8. Troubleshooting
8.1 Overheating
The Canon EOS R5 Mark II, like many high-performance cameras, can experience overheating during extended video recording, especially in high-resolution modes (e.g., 4K 24fps nonstop recording for 20-30 minutes). If an overheating warning appears:
- Stop recording and turn off the camera to allow it to cool down.
- Consider using an external fan grip for prolonged video sessions to dissipate heat more effectively.
- Reduce video resolution or frame rate if continuous recording is essential.
8.2 Corrupted Files
In rare instances, files may become corrupted, particularly if the camera is powered off unexpectedly during recording or if overheating occurs. To minimize this risk:
- Always ensure the camera has sufficient battery power before starting important recordings.
- Use high-quality, reputable memory cards.
- Avoid turning off the camera while it is actively writing data to the card.
8.3 Focus Issues
If you experience issues with autofocus accuracy:
- Ensure your lens is clean and free of dust or smudges.
- Check your autofocus mode settings to ensure they are appropriate for your subject and shooting conditions.
- Calibrate your lens if necessary (refer to advanced camera settings or Canon support).
