| The Vivo X300 Ultra will be available with two teleconverter accessories. |
Barcelona, Spain – If there is one thing Vivo knows how to do, it is smartphone photography. After dominating the camera benchmark charts for the last two years with the X Series, the brand is back at MWC 2026 in Barcelona to pull back the curtain on its next masterpiece: the Vivo X300 Ultra.
While we are still waiting for an official release date, the company is giving attendees a full sensory preview of what might be the most versatile camera system ever slapped onto a mobile device. However, the biggest news coming out of the Vivo booth isn't just about the phone itself—it’s about the insane accessories that strap onto it.
The Teleconverter Twist: One Lens Becomes Two
If you have been following the rumor mill, you likely heard whispers that Vivo was preparing a massive dual-lens teleconverter for the X300 Ultra. It turns out those whispers were only half-right.
In a recent hands-on video published by veteran tech journalist Ben Sin, a significant clarification has emerged. Vivo isn't releasing one dual-lens converter; they are releasing two separate professional-grade teleconverters.
At the booth, Vivo is demonstrating two distinct external lens attachments:
- The 2.35x Teleconverter: A physically smaller unit designed for everyday reach, ideal for portraits and medium-range shots.
- The 4.7x Teleconverter: A significantly larger piece of glass that pushes the optical limits, effectively turning the X300 Ultra into a pseudo-camera setup capable of reaching a staggering 400mm focal length.
This corrects earlier reports that suggested a single dual-lens solution. Instead, Vivo is offering modularity, allowing photographers to choose their adventure based on how much gear they want to carry.
Cross-Compatibility is Key
One of the smartest moves Vivo is making with this ecosystem is ensuring it doesn't alienate existing fans. The new, smaller 2.35x teleconverter isn't exclusive to the X300 Ultra.
According to the demo units on the floor, this new accessory remains fully compatible with last year's Vivo X200 Ultra and the recently released Vivo X300 Pro. This is a rare and welcome move in an industry that usually forces users to buy new hardware to access new features.
However, there is currently a question mark hovering over the massive 4.7x unit. It is unclear at this stage whether the older X200 Ultra or the X300 Pro has the lens alignment and processing power to handle that massive 4.7x zoom attachment. For now, it looks like that specific piece of glass might remain a crown jewel for the X300 Ultra only.
The "Camera Cage" That Unites Them
Vivo is taking the "professional camera" vibe seriously. At MWC, they are also showcasing a new camera cage—a protective rig that wraps around the device to provide a more stable grip and a standardized mount for the aforementioned lenses.
In a clever display of engineering, Vivo demonstrated the X300 Pro inside the X300 Ultra's camera cage, proving that the physical mounting system is designed to be interchangeable across the premium lineup. If you are a videographer upgrading from the Pro to the Ultra, your grip and mounts should still work.
Video Specs That Rival Dedicated Cameras
Putting the accessories aside, the X300 Ultra itself is no slouch. Vivo has confirmed that the device is built for filmmakers.
The handset is capable of capturing 4K video at 120 frames per second in Dolby Vision. For colorists and serious editors, it also supports 10-bit D-Log recording, providing a flat color profile that retains maximum dynamic range for grading in post-production.
To ensure those high-frame-rate videos are smooth, Vivo has equipped all rear cameras with Optical Image Stabilization (OIS) . This matches the hardware commitment found in rivals like the Samsung Galaxy S26 Ultra, ensuring that no matter which lens you are using—from ultrawide to periscope—your footage remains steady.
Charging: Leaving Samsung in the Dust
While the Galaxy S26 Ultra (currently available for pre-order at $1,299 on Amazon) remains a photography powerhouse, there is one area where Vivo is pulling ahead: charging speeds.
The Vivo X300 Ultra has been certified by TÜV Rheinland for global 100W wired charging. This certification is crucial as it confirms the device will support these ultra-fast speeds in global markets, not just in China. For context, Samsung’s charging tech has lagged behind its Chinese counterparts for years, and this 100W capability gives Vivo a massive advantage in daily usability.
The Waiting Game
Despite the flood of information and hands-on videos hitting social media, one crucial detail remains frustratingly vague: the release date.
Vivo is showing off a fully functional, polished device here in Barcelona, which suggests a launch is imminent. Sources on the ground, including leaks from Zions Anvin and posts on Weibo, suggest the phone is ready to go, but Vivo is likely waiting for the perfect window to drop the official pricing and availability.
For now, the X300 Ultra stands as the most exciting camera phone of the show. It doesn't just add a new sensor; it introduces a new way to play, with lenses and cages that blur the line between a smartphone and a professional camera rig even further.
