An STM stepping focus motor is also integrated into the lens' design to provide smooth, quiet, and fast focusing performance that is ideally-suited to video applications as well as tracking moving subjects. The rear focusing system, high-speed CPU, and an enhanced AF algorithm also contribute to quickened overall AF speeds. Full-time manual focus is also supported to permit fine-tuning of focus even while working in AF modes. Additionally, the front lens section does not rotate during focusing to better facilitate the use of polarizing filters.
