Pro Notes
- For uninterrupted 6K/5K/4K recording, ensure your camera is set to UHS-II and use V90 cards.
- On older bodies (UHS-I), the card will operate at the device’s lower supported speed class.
- Use the write-protect switch during offload to prevent accidental deletion; track serials for better media management.
