Featuring a new higher-resolution design, the M11's 60MP full-frame CMOS sensor also features a back-illuminated (BSI) design that offers improved noise performance and faster readout speeds. The higher resolution suits more detail-oriented applications, like landscape and architectural subjects, and the noise-reduction benefits of the BSI design improves clarity and color accuracy when working in low-light conditions with higher ISOs.The sensor's physical design also includes an updated ultra-thin dual-layer filter glass, which absorbs UV and IR wavelengths for greater clarity and more accurate rendering from the M lenses.
