He should watch those Chinese (I think) videos where they apparently have almost an assembly line for M9 sensor glass replacement. Frankly with the proper tools and training it didn't look like that hard of a repair procedure. Maybe 90 minutes total. I think Wetzler's repair facility definitely has talent at least as good as these young people in the video and could source the proper glass for pennies. But then they would be caught up with having to charge for something they used to give away. Ironically from what I understand all the M9 sensor replacements they did replace under warrenty will probably fail again as the problem with using the wrong glass was not addressed. That is probable cause for a law problem when you repair something with parts known too fail prematurely. I know that all the camera parts will fail sooner or later but this was a shitty response to the problem and a total lack of appreciation for a customer who invested a lot of money and trust in a brand's legacy of reliability. I realize they were in a corner with the only sensor manufacturer quitting the business but that can be addressed now with the procedure of replacing the glass.

And yet, strangely, there has not been a single known and confirmed incident such as you predict. For a few months they did indeed replace faulty sensors with the same type, but a new sensor was subsequently developed which fixed the issue. For info, not all replacements were done under warrenty (sic), but under a goodwill program set up for this issue. My camera had its sensor replaced foc long after its warranty had expired.

I fear your understanding does not fit the facts. After one year Leica -and the sensor manufacturer- had developed a new sensor cover glass. Since then there has been not one report of sensor corrosion. Quote Link to post Share on other sites More sharing options...

My bad you are correct that the second version of the replacement sensor has had no reported failures thus far. But the original sensor and 1st version replacement is a potential failure waiting to happen. Red Dot Cameras in London said the cutoff for cameras with a new sensor is a replacement after September 2015 for non Mono and after Feb 2016 for Mono. I would feel comfortable with an M9 with new sensor installed from those dates. Still a pity only recourse for owners with any future corrosion is Kolari replacing the filter for $1000 and pray the sensor doesn't get scratched.

PatrickT Posted November 20, 2022 Share #451 Posted November 20, 2022 Can an M9 with either a replaced non-corroding sensor from Leica, or replaced cover glass from Kolari, etc be considered completely fixed for the foreseeable future (at least in terms of the sensor)? I have the opportunity to buy an M9 with a Kolari - replaced cover glass (BG61). Camera is in great shape, has 9k shutter actuations and comes with all original boxes, accessories, etc for $2400. I want to make sure that if I buy this, I can use it for a long time. I realize that purchasing old technology is always a risk, but I'm most concerned about the sensor.

The Leica sensor is still fine 6 or so years after replacement. I don’t know about the others. 1 Quote Link to post Share on other sites More sharing options...

No idea, was quoted 3000 RMB last year for M9, but not sure about the larger one, most probably higher due to R&D, they expressed that they literally learned the replacement techniques through trial and errors, means destroying some sensors along the way. The latest news is that they can rewire the damaged and corroded tiny wires around the sensors (within reasonable degree of restoration, they did say if it's seriously damaged it's not possible to repair). http://b23.tv/k9KTJzd 1 Quote Link to post Share on other sites More sharing options...
leicam5cam Posted November 26, 2022 Share #454 Posted November 26, 2022 Hello I have been looking at different images to determine if what I see on the screen is dust or sensor corrosion on the Leica m9. The sensor itself looks very clean with the exception of a very faint horizontal line (light oil?) in the lower right of the sensor near the corner (same side as viewfinder, which is the left when taking an image but it is almost impossible to photograph and is just visible under light and at an angle). In any case, we did images of a blue sky at about f16 on a 90mm f2 summicron lens. The images start from fit, zoom to 100%, 200%, 300% and then 400%. I looked for the black dot and halo but am really unclear which this appears to be. I also am wondering, could this be debris in the lens? The summicron has a few specs of dust or debris in it. Is the test valid? What does this look like to you - dust or corrosion. This is not the only image that hast it, but I could do another test with a different lens but it is much harder to shoot the sky with a 50mm. Any comments would be appreciated.

dot-me-not Posted December 3, 2022 Share #456 Posted December 3, 2022 There is no question in my mind as to whether Leica should be offering repair services for M9 sensors. They should. It's handicraft work, after all, judging from the videos, with skill sets no more or less demanding than the repair of a malfunctioning M6. Repair services for old models has always been a part of Leica's heritage, has it not? These repairs are straight forward with the right tools.

I replaced 4 myself at home without any fancy equipment. One suffered from some dust particles left on the sensor surface but other three are perfect. It's clear to me Leica is trying to force users to upgrade and buy newer models. 1 Quote Link to post Share on other sites More sharing options...

Possibly, but I suspect the reason is due to Leica's warranty on repairs. The sensor is a component of the main circuit board. If Leica successfully replaces the cover glass it will inspect the rest of the body and provide a One Year warranty on the camera. That warranty would include the potentially 13-year-old circuit board against failure. There are no spares for the circuit board. I think this is why Leica does not offer replacing the cover glass as a service. Quote Link to post Share on other sites More sharing options...
dllewellyn Posted December 6, 2022 Share #460 Posted December 6, 2022 The sensor attaches to the main PCB with a flex cable. Two different parts. To replace the ICF/Coverglass well is not so simple though. I have repaired many but you need custom glass made, special equipment in order not to overheat the sensor, special cleaning mechanisms, etc. Quote Link to post Share on other sites More sharing options...
