The advanced Image Stabilization system also senses camera motion and automatically optimizes the Image Stabilization for either normal shooting or panning (where vertical stabilization is applied, but horizontal isn’t to allow for side-to-side panning). The Image Stabilization system also has a function that detects the use of a tripod and responds accordingly. Other features that add to image quality are the 6-blade, circular aperture for exquisite soft-toned images, and the high speed, optimized AF system. As a finishing touch for convenience and safety, the lens includes a built-in zoom locking mechanism that holds the lens to its shortest, un-extended length.
