It can be put into normal or active mode when taking pictures with intense movement. Unique to this lens is the Silent Wave Motor, which combines ultra-high-speed auto focusing with exceptional accuracy and silent operation. All the features of the lens deliver excellent quality output in combination with the f/4 aperture.
