Tamron makes large aperture ultra wide-angle photography more exciting, and for this lens we focused on usability. The 17-28mm zoom range was carefully selected; that paved the way for a surprisingly small size—just 99mm (3.9 in) long, weighing but 420g (14.8 oz). The overall length of the lens does not change during zooming, thereby offering consistent handling and stable shooting operations. (ref. animation for zooming) In addition, the Φ67mm filter size is small for a large aperture ultra wide-angle zoom lens. Plus, it shares the same filter diameter as the high-speed standard zoom lens in the series, the 28-75mm F/2.8 Di III RXD (Model A036). This means the same filters such as PL (Polarizer), lens caps and other accessories may be used for both models.
The 17-28mm zoom provides magnificent image quality without compromise despite its compactness. Two LD lens elements and one XLD element (which has properties close to fluorite) are precisely located to quash chromatic and other aberrations. In addition, the BBAR (Broad-Band Anti-Reflection) Coating applied to lens surfaces reduces ghosting and flare that are otherwise likely to occur when shooting against the sunset’s glow and other backlit situations. Leveraging camera functions*, it provides excellent optical performance matching the latest high resolution image sensors from edge-to-edge throughout the entire zoom range. The 17-28mm zoom invites you into the breathtaking world of ultra wide-angle photography.
* When shooting with the camera’s lens correction function enabled.
The 17-28mm zoom features an MOD of 0.19m (7.5 in) at the wide 17mm end, rendering a maximum magnification ratio of 1:5.2. At the tele end, the MOD is 0.26m (10.2 in) and the maximum magnification ratio is 1:6. In short, you can easily get close enough for a powerful shot. Your images can emphasize the perspective unique to ultra wide-angle lenses, and you can produce soft expressions with a shallow depth of field distinctive to large aperture lenses by opening the aperture and getting close to the subject. Versatile, functional and sensational—all at the same time.
The AF drive on the 17-28mm zoom 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 accurately detects the position of the lens enables high-speed and precise AF, which is ideal when shooting continually moving subjects or recording video. Perfect for street shooting and grab shots of groups of friends. And with a focusing system that is both smooth and quiet, the new 17-28mm zoom lets you shoot a video without worrying about picking up ambient drive sounds.
Tamron’s new 17-28mm zoom is compatible with many of the advanced features that are specific to mirrorless cameras. This includes:
- Fast Hybrid AF
- Eye AF
- Direct Manual Focus (DMF)
- In-camera lens correction (shading, chromatic aberration, distortion)
- Camera-based lens unit firmware updates
* Features vary by camera. Please consult your camera’s instruction manual for details.

Tamron has completed its assortment of three F/2.8 large aperture zoom lenses for Sony E-mount full-frame mirrorless. The models are the 17-28mm F/2.8 Di III RXD (Model A046) ultra-wide zoom, the 28-75mm F/2.8 Di III RXD (Model A036) standard zoom and the 70-180mm F/2.8 Di III VXD (Model A056) telephoto zoom. The greatest feature of the series is the excellent portability. Combined, the three lenses are unbelievably light at just 1,780g (62.8 oz), fulfilling the photographer’s dream of being able to easily carry three fast, potent zoom lenses at the same time.
Great things come in compact packages! This lineup includes other lenses that share the same filter diameter of 67mm. Lenses in this series feature small and light designs suitable for pairing with mirrorless cameras, and the filter diameter of each lens is the same 67mm. In addition to providing excellent portability when carrying multiple lenses, costly Polarizers, ND and other filters can be used interchangeably. Plus, the hassle of looking for different-sized lens caps when switching lenses has been eliminated. In addition to outstanding optical quality, you will enjoy the highest level of convenience across the entire lineup.
