It's safe to say that Xiaomi's 15 Ultra is the most over-built camera phone available. This is the closest a phone has come to becoming a photographic, with a 50MP Leica primary sensor, an ultra-wide, a 3X floating telephoto, and an incredible 200MP periscope zoom.
The cinematography toolbox, in addition to the technology, is what makes it unique. It is the first Android phone to be certified by ACES for professional-level colour accuracy, and it has 10-bit log recording on all lenses and enables 4K@120 from its 100mm telephoto. If that's not enough, Xiaomi offers a photographic package that includes an additional 2000mAh battery, filter attachments, and a real shutter grip.
