3. Autofocus System: The lens features an integrated Hyper Sonic Motor (HSM) for fast, quiet, and accurate autofocus performance. An optimized autofocus algorithm enhances focusing speed and precision, while the full-time manual focus override allows photographers to make manual adjustments effortlessly.
