I’ve tested Vivo X300 Pro Camera phone in November 2025 and I loved its overall performance and the huge detachable zoom lens. in Mobile World Congress 2026The company is back with the X300 Ultra, a camera phone aimed squarely at video producers who want to break into the world of filmmaking. I should take a closer look at the phone on MWC showroomBut Vivo is keeping a lot of information about this device secret, including price and availability. But there are a few pieces of gold that I have been able to extract.
The X300 Ultra will have a similar trio of cameras as the Pro model I tested last year and will support the same massive telephoto lens, except you can also get it with a larger lens that offers up to 800mm equivalent focal lengths which should make this a beast for sports or wildlife photography where you don’t want to get too close to the action.
This camera grip will make holding the phone more comfortable.
The general specifications of the camera are not clear, but Vivo has spoken about its video credentials. First: It supports 4K recording at 120 frames per second from all its cameras, not just the main camera. It also shoots in 10-bit Log and Dolby Vision, allowing for wide dynamic range in video files and much easier color grading in post-production. To help with color grading, you can load LUTs (color filters primarily used by video professionals) onto your phone to preview the look while shooting. This is a useful addition and something more common in professional video monitors.
In its press release, Vivo talked about its color science and its better ability to balance colors in phone shots with shots from regular cinema cameras, something I struggled with when I recently pitted the iPhone 17 Pro against a professional Cinema setup. The phone also features advanced stabilization and better microphones for high-quality audio, although if you’re bothered about cinematic quality, you’ll almost certainly be using external stabilization (like a gimbal or tripod) and certainly external microphones.
If you want to use it on a proper production set, you’ll probably want to rig it up on a tripod like this one.
To that end, Vivo also offered the phone with a range of accessories from Smallrig, including a cage for mounting accessories like grips, lights and microphones, all of which were present and correct in the models I saw. While Vivo has said these are part of the phone’s ecosystem, they’re all commonly available components from SmallRig (albeit with Vivo branding) so I’m not sure if there’s anything phone-specific here.
I’m looking forward to seeing more of this phone and definitely keen to get it in my hands to see what kind of video quality I can get from it. your YouTube creatorI’m always looking for ways to improve production quality without carrying heavy equipment, and the X300 Ultra might be the phone I need. That, or Wild robot phone Of honor.
