It has been a one off issue, Unless the OP learns how to clean his own sensor it is going to be a difficult journey in the digital camera world. Only photographers who went through the experience of a new M9 can appreciate how good the situation is today 😁. Do you remember he M9 shutter was like an atomiser spraying oil all over the sensor, and it lasted ages. I think I've had oil on every sensor since (four cameras) but only a few spots. My default routine is the first clean is always a wet clean, after that it seems to be only regular dust. 1 Link to post Share on other sites More sharing options...

JonesKun Posted September 27, 2020 Author Share #23 Posted September 27, 2020 So the professional sensor and body cleaning did not help. The stains are unchanged and just like the other thread with the same issue the spots are still there. With dark photos it sometimes is enough to push them 1 or 2 stops and the stains become visible. I reached out to a forum member and it seems his issue was resolved when they found out it is oil/spots trapped between the cover glass and the sensor itself. So that may be why the usual sensor cleaning did nothing. Link to post Share on other sites More sharing options...

It is ISO 800. Another jpeg at ISO 3200 with +3 stops to demonstrate the positions of the spots clearly. https://we.tl/t-qFflpuKP2Y Link to post Share on other sites More sharing options...

To verify, take a regular shot of a white surface with aperture closed down. Any dust spots should be clearly visible or you can use LrC's "Visualize Spots".

The spots do not change their shape and size when shooting with aperture wide open or closed down. They stay exactly the same. The sensor is clean and there is neither dust nor oil on it. My last hope is that it might be oil between the protective glass and sensor itself, as someone else affected by this suggested ... so back to Wetzlar it is.

If you are 'stress testing' your sensor dust or oil will eventually show up at any aperture, it just depends how far you stress the image in processing it. And to be honest I find the idea of spots of oil between the protective glass and the sensor pure baloney. For there to be a spot it has to have sprayed from somewhere, so you are saying that as the shutter passes the sensor it somehow manages to spray droplets of oil for a good distance down the very, very narrow gap, and they land as round droplets? Have you ever seen a raindrop on a window and the pattern it makes? Link to post Share on other sites More sharing options...

It is NOT normal for those spots to appear after pushing 3 stops in post. And since they don't change with closing or opening the aperture, they stay exactly the same, it must be something with the sensor, and not a droplet on top of it. Maybe something that happened in the factory. Edited October 4, 2020 by JonesKun Link to post Share on other sites More sharing options...
Maarten Posted October 4, 2020 Share #30 Posted October 4, 2020 You have just bought a new camera. Have you already taken a properly exposed picture? For example a flower or -very popular on this forum- your cat or dog? When you test everything you buy to the very limits first, there is little joy to expect. A pity of such a wonderful purchase. 1 Link to post Share on other sites More sharing options...
