Xiaomi has unveiled its latest T Series smartphones, the Xiaomi 17T and 17T Pro, both co-engineered with Leica. Both new smartphones feature triple rear camera arrays, although the specific cameras available differ. The more affordable, smaller 6.56-inch Xiaomi 17T features a 50-megapixel main camera with a Type 1/1.55 sensor and 23mm equivalent f/1.7 lens. Meanwhile, the 17T Pro, which has a 6.83-inch display, sports a larger Type 1/1.31 50MP sensor, likewise with a 23mm f/1.7 equivalent prime lens.
