Hello Natty Tang,
Thanks for reaching out to Microsoft Community. I understand how important the camera on your device.
I would like to inform you that both Surface Pro 8 and Surface Pro 9 have 10.0MP rear-facing autofocus camera with 1080p HD and 4k video. This means that if it's capable of 4K video then most likely you're looking at 30fps.
I hope this clarifies your concern. Otherwise, don't hesitate to respond to this thread if there’s anything else that needs to be addressed.
Regards,
StevenK
