Vivo X300 Ultra Debuts at MWC 2026 with 17x Optical Zoom Accessory

The Mobile World Congress 2026 (MWC 2026) in Barcelona, Spain, served as the venue for the official preview of the Vivo X300 Ultra flagship device. This unveiling underscores Vivo's strategic intent to position the X series as a dedicated instrument for professional content creators and photography enthusiasts. The presentation centered on an advanced imaging system, supported by a new suite of optional accessories intended for serious mobile videography and photography applications.

The most significant hardware revelation is the optional 400mm Zeiss Telephoto Extender Gen 2, which extends the phone's reach to deliver a 17x optical zoom capability. This external lens effectively transforms the device, pushing the zoom range to approximately 800mm, or 30x, through in-sensor cropping while retaining substantial detail. This marks a considerable advancement from the previous generation, as the Vivo X200 Ultra offered a maximum optical reach of 8.5x with its 200mm external lens. The device itself is reported to incorporate a dual 200-megapixel camera array, featuring a 200MP Sony LYT-901 main sensor and a 200MP Samsung HPB periscope telephoto camera, both carrying Zeiss APO certification.

The imaging hardware is powered by the recently announced Snapdragon 8 Elite Gen 5 Mobile Platform, confirming the device's position at the forefront of the current hardware cycle. This chipset, which utilizes the third-generation Qualcomm Oryon CPU, is engineered for high performance, with peak speeds reaching up to 4.74GHz and offering up to 35% CPU power efficiency gains over the previous generation. The platform also integrates a next-generation Qualcomm Adreno GPU, providing a 23% increase in overall performance, which is essential for managing the computational load of advanced mobile imaging and professional video features like 10-bit Log and Dolby Vision across all rear cameras.

Vivo's commitment to the creator segment extends beyond optics, evidenced by the professional camera accessories unveiled concurrently. These include a secure grip handle, an active cooling fan to mitigate thermal throttling during sustained, high-bitrate recording, and a camera cage rig equipped with cold shoe mounts for external microphones or lights. This comprehensive toolkit suggests the X300 Ultra is engineered for extended, high-intensity operation, offering tangible utility for filmmakers. Furthermore, the device is confirmed to support professional-grade 4K 10-bit log video across all rear focal lengths, a capability often associated with dedicated cinema equipment.

Early assessments from reviewers, including Ben Gadget Reviews, have noted a significant enhancement in the device's stabilization system, even when operating at these extreme focal lengths. This robust stabilization is critical, as maintaining sharp frames at 400mm equivalent focal lengths requires sophisticated optical image stabilization, an area where Vivo has demonstrated proficiency with its micro-gimbal systems. The company has also confirmed that, in a departure from some prior Ultra models, the X300 Ultra will receive a wider global launch, moving beyond traditional China-exclusive releases. While the commercial launch is slated for the coming weeks following the MWC 2026 showcase, the overall ambition is clearly focused on bridging the functional gap between high-end smartphones and dedicated professional cameras.
