erl Posted December 20, 2014 Share #3 Posted December 20, 2014 It may. Affecting parameters have not been defined, or at least made public, AFAIK. humidity is suggested as one possible cause. Quote Link to post Share on other sites More sharing options...

jip Posted December 20, 2014 Share #5 Posted December 20, 2014 Who cares, get a free replacement anyway. Just shoot the damn thing instead of worrying. That's what kills Leicas. 12 Quote Link to post Share on other sites More sharing options...
tobey bilek Posted December 20, 2014 Share #6 Posted December 20, 2014 Same defective design in all. Cause is hi humidity and/or some sensor solvents . A repair person told me years ago that sensors were damaged by humidity caused condensation. So when you come in from the cold, allow the camera to cool slowly. I wrap the whole bag in a comforter for 6 hours. Similar precautions needed if you go from A/C indoors to warm humid outdoors. I would also open the shutter to clear the air behind it. Clean with blower, proper brush, and sticky wand. I am avoiding solvents. I will use a strong blast of canned air if desperate. Clear the nozzle first and keep the can upright. Use Dust Off or C134A A/C refrigerant with the Falcon trigger. I would not stick one of those plastic straw nozzles that might fly out and hit the sensor. So far so good for me, but I have low actuations in two years of ownership. Quote Link to post Share on other sites More sharing options...

wattsy Posted December 21, 2014 Share #8 Posted December 21, 2014 Who cares, get a free replacement anyway. I'd agree if the sensor replacement took a couple of weeks. As it stands my Monochrom sensor replacement is looking like taking a quarter of a year. 1 Quote Link to post Share on other sites More sharing options...
thighslapper Posted December 22, 2014 Share #9 Posted December 22, 2014 Same defective design in all. Cause is hi humidity and/or some sensor solvents . A repair person told me years ago that sensors were damaged by humidity caused condensation. ....errr ..... that's a bit of a throwaway statement with a lot of assumptions ...... .... we are talking here about a custom sensor made by a different company, a continent and 5 years apart .... whilst there may be similarities in the cover and adhesives used I would be surprised if Leica specified and had sufficient control over the manufacture that identical errors would ensue ........ time will tell Quote Link to post Share on other sites More sharing options...

erl Posted December 25, 2014 Share #16 Posted December 25, 2014 Stop worrying and use it. If it falls over, Leica have categorically stated they will fix it, no charge. You could be so lucky! Quote Link to post Share on other sites More sharing options...
Edward Louis Marit Posted December 25, 2014 Share #17 Posted December 25, 2014 How can you tell it is corroded? There was a long mark that could not be dislodged by cleaning and was visible when viewing the sensor with the shutter open. Doing the f16 wall test showed it on enlargement appearing as a row of bubbles. I had no idea what it was ( this issue had not yet blown up) and sent it to NJ who promptly replaced the sensor on their own volition. Hope this helps. 2 Quote Link to post Share on other sites More sharing options...

Jeff S Posted December 25, 2014 Share #19 Posted December 25, 2014 I believe the US warranty is 2 years on camera, 3 year Passport on lens. Jeff Quote Link to post Share on other sites More sharing options...
