*Based on Canon testing standards.

  • This information does not guarantee card recording operations when shooting in 4K. First, shoot a few test movies in the same conditions you plan to record in to make sure the card will write properly.
  • If the card`s writing speed appears to have slowed, low-level format it with a computer, and then initialize it with the camera. Be careful when low-level formatting cards, as all the data stored on the card will be erased.
