IMPORTANT
• CFexpress cards can become hot due to the high operating temperature inside the camera. 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.
• About CFexpress and SDXC cards: You can use CFexpress and SDXC cards with this camera but these types of
cards are initialized by the camera using the exFAT file system.
- When using exFAT-formatted cards with other devices (digital recorders, card readers, etc.), make sure that
the external device is compatible with exFAT. For more information on compatibility, contact the computer,
operating system or card manufacturer.
- If you use exFAT-formatted cards with a computer OS that is not exFAT-compatible, you may be prompted
to format the card. In such case, cancel the operation to prevent data loss.
NOTES
• Proper operation cannot be guaranteed for all cards.
