Leica M Monochrom Typ 246

Black Dots on White Spots Digital Artifacts

The Leica M Monochrom Typ 246 exhibits image digital artifacts best described as “black dots on white spots”. They often occur where there is a small white area; a black dot appears in the center of the white area. The effect can also invert to white dots on black spots.

UPDATE 07 Feb 2016: Leica may have fixed this issue in a firmware update in late 2015 (unconfirmed).
UPDATE 31 Dec 2020: whether fixed or not in the Leica M Monochrom Typ 246 is unkown to me. But the same type of artifacts exist in the Leica M10 Monochrom.
