Camera: The Ideal Photographer's Dream

Built for photography, the Xiaomi 15 Ultra boasts a remarkable camera system co-engineered with Leica. It stands out for this:

• The 50MP Sony LYT-900 main sensor takes front stage and offers amazing dynamic range and detail. Whether photographing close-ups or landscapes, the clarity is quite exceptional.
• The Xiaomi 15 Ultra boasts 2 telephoto lenses, a 50MP sensor with 3x optical zoom and a 50MP sensor with 5x optical zoom, therefore enabling up to 28x lossless zoom and 120x digital zoom. One unique aspect is the optical zoom, which keeps great quality.
• Sharp, vivid images guaranteed by the 50MP ultra-wide lens Improved by telephoto sensors, portrait mode produces remarkable bokeh effects even for non-human objects like sculptures.
• Unlike most rivals, the 15 Ultra enables 8K video at 30fps across multiple lenses, enabling smooth switching between cameras during filming.
• Two Leica presets—authentic and vibrant—are included on the phone. Vibrant accentuates colors and saturation; the authentic option presents a natural look. Both perform rather well, but Vibrant mode usually manages low-light situations more well.
• Low-Light Performance: Particularly when running the Leica Vibrant mode, the LYT-900 sensor shines in low-light shooting. At very high zoom levels, though, noise becomes obvious in quite dark surroundings.
