The New Tokina AT-X 116 PRO DX-II is an update to the widely popular and award winning AT-X 116 PRO DX, 11-16 F/2.8 lens. There have been some adjustments made to the coating for slightly improved optical performance. Other than the optical coating change there are no changes to the Canon mount. The AT-X 116 PRO DX-II for Canon uses the same AF motor and AF drive system as the the previous model.

Tokinas 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 camera to focus manually. There is no need to change the AF-MF switch on Nikon cameras** and there is no second AF/MF switch on the lens for Canon, everything is accomplished by the focus ring.
