We would like to inform you of the lens firmware updates which incorporate a new algorithm to improve AF performance even further. Although we announced on April 14th, 2016 that release of the firmware updates is planned around June to August, the development has been delayed and the actual release will start from October onward.

For customers waiting for the availability of the lens firmware updates, we apologize for the inconvenience. We appreciate your understanding and will continue the development with our utmost efforts.
