Tamron 17-28mm f2.8 Di III RXD Sony E-mount Customer Return

The 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 imaging 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 and focusing, contributing to the excellent hand-holding of this ultra-wide-angle zoom lens and making this Zoom the ideal choice for users who travel a lot. Together, the 17-28mm and 28-75mm weigh less than a kilo.

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 one XLD (eXtra Low Dispersion) element that has similar characteristics 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. Combined with the camera functions*, very high imaging performance is achieved across the entire focal length range, fully exploiting the potential of high-resolution sensors.

Short focusing distance for expressive perspectives

The 17-28mm F/2.8 makes it possible to shoot 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-ups at a reproduction scale of 1:5.2; at 28 mm, the shortest focusing distance is 26 cm (reproduction scale 1:6).

Quiet autofocus with RXD technology

The autofocus system features a sensor that determines 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 unrivaled handiness of the 17-28mm F/2.8 Di III RXD.

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 splashing water. This makes it possible to shoot outdoors 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.

Sophisticated design and high quality workmanship

Like the 28-75mm (model A036), the 17-28mm (model A046) is designed with the Zoom ring in the front and the focus ring in 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 the high-quality Tamron lenses, which are characterized by a special sense of detail, meticulous workmanship, and optimal shaping. The salient brand features of the high-quality Tamron lenses include the bright gold ring and the intuitive operating concept.

Compatible with essential camera functions

The Tamron 17-28mm F/2.8 Zoom lens is compatible with many advanced features of mirrorless system cameras. These include:

• fast hybrid autofocus
• eye-detection AF
• direct manual focus (DMF)
• built-in lens correction (vignetting, color fringing, distortion)
• update lens firmware via camera
