CCD sensors of the Leica M9 / M9-P / M Monochrom and M-E camera models // 2017 // Global // Leica News // World of Leica - Leica Camera AG After the middle of August the owner will pay for part of the Sensor replacement, the replacement includes a full CLA of the camera. Cameras bought new within 5 years continue with the free replacement. My M Monochrom is in for corrosion, my even older M9 shows no signs of a problem. I will check my M9 "again", so far it does not show any signs- and I know what to look for. Note that the S8612 cover glass is more efficient than the glass used to replace it, and it was used in the Kodak DCS/n and DCS/c sensors- far older than the M9.
