My M8.2 is getting old and worn. I don't know what the actuations are but it's probably in the tens of thousands. I'm also starting to see more frequently dark lines and dark bars on images taken in low light, and they seem to be appearing in increasingly brighter conditions (although still what most would consider fairly low light). I know Leica still produces the M9 (aka the M-E) which has a similar CCD sensor as the older M8. Do they still have the resources (or parts) to replace the sensor in my M8.2 if it came down to it?
