I'm told by a Leica tech that some M9 owners have cracked sensors and don't realize it from improperly mounted sensors.
The reason is that the cracks appear as lines in the image often don't show up in smaller size prints.
Check towards the corners of your sensors first, with a magnifier.
Or have a tech check for you.
As these sensors are no longer used in the newer M, getting a cracked M9 sensor replaced now UNDER WARRANTY while replacements are still available takes on new urgency!
