so lightweight and compact that it is hard to believe it is a fast-aperture ultra wide-angle zoom lens. This makes it ideal for everyday use, and for travel when you want to carry a smaller camera bag. The 11-20mm F2.8 achieves an MOD (Minimum Object Distance) of 0.15m (5.9 in) at the widest end and 0.24m (9.4 in) at the 20mm end, ensuring the ability to close in on subjects as you please. The lens also incorporates a fast precision AF drive system with an RXD (Rapid eXtra-silent stepping Drive) stepping motor unit which is perfectly fit for still and video shootings. Moisture-Resistant Construction and Fluorine Coating join forces to offer additional protection when shooting outdoors. Everything you see, from daily life to travels, is within your photographic grasp with this lens. The 11-20mm F2.8 will expand your enjoyment of shooting by combining excellent portability with the ability to capture images unique to fast-aperture ultra wide-angle lenses.

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 challenging yourself to take powerful ultra wide-angle shots 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 and interior photography.

A design so compact and light weight, 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 in), and weighs only 335g (11.8 oz). 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 the outstanding 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
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. 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.

Explore a wide variety of situations by combining two lenses in TAMRON's series of fast-aperture zooms for APS-C mirrorless cameras
By combining the 11-20mm F2.8 and its balance of excellent portability and high image quality with the 17-70mm F/2.8 Di III-A VC RXD (Model B070), these two lenses cover an extreme range of focal lengths from 11mm to 70mm (a full-frame equivalent of 16.5mm to 105mm) with a fast, wide-open aperture of F2.8. The combined weight of the two lenses is only approximately 860g (30.3 oz). Drastically reducing bulky size and weight is advantageous during shooting and transportation and is convenient during travel when you want to lighten the load of your camera bag. Additionally, like most of the TAMRON's other lenses for mirrorless cameras, the filter size is standardized at 67mm. In addition to allowing the shared use of PL and other filters between lenses, the unified size is also highly convenient as it eliminates the hassle of finding the right lens cap when switching lenses. With these two lenses covering a broad angle of view, users can easily enjoy photography spanning various genres from portrait work to tabletop photography and landscapes. Have it all!

High performance autofocus system means you'll own every shooting opportunity
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.

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
