At the heart of the camera is the same 47.3-megapixel full-frame CMOS sensor behind a fixed Summilux 28mm F1.7 ASPH lens—the same setup used in the standard Leica Q2. The system is powered by Leica’s Maestro II image processor, which helps to deliver 13 stops of dynamic range with an ISO range of 50 through 50,000.
