My guess is either your sensor needs a wet cleaning, or your sensor is defective. If you clean your sensor and these marks/stains persist, try a second cleaning. If they are still present after that, return the camera to your Leica dealer and ask for a replacement. Since the camera is less than 30 days old since you purchased it, I would think your dealer could give you a replacement and send this one in to Leica Wetzlar to have it made right. Sensor cleaning is not brain surgery - there's no need to pay a camera store $50 or more to do it. See post #8 in this thread: Best of luck - let us know how things turn out. I have a M10P since august and when I did a long exposure picture I noticed some specs like the OP. Not so many, but anyway. It does not bother me, but I tried to blow the sensor with my rocket blower but I think it didn't had any progress. I had this with my M240 as well when it was new. I think it's some kind of oil.

lct Posted January 2, 2020 Share #23 Posted January 2, 2020 Advising a photog to clean the sensor of a new camera at the risk of voiding its warranty is something this lawyer would never do. The OP's camera has as defect. It is up to the seller to fix it, not to the OP unless he agrees to do it at his own risk obviously. 2 Quote Link to post Share on other sites More sharing options...

pippy Posted January 2, 2020 Share #26 Posted January 2, 2020 Not much new to add - I'm as mystified as anyone - but the thing which I found most odd was, if I have understood the issue correctly, is that the dots appear most prominently when the lens is wide-open; normally the ubiquitous dust spots are at their PITA best when the aperture is set to 'Wee'. If it were me I'd try out some more tests with the white A4 paper at various apertures and different ISOs to see just how regularly the phenomenon occurs. Absolutely bizarre. Philip. P.S. Not that it will be any help to the OP but it was curious to see that the group lowest-right were trying to replicate the 'Big Dipper'...

You broke the cover glass on a Leica camera cleaning the sensor? Quote Link to post Share on other sites More sharing options...

tobey bilek Posted January 2, 2020 Share #29 Posted January 2, 2020 I would think anything cleanable would also show at ISO 100. 1 Quote Link to post Share on other sites More sharing options...

Well...... the fact that it was a third party mod the warranty was void anyway. Best not to panic about doing a simple task like cleaning a sensor. If you can’t handle it pay a pro. 1 Quote Link to post Share on other sites More sharing options...

Fallancer Posted January 2, 2020 Author Share #32 Posted January 2, 2020 Thanks all and I have sent the camera in. Those stains are invisible if lights are good despite of low ISO or high ISO, nor big aperture or small. It only exists (I my tests) in low near dark environment and fast shutter speed (don’t give the sensor enough time to capture the lights).

Nitnaros Posted January 3, 2020 Share #34 Posted January 3, 2020 I bet you are seeing a sort of digital artifact (capture or processing) and not physical stains; the latter ones would show up under many other conditions/pics pushing hard high ISO shadows exposes all kind of strange things that can go in in digital capture (as jdlaing, post above) said 1 Quote Link to post Share on other sites More sharing options...

I don't see it is there. In case of pushing high ISO shadows exposes I would expect to see just noises, my thoughts. Welcome, dear visitor!

calvinzhao Posted January 8, 2020 Share #36 Posted January 8, 2020 I have the same problem as you described. my body is m10p, and I try m35/1.4a,m21/3.4a and m50/1.4a,the black spots are in the same position. so, it can be sure the black spots are on the cmos.

calvinzhao Posted January 8, 2020 Share #37 Posted January 8, 2020 the circumstances were: I shot on iso 1600 ,iso 3200 and iso 6400, F1.4, under exposure,when I import the pictures to Lightroom, I found these black spots on the darkness area when I increase the exposure. I found different lens also have the same black spots on the same position. it looks like oil or some liquid on cmos. but I am quite sure the surface of cmos is very clean. I think it is a widespread problem on M10P. What can I do? mail the m10p to Leica and fix? please help. many thanks. Welcome, dear visitor!

BJohn Posted January 8, 2020 Share #38 Posted January 8, 2020 (edited) Sry for being that late to the party. My camera Leica M10 had the same issue. I figured it out after some time, as it was only visible with higher iso values (IIRC 6400+) and only in some cases (highly over exposing in post processing). Nonetheless I sent my camera in, they said it is a sensor fault which can occur in very rare cases. I got my camera replaced as they wanted my camera for further investigations. But it took quite some time to convince the Leica Customer Care that this is not some cleaning issue But I highly believe as of now they should be informed about such an issue. Hopefully this helps. TL;DR: This is a sensor issue, I believe it is linked to some hardware calibration. Cleaning does not help. And in my case, it was only linked to dark areas, shot with high iso and heavy lifting the exposure in post-processing. Not related to lens or aperture.

mike3996 Posted January 8, 2020 Share #39 Posted January 8, 2020 If these spots don't magnify in size/sharpness when closing down the aperture; if these spots don't manifest when shooting during daylight at low ISOs; if these spots don't show up in the internal cleanup routine; if these spots don't vanish or change places after a wet clean, it must be a hardware fault. Perhaps Leica replaces the unit; perhaps they'll send you a firmware that fixes it. 1 Quote Link to post Share on other sites More sharing options...
calvinzhao Posted January 8, 2020 Share #40 Posted January 8, 2020 Thank you very much!! I think it is cmos fault. I will mail the m10p to Leica. Really appreciate for your reply. Quote Link to post Share on other sites More sharing options...
