Camera phones just got serious again. Vivo walked into MWC 2026 in Barcelona with arguably the most ambitious smartphone camera system shown at the event: a 200MP periscope telephoto, a 400mm Zeiss teleconverter attachment, and 4K 120fps Dolby Vision video across all three rear cameras. The message was clear: the X300 Ultra isn’t here to compete with last year’s flagships. It’s here to make professional photographers question why they still carry a second bag.
The launch date is confirmed March 30 in China, with global availability following shortly after. And this time, Vivo isn’t keeping it locked to the Chinese market. The X300 Ultra will be the first X Ultra to go international, a significant move that puts it directly in the crosshairs of the Samsung Galaxy S26 Ultra and iPhone 16 Pro Max.
The hardware story starts with the cameras, because that’s where Vivo is swinging hardest. The primary shooter is a 200MP Sony LYT-901 on a 1/1.12-inch sensor, one of the largest mobile sensors available paired with a 200MP Samsung ISOCELL HPB periscope telephoto with Vivo’s own processing on top. Below the module sits a 5MP multispectral sensor, which captures light data beyond the visible spectrum for more accurate colour reproduction in complex lighting. Zeiss optics and tuning run throughout.
The headline accessory is what Vivo is calling the “Big Gun 400” a 400mm Zeiss teleconverter that physically attaches to the phone and delivers a claimed 17.4x optical zoom with full 200MP output. Push further with in-sensor cropping and you’re looking at an equivalent 1,600mm reach territory that belongs to wildlife photographers and sports shooters, not smartphones. For context, the Samsung Galaxy S26 Ultra maxes out at 200mm optical zoom. The Vivo X300 Ultra, with the accessory attached, doubles that in pure optical reach.
Video gets the same treatment. The X300 Ultra records 4K 120fps in both 10-bit Log and Dolby Vision across all rear cameras, not just the main lens. Full-range 3-degree OIS video stabilisation keeps footage clean even while moving. Vivo is explicitly positioning this as an end-to-end production device, pairing it with a grip handle, cooling fan attachment, and external light supporting a full creator kit straight out of the box.
The X300s is the quieter sibling but no less impressive on paper. It carries a 6.78-inch BOE Q10+ flat AMOLED display with 144Hz refresh, ZEISS colour calibration, and Circular Polarization Light 2.0 for reduced eye strain. The camera system is a 200MP ZEISS setup, and dual symmetric speakers handle audio. The real talking point, though, is the battery, a 7,100mAh cell, the largest Vivo has ever fitted into an X-series phone, up from the already-generous 6,200mAh in the X200s. Under the hood sits a MediaTek Dimensity 9500, with up to 16GB RAM and 512GB storage. IP68 and IP69 dust and water resistance round out the package.
One thing worth flagging before launch day: Vivo and iQoo jointly announced on March 18 that retail prices on certain products are being adjusted upward, citing surging global semiconductor and memory costs. The X300 Ultra and X300s are almost certainly affected. Exact pricing hasn’t been confirmed yet but don’t expect last year’s numbers.
Design-wise, both phones debut in a new Film Green two-tone finish, a nod to the cinematic identity Vivo is leaning into hard this cycle. The X300 Ultra also comes in Black and Silver; the X300s in Blue, Purple, and Grey. The Vivo Pad 6 Pro tablet joins both phones on the March 30 stage.
Samsung’s S26 Ultra brings its own impressive camera credentials and a $1,299 price tag but its 200mm telephoto ceiling looks modest next to the X300 Ultra’s optical ambitions. Apple’s iPhone 16 Pro Max remains the benchmark for video colour science and ecosystem integration, but it doesn’t touch Vivo’s raw zoom capability or sensor size. For photographers who genuinely push mobile cameras to their limits, the X300 Ultra is the most interesting announcement of the year so far.
March 30 is the date. If you shoot, you should be watching.
