vivo brought the X300 Ultra along to MWC, though calling it a “launch” would be generous. No full spec sheet, no pricing, no design reveal more of a controlled tease than anything else. They let people see the camera accessories, talked up the zoom numbers, and dropped the one piece of news that actually matters: the X300 Ultra is launching outside China.
That’s never happened with a vivo Ultra phone before. Every previous one stayed exclusive to the Chinese market, which meant anyone outside the country could only read about them and be annoyed. No confirmation yet on which specific countries will get it or what it’ll cost, but the commitment to an international release is new and worth paying attention to.
The teleconverter
The biggest talking point from vivo’s MWC showing was the vivo ZEISS Telephoto Extender Gen2 Ultra. Ridiculous name, but the specs are hard to argue with. It pushes the focal range to 400mm equivalent twice what last year’s X200 Ultra Photography kit offered and gives you up to 17x optical zoom when mounted on the phone.
Stack that with in-sensor zoom cropping and you’re looking at a total reach of 800mm. vivo is claiming full 200MP optical output from the setup and says image quality holds even at a 1600mm digital crop. That last claim will need real-world testing before anyone should take it at face value, but the raw numbers put it ahead of anything else in the phone accessory space right now.
Camera cage
Alongside the teleconverter, vivo showed off a Camera Cage that bolts onto the X300 Ultra and turns it into a portable video rig. Multiple mounting points for things like a flash, a cooling fan with different speed settings, and a tripod. Physical shutter buttons too, plus quick-release ports so you’re not fumbling with screw mounts between shots.
It’s aimed at people who shoot video seriously on mobile content creators, mobile filmmakers, that sort of crowd. Whether a full cage rig on a phone appeals to enough buyers to justify making it is debatable, but vivo is clearly positioning the X300 Ultra as a genuine production tool rather than just another phone with a good camera bolted on.
Rumoured specs
vivo kept the actual camera specifications quiet at MWC, but leaks have filled in most of the blanks already. The main camera is expected to use Sony’s LYT901 sensor at 200MP. The periscope telephoto reportedly gets a 200MP Samsung HPB sensor, which would make it one of very few phones running dual 200MP cameras across main and telephoto. The ultrawide is said to be a 50MP Sony LYT828, and a multispectral sensor is apparently part of the package too.
Dual 200MP on main and telephoto would be a significant move. Most competitors still use lower-resolution sensors on their telephoto modules and rely heavily on computational photography to compensate. If vivo actually delivers that hardware pairing with decent processing behind it, the X300 Ultra could genuinely shake up the camera phone rankings.
No launch date yet. No pricing. No confirmed market list beyond “outside China.” But vivo made its point at MWC the X300 Ultra exists, it’s going international, and the camera system is built to compete at the very top.
