The X300 Ultra’s camera cage provides cross-compatibility with the X300 Pro as well, as demonstrated in one image below. Moreover, the X300 Ultra can be paired with existing 2.35x teleconverters, too. Unfortunately, it is unclear at this stage whether Vivo’s new 4.7x teleconverter will work with the X200 Ultra or X300 Pro.
Setting that aside, Vivo has confirmed that the X300 Ultra can capture 4K/120 FPS videos in Dolby Vision and 10-bit D-Log. Also, the company has optically stabilised (OIS) all rear cameras just like the X200 Ultra before it, and to match the Galaxy S26 Ultra (curr. $1,299 on Amazon). TÜV Rheinland has confirmed that the X300 Ultra supports 100 W wired charging globally too, giving Vivo’s next flagship an advantage over Samsung’s equivalent. A precise release date remains unknown at this stage, though.
