If your lens has never been updated, it is worth doing for video.
How to update
- Download the lens firmware from Canon's page (button below). The download has the firmware file (RF023108.afu) and Canon's own update instructions (PDF).
- Read Canon's PDF first and follow it: the update runs from a compatible EOS camera with the lens attached.
- Use a fully charged battery, and don't switch the camera off or remove the lens during the update.
- Afterwards, check the lens version in the camera menu.
