Xiaomi's looking to put a big smile on shutterbugs' faces with a new, monstrous smartphone camera. On Wednesday, the Chinese company announced the Xiaomi 12 Pro, the first product to use Sony's massive 1/1.28-inch IMX707 sensor.

For comparison, the Samsung Galaxy S21 Ultra has a 1/1.33-inch type sensor for its wide rear camera and a 1/2.55-inch sensor for its ultrawide rear camera.
