With EOS Utility (EOS software), you can check the lenses of which correction data is registered in the camera. You can also register the correction data for unregistered lenses. For details, refer to the EOS Utility Instruction Manual (p.522). For lenses incorporating the correction data, it is not necessary to register the correction data to the camera. 189
