The 17-28mm F2.8 Di III RXD is a fast ultra-wide angle zoom developed specifically for mirrorless system cameras with Sony E-Mount. It offers outstanding image quality and a consistently large aperture of F2.8. In addition, with a length of only 99 mm and a weight of just 420g, it is as compact and light as any other lens in its class. It is the ideal lens to discover natural and urban landscapes from a new perspective. The optical design includes LD (low dispersion) and XLD (eXtra low dispersion) lens elements, which have been positioned to suppress chromatic aberrations as much as possible. Combined with the most advanced camera features, the full focal length range achieves very high imaging performance that fully exploits the potential of high-resolution sensors.

Short close range for photos with particularly dynamic perspectives
With the 17-28mm F2.8 you can take pictures even from close range. At 17 mm, the short close distance of 19 cm enables fascinating close-up shots at a magnification of 1:5.2; at 28mm, the nearest focusing distance is 26cm (1: 6). In addition, with the aperture wide open, a very low depth of field with an attractive blur (bokeh) is achieved. This effect is more pronounced the closer you are to the motif when shooting.

High-performance autofocus that focuses quickly and accurately in any situation
The autofocus system has a sensor that detects the current focus setting of the lens, and an RXD (Rapid eXtra silent stepping drive) stepper motor. When focusing, they ensure particularly high speed and precision, which enables the user to keep even dynamic objects continuously in the focus range. The ideal conditions for successful snapshots. The AF works so quietly that there is virtually no operating interference in the video recording.
