Get Leica M Monochrom Typ 246 at B&H Photo.
The monochrome sensor in the Leica M Monochrom Typ 246 is capable of terrific sharpness. To realize that sharpness, the focus must be spot-on and the depth of field must adequate. These examples all meet those requirements and thus show the best possible performance one can expect.
Examples include sizes up to full resolution (24MP).
Because the lenses deliver the goods, one wishes for 2X or 3X the megapixels, if only to reduce the staircasing of fine details (especially angled and very fine details on curved details). A sensor with 72 megapixels would be just about right.
