Why can Xiaomi 12 only be enlarged by 10 times?

Zoom ability problem. Xiaomi 12 is a Xiaomi brand mobile phone, and its performance is directly "full". Xiaomi 12 can only be enlarged by 10 times because of its zoom ability. Xiaomi 12 can support digital zoom up to 10 times, but does not support optical zoom function. Without the telephoto lens, the zoom ability of Xiaomi 12 is not excellent.
