Tamron AF 17-28mm f/2.8 Di III RXD Sony FE mount

The 17-28mm F/2.8 Di III RXD is for a fast ultra-wide-angle zoom lens
is a fast ultra-wide-angle zoom designed specifically for Sony E-mount mirrorless system cameras. It offers outstanding image quality and a consistently wide aperture of F/2.8, plus it's more compact and lightweight than any other lens in its class, measuring just 99mm in length and weighing just 420g. It is the ideal Lens to discover natural and urban landscapes from a new perspective. A lens for creatives, discover the world from a whole new angle!

The optical design incorporates LD (Low Dispersion) and XLD (eXtra Low Dispersion) lens elements placed to suppress chromatic aberrations to the greatest extent possible.

Combined with the most advanced camera features, very high imaging performance is achieved across the entire focal length range, fully exploiting the potential of high-resolution sensors.

High-performance autofocus that focuses quickly and precisely in any situation
The autofocus system features a sensor that determines the current focus setting of the Lens and an RXD (Rapid eXtra-silent stepping Drive) stepper motor. These ensure particularly high speed and precision during focusing, enabling the user to keep even dynamic objects continuously in focus.
The ideal prerequisites for successful snapshots. The AF operates so quietly that virtually no disturbing operating noise is recorded during video recording.

Short close-up distance for photos with particularly dynamic perspectives
The 17-28mm F/2.8 makes it possible to take photos even at close range. At 17mm, the short closest focusing distance of 19 cm enables fascinating close-up shots at a magnification of 1:5.2; at 28mm, the shortest focusing distance is 26 cm (1:6). In addition, a very shallow depth of field with an attractive blur (bokeh) is achieved with the aperture wide open. This effect becomes more pronounced the closer you are to the subject when shooting.

1.
Perfect complement to the popular Tamron 28-75mm F/2.8 Di III RXD
The new 17-28mm F/2.8 Di III RXD zoom lens is based on the same development concept as the 28-75mm F/2.8 Di II RXD (model A036) introduced in May 2018. The special features of both Lenses include their exceptionally high image quality and compact, handy design. With a length of just 99 mm and a weight of only 420 g, the Tamron 17-28mm F/2.8 is unrivaled in its class for compactness and lightness. The barrel does not change size when zooming or focusing, which contributes to the excellent handling of this ultra-wide-angle zoom Lens and makes this zoom an ideal choice for users who travel a lot. Together, the 17-28mm and 28-75mm weigh less than a kilo.

2.
Excellent imaging performance
The optical construction of the 17-28mm F/2.8 Di III RXD features 13 elements in 11 groups, including three aspherical lenses and two LD (low dispersion) elements, as well as an XLD (eXtra Low Dispersion) element that has characteristics similar to a fluorite lens. The combination of these lenses effectively suppresses chromatic aberrations and other optical aberrations. The lens surfaces are coated with Tamron's BBAR (Broad-Band Anti-Reflection) coating, which effectively suppresses reflections inside the Lens when shooting backlight. In combination with the camera functions*, very high imaging performance is achieved across the entire focal length range, fully exploiting the potential of high-resolution sensors.
* Lens Correction function must be activated.

3.
Short focusing distance for expressive perspectives
With the 17-28mm F/2.8, it is possible to take photographs even at close range. Because the closest focusing distance is shorter at wide angle than at telephoto, photographers can open up new creative possibilities for images with dynamic perspective and expressive depth (close objects appear larger, distant objects appear smaller). At 17 mm, the extremely short closest focusing distance of 19 cm (as with the 28-75mm F/2.8) enables fascinating close-up shots at an image scale of 1:5.2; at 28 mm, the shortest focusing distance is 26 cm (image scale 1:6).

4.
Quiet autofocus with RXD technology
The autofocus system features a sensor that detects the current focus setting of the Lens and an RXD stepping motor (Rapid eXtra-silent stepping Drive). These ensure particularly high speed and precision during focusing, enabling the user to keep even dynamic objects continuously in focus. At the same time, the autofocus works so quietly that virtually no disturbing focusing noise is recorded during video recording. The compact RXD technology also contributes significantly to the unmatched handiness of the 17-28mm F/2.8 Di III RXD.

5.
Weather sealed construction and fluorine coating
The bayonet ring and other critical areas of the 17-28mm F/2.8 Di III RXD are sealed against moisture and splash water. This makes it possible to shoot outside with the Lens even in adverse weather conditions. The front lens is coated with a water- and grease-repellent fluorine coating, which ensures that the lens surface is very easy to clean and less susceptible to contamination, such as fingerprints or dirt splashes.

6.
Sophisticated design and high-quality workmanship
Like the 28-75mm (model A036), the new 17-28mm (model A046) is designed with the zoom ring at the front and the focus ring at the rear. This makes the operation of both Lenses the same for the user. The design of the new Lens is based on the characteristic concept of Tamron's high-quality lenses, which are characterized by a special sense of detail, meticulous workmanship and optimal shaping. The salient brand features of Tamron's high-quality lenses include the bright gold ring and the intuitive operating concept.

7.
Versatile use in a duo with the 28-75mm F/2.8 Di III RXD (model A036)
Together, Tamron's 17-28mm and 28-75mm Lenses encompass a comprehensive zoom range from 17mm ultra-wide to mid-range 75mm telephoto focal lengths at consistently fast F/2.8 speeds. Weighing just 970g combined, the duo is the ideal complement for a compact mirrorless system camera. The models also share the same filter diameter (Ø 67 mm), so a set of polarizing or gray filters can be used on both, and the lens caps are also interchangeable.

8.
Compatible with Essential Camera Features
The Tamron 17-28mm F/2.8 Zoom Lens is compatible with many advanced features of mirrorless system cameras.

These include:
Fast Hybrid AF
Eye Detection AF
Direct Manual Focus (DMF)
Integrated lens correction (vignetting, color fringing, distortion)
Lens firmware update via camera
