C | Changing the mount
1. Remove the rear lens cap.
2. Remove the four torx screws of the silver EF mount with a T6 torque wrench and
place the mount and the screws on one side.

securely fastened to the EF mount (or F, MFT or E Mount) at the factory.
3. Remove the eight torx screws of the black EF adapter ring and place the ring and
the screws on one side.
ȴ The silver support bracket is already installed on the EF adapter ring at the
