Announced last yearX300 series modelsFollowing this, vivo officially unveiled its latest flagship imaging smartphone, the X300 Ultra, at MWC 2026. Notably, vivo chose to showcase the X300 Ultra at MWC 2026 first, but following past practice, it is expected to be officially launched in the Chinese market first, with specific launch information announced, before finally pushing this imaging monster to the international market later this year.
The X300 Ultra comes bundled with a 400mm super telephoto lens developed in deep collaboration with ZEISS, and also features a dedicated professional-grade camera cage with an integrated cooling system, demonstrating its strong ambition to become the king of mobile telephoto lenses.
Breaking the ceiling of mobile optics: Zeiss 400mm super telephoto teleconverter
The biggest technological highlight of the X300 Ultra is its debut of the "vivo Zeiss teleconverter Gen 2 Ultra". This is not only the only professional-grade optical component in the mobile device industry that supports a 400mm equivalent focal length, but it also achieves the stringent APO optical certification level, which can greatly eliminate chromatic aberration and purple fringing phenomena commonly seen in telephoto shooting.
Equipped with a high-resolution sensor boasting up to 2 million pixels, the X300 Ultra not only delivers pristine image quality at its 400mm optical focal length, but vivo also claims that even with digital cropping up to 1600mm, image detail remains highly usable. To ensure a high success rate at such extreme telephoto distances, vivo has equipped it with gimbal-level OIS optical image stabilization and motion tracking technology, significantly reducing image shake during long-distance shooting and telephoto video recording.
Turn your phone into a professional movie camera: Exclusive "professional-grade camera cage" accessory
This time, vivo is targeting professional video creators, simultaneously launching a "Professional-Grade Camera Cage" system tailored specifically for the X300 Ultra. This expansion frame features a modular and quick-release design, and boasts several features designed specifically for high-intensity shooting:
• Enrich and expand the interface:It has multiple built-in cold shoe mounts for quick connection of professional directional microphones and external fill lights.
• Physical control buttons:The dual-grip design not only improves the stability of handheld camera movement, but also integrates physical shutter buttons and physical zoom control buttons directly on the grip, providing intuitive operation comparable to a DSLR camera.
• Active cooling fan:The cage system has a built-in multi-stage active cooling fan to ensure that the phone will not throttle or interrupt recording due to overheating during long-term, high-specification (such as 4K or 8K) recording.
• External lens support:The extended frame perfectly supports the X300 Ultra's super telephoto lens, creating a complete ecosystem for mobile video creation.
