This is a 100 percent crop. I was using a 50 Summicron on bellows with a visoflex for some close-ups of a very small fruit. When I checked areas I noticed these odd spots, circles that appear to be on or under the cover glass. The sensor has been replaced once for separation of the cover glass from the sensor. The Summicron was set between f11 and f16, 4 second exposure with natural light (need to get a flash because for this type of work I prefer the freezing effect of flash). I use my special magnifier that is made for sensors and I can't see anything but then these are very small. Ideas?

This is the original of the fruit on a US penny:

Looks like it might have a bit of oil splatter on the sensor.. It's fairly common to some models.

I was thinking of that but these are tiny and the sensor has been cleaned and the spots are all basically the same size. I had a 30D Canon that was insane with oil, what a mess.

I cannot see the images, but from your descrIption it may be a known problem on one batch of sensors. Contact Leica.
 
I looked again with different light and it is "stuff" on the sensor that will not come off with cleaning. This is the second sensor, with the first one having the cover separating. Very frustrating to have this again and off on a distant island needing to use the camera as intended. I don't have a bellows for my Canon cameras and while I have macros, I can not get as close as I need even with extension tubes.

I have emailed Leica in NJ or wherever they are (David) and I hope they get back with me soon. Very frustrating with a 7,000 dollar camera body.

Now the images aren't coming up for me either but you can do and Open in new window and they do. I don't know why images from pbase sometimes do this.

Well Leica said there is no lubricant on the shutter and that this may be moisture. What is odd is that my 5DII, 7D and a couple of other Canons that get harder use in very bad conditions and except for the occasional dust, have nothing like this. And how could moisture get all over the sensor unless I opened the camera with the sensor exposed to vapor? The Leica is kept in a dry container with a dehumidifier when not in use and seldom gets the lens changed once work begins.

They said the sensor needs to be replaced (it has already been replaced due to cover separation) or taken out to be cleaned.
 
I rarely get dust. This is some sort of surface reaction.

6 in two months? I can see all the dust in the images, pretty bad.

They have replaced the M9 6 times?
 
No, not me. I have known some crooks and liars, a number of them reside here on this island.

The dust on your sensor will attract moisture in the air and give it a convenient place to form droplets. I suspect this is sticky dust or oil/gunk and just needs proper wet cleaning to remove.

Yeah, I have to and I bought a completly kit, even sensorvu cleaning, but In leica are very surprissed with my experiencie, a machine with only one shots has all these dust and more (like oil) but now, I'm waiting a new one and "a la carte" for me, I'm very Happy with that. Leica's people have treated me marvellously.

By the way, I'm very glad for not change my opinion of the m9 and stay with it, the new leica m9-p has the same , more expensive but with other look.
