The Vivo X300 Ultra is shaping up to be the most ambitious camera phone of 2026, and now we finally have our first real-world look at the device in action.
Just hours after Vivo product manager Han Boxiao teased the first official images on Weibo, popular tech reviewer Ben Sin has dropped an exclusive hands-on video that gives us our clearest view yet of the company's upcoming "professional V-single" flagship.
First Impressions: A Camera Kit Like No Other
In the video, Sin demonstrates what might be the X300 Ultra's most jaw-dropping feature: a detachable telephoto lens attachment that transforms the phone into a bona fide superzoom shooter.
The accessory, officially branded as the "Zeiss Telephoto Extender Gen 2 Ultra," clips onto the back of the device and optically extends the built-in telephoto lens from 85mm all the way to a staggering 400mm. When combined with the phone's in-sensor cropping, users can effectively reach 800mm while maintaining what Sin describes as "very usable image quality."
That's a focal range that simply doesn't exist on any other smartphone currently on the market.
What Vivo Is Officially Teasing
Han Boxiao's original Weibo post, shared during the opening hours of MWC, frames the X300 Ultra as the next evolution in Vivo's "V-single" concept – a device built from the ground up with professional photography and videography in mind.
According to the executive, the X300 Ultra isn't just about incremental hardware upgrades. It's about fundamentally rethinking how a phone can serve as a creative tool. Key innovations being demonstrated at MWC include:
- The 400mm Zeiss Telephoto Extender: Dubbed the "king of teleconverters," this accessory aims to set a new standard for smartphone zoom photography.
- A New Professional Grip: A redesigned photography grip with enhanced controls for a more tactile shooting experience.
- The SmallRig Professional Video Expansion Kit: Already tested during last year's CCTV Spring Festival Gala, this kit points to serious professional video ambitions.
- Pro-Grade Video Features: The phone boasts a new "Pro" video mode with a professional camera-style interface, full support for 4K 120fps recording in 10-bit LOG across all focal lengths, and the ability to load custom 3D LUTs for real-time monitoring.
The "Pocket Cinema Camera" Vision
Han's post makes it clear that Vivo's goal with the X300 Ultra is ambitious: "to create a professional V-single that is truly capable of heavy-duty work, easy to use, and convenient – a new species of imaging that combines the advantages of both cameras and phones."
The emphasis on uniform 10-bit color science and LOG recording across all three rear lenses (the "Zeiss大三元" or "Zeiss big three") suggests that Vivo is serious about winning over videographers who need consistent color grading flexibility, whether shooting on the main wide, ultra-wide, or telephoto camera.
What We Still Don't Know
While Ben Sin's video confirms the physical design and the teleconverter's zoom capabilities, Vivo has placed a tight lid on detailed specifications. The video is more of a tactile preview than a spec dump, likely because the official China launch isn't expected until later this month.
Key questions remain:
- What are the full specs of the main camera sensors?
- How does image quality hold up without the accessory kit?
- What chipset will power the device (the Snapdragon 8 Elite Gen 2 is a strong bet)?
- What will the phone actually cost?
A global launch is currently anticipated for April 2026. As MWC continues in Barcelona, we'll be keeping a close eye out for any additional leaks or official reveals that fill in the remaining blanks. One thing is already clear: the 2026 smartphone camera wars just found a new heavyweight contender.
