Canon 5D Mark II Black Dot Problem

Earlier this month, first users reported seeing black dots when shooting at high ISO levels. Canon has now recognized the problem (illustrated in the picture above) and is investigating what’s going on and how to fix it. At first view, the sensor is not the prime suspect, as it is used in other cameras that don’t suffer from this black dot issue. We’ll keep you posted when Canon will issue a fix, if at all.
