The Xiaomi 13 Ultra's headline feature is the 50 MP camera powered by a 1-inch Sony IMX989. This sensor has made headlines before as the biggest and most powerful sensor on the market in phones such as the non-Ultra Xiaomi 13, the Vivo X90 Pro Plus, the Sharp Aquos R7, and the Leica-rebrand of that Sharp phone, the Leitz Phone 2.
