EOS 5D Mark IV: Digital Lens Optimizer data

If you purchase a newly released Canon lens, you may find the lens correction data is not installed in your camera. This will be shown in the menu as “Correction data not available”. If this is the case and you would like to use Digital Lens Optimizer DATA (DLO), then data for new lenses can be added to the camera using the EOS Utility software supplied on the CD in the box. You may also find an error message saying “invalid correction data for Digital Lens Optimizer”. Again, use EOS Utility to add the correction data to your camera.
