Why is a 1/1.28-inch sensor for an ultrawide camera significant?

The ultrawide uses Sony LYTIA-818 at a 1/1.28-inch sensor size — most flagship ultrawide cameras use sensors between 1/2.8" and 1/2". At 1/1.28", the X300 Ultra's ultrawide has nearly double the light-gathering area of typical competitors, delivering substantially reduced noise in low light and wider dynamic range — making it competitive with the main cameras found on many premium smartphones.

What does CIPA 6.0 versus 5.0 stabilization mean practically?

CIPA 6.0 stabilization is an upgrade over the CIPA 5.0 standard used in the previous generation — each CIPA level represents approximately one stop of vibration compensation. Moving from 5.0 to 6.0 means noticeably smoother handheld video while walking, and the ability to capture sharp stills at significantly slower shutter speeds in low-light conditions without a tripod.

What is the hidden fourth sensor and what does it add?

The fourth hidden sensor will enhance color capabilities — likely the rumored 5MP multispectral camera — multispectral cameras capture color data beyond the visible light spectrum. Practical applications include more accurate skin tone rendering in portraits, precise color correction under artificial lighting (fluorescent, LED), and more accurate color reproduction across challenging lighting conditions. vivo introduced a similar sensor in X200 Ultra.

How does X300 Ultra's full camera system compare to Xiaomi 17 Ultra and Oppo Find X9 Ultra?

X300 Ultra pairs its main camera with a 200MP periscope telephoto, 50MP Sony LYTIA-818 ultrawide, and a fourth spectral sensor — Xiaomi 17 Ultra offers its own strong triple-camera system. X300 Ultra's standout differentiator is the exceptional 1/1.28-inch ultrawide sensor, which is significantly larger than the ultrawide sensors on competing flagship photography phones.

When is the exact launch and will it reach Arab markets?

X300 Ultra is expected in China later this month with a possible global launch around the same time — vivo's presence at MWC 2026 signals serious global intent. X200 Ultra reached select European and Asian markets; X300 Ultra may reach Arab markets through vivo's regional distributors in Q2 2026, though official confirmation is still pending.

The ultrawide camera uses Sony's LYTIA-818 sensor at a large 1/1.28-inch sensor size, rated for CIPA 6.0 stabilization — an upgrade over last year's CIPA 5.0 standard. This improves both video stabilization performance and low-light capability.

The Hidden Fourth Sensor: Color Enhancement

An image shared by Boxiao shows a fourth sensor concealed behind an emoji. While no details were revealed, Boxiao confirmed it will enhance the phone's color capabilities — pointing to the previously rumored 5MP multispectral camera.
