These are probably the best smartphone cameras coming from China in 2026 — the Vivo X300 Ultra and the Xiaomi 17 Ultra.
With a massive, round camera island on the back, both phones take the camera system seriously, but they also have a few fundamental differences.

Vivo is the only major smartphone maker that bets on a 35mm main lens. This is traditionally a lens best suited for taking pictures of people on the street. The Xiaomi uses a more common 23mm lens for its main camera, which is wider and better suited for landscapes. Here, Xiaomi has an advantage as it uses a slightly bigger sensor for the main camera.
But what if you want to achieve a similarly wide field of view (24mm-ish) on the Vivo? Well, you have to use a crop of the ultra-wide camera.
And here is where it gets interesting. Vivo understands that people still value a wide lens, so that’s why it features a massive ultra-wide camera with a sensor almost as big as its main camera. In fact, the 1/1.28″ ultrawide sensor on the Vivo has roughly 3.7 times more surface area than the 1/2.76″ ultra-wide sensor on the Xiaomi!
Finally, the third lens, a telephoto one uses the exact same sensor size on both phones, so this is the closest to hardware parity we get.
