Just six months after its last flagship launch, Xiaomi has announced another one. The Xiaomi 12S Ultra packs a massive one-inch, 50.3-megapixel Sony IMX989 main sensor. And unlike the Sony Xperia Pro-I, the Xiaomi 12S Ultra apparently uses the entirety of its one-inch sensor. And the camera unit itself? Well, it looks gigantic.XiaomiInside, there’s a Leica Summicron 1:1.9-4.1 / 13-120 ASPH camera system that combines three rear cameras: a 50.3-megapixel main camera (23mm, f/1.9), along with the 48-megapixel ultra-wide camera (13mm, f/2.2) and the 48-megapixel periscopic camera (120mm, f/4.1).
