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

The new 11-20mm F2.8 zoom is the world's first ultra-wide-angle zoom lens for Sony E-Mount APS-C mirrorless cameras with an aperture of F2.8. Despite its high speed of F2.8, the Lenses is very small (86.2mm) and feels perfectly balanced on a compact APS-C mirrorless camera body. It is the ideal ultra-wide-angle Lens for regular use. In the 11mm ultra wide-angle range, the Lenses shows amazing close-up performance, achieving a MOD (Minimum Object Distance) of 0.15m and a maximum magnification of 1:4, a feature that invites wide-angle macro shots that take advantage of the creative effects of naturally occurring distortion that only ultra wide-angle lenses can offer.

The new zoom is protected by a moisture-resistant construction and fluorine coating for outdoor shooting.
With a focal length of 67mm, it is identical to TAMRON's fast standard zoom lens 17-70mm F/2.8 Di III-A VC RXD (model B070) for Sony E-Mount APS-C mirrorless cameras, as well as almost all Lenses in the TAMRON series for full-frame mirrorless cameras, which also fit APS-C cameras. The Lenses is compatible with many of the features that Sony builds into its cameras, including Fast Hybrid AF and Eye AF, and is packed with features that support convenient shooting. Thanks to its highly practical features, photographers can enjoy the outstanding image quality of this ultra-wide-angle lens with its fast F2.8 aperture.

1.
The world's first F2.8 ultra wide-angle zoom lens for mirrorless APS-C cameras
The 11-20mm F2.8 is a true ultra wide-angle zoom lens with an aperture of F2.8 over the entire zoom range. At the same time, it is compact, lightweight and very practical. You can enjoy the unique and powerful world of ultra wide-angle photography at the 11mm end (equivalent to 16.5mm on full frame). The 20mm focal length (the full-frame equivalent of 30mm) is ideal for regular use and works well for occasional Schnappschuss, such as street photography. The 11-20mm F2.8 is a compact, lightweight Lenses with a high aperture of F2.8, providing greater freedom in a wide range of shooting situations.

2.
Compact and lightweight for outstanding ease of use
The 11-20mm F2.8 is only 86.2mm long and weighs just 335g. For a fast F2.8 ultra-wide-angle zoom lens, it is remarkably compact and lightweight. Combined with an APS-C mirrorless camera body, it allows the photographer to have a responsive image capture system without being hindered by the size or weight of the Lenses. It provides a comfortable user experience when photographing and shooting video with a small tripod or gimbal stabilizer.

3.
Outstanding optical performance
The construction of the 11-20mm F2.8 comprises 12 elements in 10 groups. Two precisely arranged GM (Glass Molded Aspherical) lens elements ensure high resolution across the entire image, from edge to edge. In addition, the 11-20mm F2.8 has one XLD (eXtra Low Dispersion) and two LD (Low Dispersion) lens elements, which ensure sharp images in which optical aberrations are strongly corrected. It also features BBAR-G2 (Broad-Band Anti-Reflection Generation 2) coating, which reduces ghosting and stray light to a minimum and allows the smallest details of objects to be seen even in backlighting. The combination of these properties ensures sharp images with natural colors and rich saturation.

4.
MOD of 0.15m at the 11mm focal length
The 11-20mm F2.8 offers an MOD (Minimum Object Distance) of 0.15m at the 11mm focal length setting and 0.24m at the 20mm setting. This results in better and more versatile close-up performance than existing ultra wide-angle zoom lenses at their widest focal length. At its widest focal length setting of 11mm, it has an amazing maximum magnification factor of 1:4, enabling wide-angle macro shots that take advantage of the unique perspective of ultra-wide-angle Lenses while utilizing the expressive bokeh created by the fast, bright maximum aperture of this lens.

5.
A user-friendly, uniform 67mm filter size for the entire series
The 11-20mm F2.8 is so light that the combined weight of this lens and the standard 17-70mm F/2.8 Di III-A VC RXD zoom lens (model B070) for Sony E-Mount mirrorless EPS-C cameras is only about 860g. The combination of these two Lenses covers an extreme focal length range of 11mm to 70mm (equivalent to 16.5mm to 105mm on full-frame cameras) with a fast, wide aperture of F2.8 at each focal length, enabling a massive reduction in the size and weight of an entire mirrorless system without sacrificing capability. Like almost all TAMRON lens models for Sony E-Mount cameras, it has a standardized 67 mm filter size, which enables the mutual exchange of filters such as PL and ND filters as well as lens caps.

Further product features:
COMPACT AND LIGHT
The overall length of the lens is 86.2 mm in the retracted position (20 mm setting). With a weight of only 335 g, the camera/lenses combination weighs only about 840 g. This makes it easy to carry the Lenses all day long. Due to the optical design, the shortest overall length is 20 mm. The longest wide-angle setting is 11 mm.

EXCELLENT BALANCE WITH THE CAMERA BODY
The low weight of the Lenses and its good balance with the camera body make it a perfect addition and ideal for video recordings with a gimbal. The full-frame equivalent field of view of 16.5 mm to 30 mm also offers easy handling and versatility.

EXCELLENT OPTICAL PERFORMANCE
Although it is one stop brighter than F4, the 11-20mm achieves higher MTF performance.
The 11-20mm uses one XLD lens element and two LD lens elements as well as two GM lens elements, which are used to achieve extremely high resolution from the center and clear images with suppressed chromatic aberration. If you use the camera's internal aberration correction, you can take high-resolution photos with even higher contrast.

Weatherproof construction
The rubber seal prevents moisture from entering the Lenses, ensuring safety during outdoor use.

Steppingmotor (RXD)
Equipped with RXD (Rapid eXtrasilent stepping Drive). The stepping motor is an actuator that can accurately control the rotation angle of the motor without a reduction gear and can directly control the focus lens. The stepper motor is a gearbox that can directly control the focus lens, which is good for quiet shooting and provides excellent AF performance for videography.

Direct Manual Focus (DMF)
Compatible with Direct Manual Focus (DMF), which allows the user to manually adjust the focus after using autofocus. You can instantly switch from AF to MF for easy focus adjustment. It is also compatible with single AF (AF-S) and continuous AF (AF-C).

Fluorine coating
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 susceptible to the damaging effects of dirt, dust, moisture and fingerprints.

**Proprietary TAMRON Lens Utility™ software tool for customization of the Lenses and firmware updates

The 28-75mm F/2.8 G2 is compatible with the new TAMRON Lens Utility, which was developed by Tamron itself. The TAMRON Lens Utility can be operated via a computer by connecting the Lenses to the Connector Port via a USB-C cable. The user can customize the functions and update the firmware via the Lens. Personal customization offers flexible shooting options that can be adapted to the shooting situation, whether photo or video shooting.
