Precise Auto Focusing is actuated by combination of Tokina GMR sensor and SD-M (Silent Drive-Module).
Tokina's exclusive One-touch Focus Clutch Mechanism allows the photographer to switch between AF and MF simply by snapping the focus ring forward for AF and back toward the lens mount for manual focusing.
Additionally the mount area is sealed around making the lens more resistant to moisture and to stand up to the rigors of daily use in a wide variety of shooting conditions and environments.
