Leica M Typ 240 / M240 Can Have a Dead Pixel Column Too (same as With The M9)

Reader Andrew Wonder sends a Leica M Typ 240 image that shows a dead pixel column running the entire height of the sensor.

I first reported on this dead pixel column issue with my Leica M9P (CCD sensor) in Sensor Defect: Bad Pixel Column, thinking it might mainly be a CCD issue.

But it’s clear that the CMOS sensor in the M240 can exhibit the same issue. The dead column can be mapped out in firmware (by Leica), but I am not persuaded that this is sufficient: on certain types of straight lines, that missing column won’t look right, see example further below.

These three crops are from top, middle, bottom of the Leica M Typ 240 image.

Here is an example of what a bad pixel column can do to detail (Leica M9):
