Short close range for photos with particularly dynamic perspectives

With the 17-28mm F/2.8 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.
