The Maestro III processor contributes to fast processing, continuous shooting up to 4.5 fps, and the Triple Resolution Technology of the M11 Monochrom, as well as helps achieve a wider sensitivity range than in previous M cameras. This ISO 125-200000 range has a lower base ISO than past M Monochrom models, for improved detail, along with a higher top end for greater flexibility when working in low-light conditions. And, due to the monochrome design of the sensor, noise levels and quality at ISO 200000 remains usable with a broad dynamic range and fine detail rendering.
