Sensor Problem? M9 with Rollei Sonnar 40mm 2.8

We had/have an amazingly beautiful day in Pensacola today. It "was my duty" to again experience Pensacola Beach. Some dust spots showed up on the M9
sensor. I cleaned it off later on. I did not manipulate the color except for adding a small bit of contrast. The colors were very rich, so that using some added contrast reduced the darkness of the colors a little. It was a Velvia Day, so to speak, and without any filters.

Post-processing was used. The water was green-blue. This is what Pensacola Beach is known for. This is what we could see with our eyes.
The M9 was set to ISO 200, and the Rollei lens aperture was set to 16.

I'm seeing severe banding in the skies, and literally hundreds of 'dust' spots. The more you look, the more you see. That is how my M-E looked before Leica replaced the sensor.

I am afraid that your camera sensor is corroded.

It does not look like sensor corrosion to me, although it may be that. It looks like it has been a long long time since the previous sensor cleaning, though. While that many particles may end up on the sensor in a short time, it is more likely the result is cumulative.

Unfortunatelly I have in my hands so far 4 cameras with sensor corrosion and that is the way it looks like:/
Personally I think that every single M9/M9P/ME/Monochrom will develop it sooner or later.

Missing the halos, but could be a very early stage.

As far as I know, Leica has a lifetime warranty for the M9 sensor.

If you would have Raids photos in full resolution and magnify them I am pretty sure that you will see the same as in dpreview article.

Yes, but this is not apparent in the photos that are posted here. It simply looks like dust spots. Raid even writes: "I cleaned it off later on."

Com'on, its just dust. It shows up because of the small aperture. Raid you must be a wide open shooter normally.
But use Visible Dust and it becomes invisible again. The images are nice, and need a clean camera.

I never seen so much dust on sensor before. But even new M-E, I have to clean it....
PP was kind of Q&D as well. Was it GIMP? It left strikes of visible gradation on top of the images.

This is bad news! So I need to send in my M9 to Leica you are saying.

I have not cleaned the sensor in quite some time. Maybe 6 months.

Yes, I had to use f 16 for these images, with white sand beach and strong sunlight.

So, what are your suggestions to me what to do, or what is the verdict here?
Carefully clean very well the sensor and test it again?

Share high res f16 photos of the sky or white wall with Leica.
To me it is obvious.

Thanks for the tip.
When I get home tonight, I will try to remember to post here an image without any post processing except changed from DNG to jpg for posting it here. I will also take a photo of a white screen at F 16.

I did not notice "white halos", though.
"Corrosion manifests in the form of white halos around darker specks, rather than the dark spots created by dust on a sensor. If you own a Leica M9, M9-P, M Monochrom and M-E, you can check for white spots in the same way as you might check for dust. Stop down the lens, and take a picture of the sky, or a sheet of white paper. At 100% examination, dust spots will manifest themselves as dark spots on your image, whereas the so-called 'corrosion' will appear as white spots or white rings around dark spots (see images above)."

looks like 'classic' corrosion to me, maybe have a professional sensor clean locally first, if the problem persist, send it to leica they will put a new sensor in for free.

It is not dust. It is exactly how my sensor looked when it corroded.

We have nobody here in Pensacola that is "a professional sensor cleaner".

Hi Raid

I envy your Pensacola ... Looks like a beautiful day.
The suggestion to send a sample image to Leica is a good one.
Whether it's dust or corrosion or both, eventually you will need to replace the sensor (free is a nice price).
May as well get the ball rolling. They put you in Queue which can be quite long.

Cheers!

Hi Andy,

Would I next contact the New Jersey based Leica service? They already replaced once the sensor in the M9.

Yes, Pensacola looks beautiful.

Do you have the Rocket Blower? If so, try it first and take picture of bright light source with white paper on the lens and at f16 and ISO200 after using of the Rocket Blower.
Also check how the sky did looks like in DNG, no processing, with gradation or not.

I used a rocket blower after I saw the dust spots. I will do it again more carefully this time.
Thank you for the detailed tip onw hat to check out.

Mine as well.

You are in the Leica queue, and shall now be months without your M9.

The good news is that when it returns you will know why you like it so much.

I once had a corroded sensor on my M3. Then I wound the lever and got an entirely new sensor. 36 new sensors on each roll, all for just $2.99!

Good luck Raid. It's gonna be a long wait. But this time you will get it back with the new type sensor, not a new sensor of the old corroding type.

I will contact as soon as possible the Leica service people in NJ.
I have many other cameras to play with until I will get back my M9.

I tried some sensor cleaning today. First, I used the rocket blower. Then I tried wet cleaning. Things looked worse afterwards! Then I went back to "dry cleaning" and used also the rocker blower. It needs more work, but I just wanted to share with you the results so that you can affirm either way; sensor damage or not. I used F 16.

Thanks for the update!

Number two looks promising as perfect candidate for at least two FF sized and unused wet cleaning swabs and dedicated for sensors cleaning liquid.

It took me three attempts to wet clean my M9 sensor completely. Lots of oily residue from the shutter, I think.

Before sending it in, clean the sensor .

As for banding, edited JPEGS will do it.

Look at some similar raw files.

Raid, glad this worked out without the apocalyptic step of sending your camera to Leica
But seriously, for some time now I have experienced similar black spots that show up on my M8 shots, particularly when I have wide angle shots at small apertures. It's enough to make me leave the camera home sometimes. I have used the dry blower but am a bit frightened about trying to clean the sensor myself beyond that. Can someone educate me as to how difficult and risky this is? The closest I have ever gotten to this is cleaning a lens with drop of lens cleaner on a microfiber cloth....

How difficult and risky depends on how capable you are. Some are ending with sensor scratching.

Is this one looks difficult?
