Vivo has released the X300 Ultra, a camera phone aimed at video producers. The phone will feature a trio of cameras, including a large detachable zoom lens, and can also be purchased with an even larger lens. The X300 also supports recording at 4K resolution and at 120 frames per second, and shoots in 10-bit Log and Dolby Vision for wide dynamic range in the video files and easier color grading in post production. Vivo has also mentioned its color science and ability to color balance footage from the phone with regular cinema cameras. However, the phone's price and availability are still unknown.
