A Revolutionary Leica-Enhanced Camera System
Photography has always been a key pillar in Xiaomi’s flagship strategy, and the Xiaomi 15 Ultra 5G takes it to the next level. Developed in collaboration with Leica, the smartphone features a quad-camera setup, each sensor tuned for professional-grade imaging.
At the heart of this system is a 50-megapixel main camera equipped with a massive one-inch Sony LYT-900 sensor and optical image stabilization. This sensor is designed to capture more light, resulting in brighter and more detailed images, especially in low-light conditions.
Accompanying the main lens are a 3.2x telephoto camera ideal for portraits, a 5x periscope zoom lens for long-range shots, and an ultra-wide-angle camera offering a 122-degree field of view. Together, these sensors create an incredibly versatile camera system that excels in every situation, from landscapes to close-ups.
The front camera offers 32 megapixels of resolution and supports 4K video recording, ensuring crisp selfies and smooth video calls. Features like Summicron lens optimization, 14-bit RAW capture, 10-bit LOG video, and Leica-specific shooting modes make the camera system suitable for both casual users and professional content creators.
