As of my knowledge cutoff in September 2021, Xiaomi 12 Pro has not been released, so I cannot provide specific details about its camera setup. However, if Xiaomi were to release a smartphone with a triple primary camera setup, it typically refers to a camera system that consists of three separate camera lenses, each serving a specific purpose.
The primary camera is usually the main lens responsible for capturing everyday photos and videos. The secondary camera might be a telephoto lens, which offers optical zoom capabilities, allowing you to zoom in on distant subjects without sacrificing image quality. The third camera could be an ultra-wide-angle lens, enabling you to capture a wider field of view for landscape shots or group photos.
It’s important to note that the actual camera specifications and features of the Xiaomi 12 Pro can only be confirmed once Xiaomi officially announces the device. For the latest and most accurate information, I recommend referring to Xiaomi’s official website or trusted technology news sources.
