At MWC 2025, Xiaomi is showing off its new concept idea for the Xiaomi Optical Modular System – a micro four-thirds camera and lens combo that magnetically attaches to the rear of a prototype Xiaomi 15.
The system contains a 100MP Micro Four Thirds sensor, which Xiaomi is dubbing the Light Fusion X sensor, and is the same size as used in top mirrorless cameras from Olympus (OM System) and Panasonic.
