[Leica] Sensor corrosion?

[Herbert Kanner]

Nathan, the M (240) has an entirely different sensor. In the first place, it is CMOS. The M9 sensor is CCD. I don’t know all that much about the difference in practice, except that the CMOS has remarkably less noise at extravagantly high ISO.

There may still be quality control problems these days with Leica. My M arrived with two-year-old firmware, and when the firmware was brought up to date, a problem showed up which forced Leica to replace the circuit board. However, my Fuji X100S had to be sent back twice for a defective switch because the low-level types who first checked it out when it was sent in for warranty repair reported it flawless and returned it untouched.

This just says I had bad luck. Most people have not had any problems, judging by the reaction when I did some bellyaching on the LUG last year.
