The world's first compact, lightweight F2.8 ultra-wide-angle zoom lens for Sony E-mount APS-C mirrorless cameras
Despite its fast F2.8 aperture, the lens is very small, at just 86.2mm and feels perfectly balanced attached to a compact APS-C mirrorless camera body, making it 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 an MOD (Minimum Object Distance) of 15cm 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 making them ideal for outdoor shooting. Its 67mm filter size is identical to Tamron's 17-70mm F/2.8 Di III-A VC RXD zoom lens for Sony E-mount APS-C mirrorless cameras and also most of the series of full-frame mirrorless cameras that also sit nicely on APS-C cameras too.
Compatible with many of the features that Sony builds into its cameras, including Fast Hybrid AF and Eye AF, the lens is packed with great features that help to support photographers in order to enjoy the superb image quality of this ultra-wide-angle, fast F2.8 aperture lens.
1 Among interchangeable F2.8 ultra wide-angle zoom lenses for Sony E-mount APS-C mirrorless cameras
(As of March, 2021: TAMRON)
1. The world's first F2.8 ultra-wide-angle zoom lens for APS-C mirrorless cameras
The 11-20mm F2.8 is an ultra-wide-angle zoom lens with an aperture of F2.8 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 F2.8 aperture, the 11-20mm F2.8 provides an exciting shooting experience with greater freedom in diverse shooting situations.
2. Compact and light weight for superior usability
The 11-20mm F2.8 is only 86.2mm in length and weighs just 335g. For a fast-aperture F2.8 ultra-wide-angle zoom lens, this is a remarkably compact and lightweight combination. 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 stabilizer.
3. Outstanding optical performance
The 11-20mm F2.8 construction includes 12 elements in 10 groups. Two precisely located GM (Glass Moulded Aspherical) lens elements assure high resolution across the entire image, from edge to edge. In addition, the 11-20mm F2.8 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. This combination of features works in harmony to provide sharp images with natural colours and rich saturation.
4. Close Focus at 11mm
The 11-20mm F2.8 boasts an MOD (Minimum Object Distance) of 15cm at the 11mm focal length setting and 24cm 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 exploits the perspective unique to ultra-wide-angle lenses, while also leveraging the expressive bokeh provided by the fast, bright maximum aperture of this lens.
5. A user-friendly unified 67mm filter size across the series
The 11-20mm F2.8 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. 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 your capabilities. Similar to most of the Tamron 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.
6. Quiet and Rapid RXD focussing - ideal for Video too).
RXD (Rapid eXtra-silent stepping Drive) 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
7. Moisture-Resistant Construction and Fluorine Coating
The addition of Tamron's Moisture resistant construction helps to protect your lens should you get caught with unpredictable weather. 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.
8. Compatible with many camera-specific features and functions
As with the range of lenses Tamron have created for Mirrorless Cameras in Sony E-mount, the 150-500mm F/5-6.7 lens is compatible with an array of special features and functions of the Sony Mirrorless system including Fast Hybrid AF and Eye AF
