Removing a CFexpress card immediately after using it for recording may cause burns or cause you to drop the card, resulting in damage to the card. • After repeatedly recording, deleting and editing clips (if the memory is fragmented), you may notice slower writing speeds to the card and recording may even stop. In such case, save your recordings and initialize the card with the camera. Be sure to initialize cards especially before shooting important scenes.
