The Tamron 11-20mm f/2.8 Di III-A RXD Lens for Fujifilm X features a constant aperture of F2.8. Even with its fast F2.8 aperture, the lens is very small and feels perfectly balanced on a compact APS-C mirrorless camera body. It's the ideal lens for everyday use with its full-frame equivalent zoom range of 16.5-30mm. And at the 11mm ultra wide-angle end, the lens provides stunning close-range shooting performance, with its MOD of 5.9”/ 0.15m and a maximum magnification ratio of 1:4. This feature invites creative wide-angle macro shooting that exploits the unique perspective that only ultra wide-angle lenses can provide. Additionally, the quiet RXD (Rapid eXtra-silent stepping Drive) stepping motor AF drive is perfect for both still and video use. This zoom lens is protected by Moisture-Resistant Construction and durable Fluorine Coating that provide extra protection when shooting outdoors. The compact size, fast F2.8 aperture, practical zoom range and superb image quality make the 11-20mm zoom an ideal choice for travel, landscape, street, and general photography.
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)3, 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.
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
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.
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.
