vivo presented its new flagship camera vivo X300 Ultra to the public for the first time at the Mobile World Congress 2026 in Barcelona. The focus was not only on the smartphone itself, but also on an extraordinary accessory: the teleconverter with 400 mm equivalent focal length developed in collaboration with ZEISS. At the same time, vivo confirmed concrete plans for an international market launch before the end of the year – a clear signal of its global premium claim.
- 400 mm equivalent teleconverter with up to 200 MP optical resolution
- Gimbal OIS and motion tracking autofocus for stable super telephoto shots
- Modular camera cage with fan, physical buttons and accessory interfaces
- International market launch of the X300 Ultra announced for 2026
vivo X300 Ultra: 400 mm smartphone telephoto as a technological statement
The vivo X300 Ultra was presented at the MWC 2026 as a consistent further development of the Ultra series. The centerpiece of the presentation was the vivo ZEISS Telephoto Extender Gen 2 Ultra – according to the manufacturer, the world’s first smartphone teleconverter with an equivalent focal length of 400 mm. In combination with the high-resolution camera sensor of the X300 Ultra, images with an optical resolution of up to 200 megapixels should be possible.
The system integration is remarkable: the teleconverter was not designed purely as a clip-on lens, but as a coordinated extension of the camera architecture. Even when digitally cropping to a calculated focal length of up to 1600 mm, the image quality should remain at a high level. This seems technically plausible thanks to the combination of a high-resolution sensor, low-loss cropping and modern computational photography.
For image stabilization, vivo relies on a gimbal OIS system that compensates for mechanical movements. It is supplemented by a motion tracking autofocus, which is essential, especially at high zoom. Minimal camera shake is crucial for image sharpness, especially in the telephoto range – this is where the system addresses one of the biggest challenges of mobile photography.
The cooperation with ZEISS underlines the premium claim. APO image standards are designed to minimize colour errors and ensure high optical precision. The vivo X300 Ultra is therefore clearly positioned in the high-end segment and is aimed at demanding photographers and videographers.
Professional camera cage turns the X300 Ultra into a mobile production solution
In addition to the teleconverter, vivo presented a specially developed camera cage for the X300 Ultra. The modular frame extends the smartphone with several cold shoe mounts and quick-release connections for microphones, lights or external monitors. A two-hand grip improves stability for hands-free shooting, while physical buttons for shutter release and zoom allow for more precise manual control.
An integrated, multi-stage fan regulates the temperature during longer video recordings or intensive use. Especially with 4K or 8K video and compute-intensive image processing, active cooling is a relevant factor to avoid performance throttling. An external lens frame is also available to ensure full compatibility with the Telephoto Extender.
With this accessory ecosystem, vivo is pursuing a systemic approach: the X300 Ultra is positioned not only as a smartphone, but also as a modular camera platform. In view of the increasing importance of content creation, social video and mobile filmmaking, this step seems strategically logical.
The company has not yet announced a specific price or exact market launch date. However, the announced international launch later this year indicates that vivo intends to significantly expand its presence in the global premium segment.
Conclusion: vivo X300 Ultra as a serious camera competitor
With its 400 mm teleconverter, gimbal OIS and modular camera cage, the vivo X300 Ultra makes a strong statement in the field of mobile photography. The integration of optics, stabilization and accessories appears technically well thought-out and plausible. With the planned international market launch in 2026, the device is also likely to attract more attention outside Asia. Prices have yet to be announced, but the features clearly point to a premium flagship.
