Canon EOS R5 Mark II firmware update

• Improves a delay in the live view display when shooting with the EOS Multi Remote app.
• Fixes the receiver camera sometimes failing to capture during linked shooting with EOS Multi Remote when the sender camera is connected to an FTP server.
• Fixes the camera sometimes restarting during shooting when Dual Pixel RAW is on.
• Improves operational stability.

1. Download firmware 1.3.2 for the EOS R5 Mark II from Canon's page (button below) and unzip it. The folder also has Canon's own instructions (PDF).
2. Format a memory card in the camera (this erases the card), then copy only the firmware file (R5213200.FIR) to the top level of the card, not inside a folder.
3. Insert a fully charged battery and the card, and turn the camera on.
4. Open the camera's setup menu, choose Firmware, and follow the screen to start the update.
5. Don't turn the camera off, open the card or battery door, or press buttons until the camera says the update is complete.

Canon's note (with version 1.3.0): a firmware update deletes registered data stored in the camera. Save it first with [Save/load registered data on card] and load it back after the update.
