Here are compared the Leica M Monochrom Typ 246 to the Leica M240. Both are 24 megapixels utilizing the same sensor technology (an ideal comparison!). The MM246 omits the Bayer matrix color filter array (CFA) found on the M Typ 240 sensor.
A monochrome sensor ought to have inherently higher detail resolution and also a freedom from aliasing. The color sensor should deliver reduced resolving power along with color aliasing speckles and spurious resolution, due to the demosaicing process required for its Bayer-matrix CFA sensor.

This scene was chosen for its invariant lighting and preponderance of very fine detail that is right at the limits of sensor resolution. The Leica 24mm f/3.8 Elmar-M ASPH was used at f/8; it is about as sharp and flat field as a lens gets. No filters were used; this is clear mid-day harsh lighting.
