Sensor Cleaning and result

I searched this topic in all categories and found 10.000 results. I don't found something for my question yet.

Some days before I „would/ must" shoot with Leica APO-Summicron-SL 2/90 ASPH and f20.

Normally I don't use this aperture 😉 I use normally f2.0 - f5.6.

On the picture I saw some stains in the sky .

Later I made test shoots on tripod and Clear White White Balance System from DigitalPhotographyKits.

 I made some bracket exposures from f2 to f22 😉

I clean my sensor with my tool from PhaseOne (cleaning supplies)

I think the sensor is clean?

The picture - f22- You can see in screenshot.

Does anyone have an idea what you see there?

I use the settings for good representation of the spots

Thanks for help!

I am not familiar with the Phase one cleaning tool. Is it a wet cleaning system? Because this looks like a sensor in desperate need of a good wet clean with Eclipse and swabs..

Thanks for feedback.

It is a wet cleaning system with two different liquids A an B.  I use it on my PO system long time.

Make sure that your bottle is not too old. The fluid is hygroscopic and can dissolve the plasticizers from the bottle over time, leaving hard to remove residue on your sensor. In this case I would let a good sensor cleaning service handle the  job.

This is from hard-gleaned experience. An old bottle of Eclipsed left white streaks on my M8 sensor - it took me two hours under a surgical microscope and multiple passes with Smear Away and a dozen swabs to get them off.

@Jaap

Thanks for feedback. I’m on traveling and cannot use a service yet. Which cleaning system You recommended?

I can order in www.

Exactly same thing happened to me Jaap. I've never used Eclipse again.

Thank for feedback.

Did You use a curve like mine to check stains?

I use a few drops of 99% isopropyl alcohol for wet cleaning. 99% evaporates very quickly so you will never see a streak unless you over do it with the amount used. I heard about this on the once famous Youtube video about the Leica technician that explained and demonstrated his procedures for cleaning Leica rangefinder sensors ( That video has since been taken down since)

I am surprised that there is no expiry date on the bottles with the cleaning liquid or that it has to be used up x days after opening the bottle.

Same here: always Isopropyl alcohol.
I used to work with non-imaging optics (optical fibers, lasers EDFAs this kind of stuff) for a few years. Iso was the go to liquid for cleaning glass surfaces.

FIS sells iso and many other cleaning materials for a fair price. https://www.fiberinstrumentsales.com/fis-isopropyl-alcohol-28-oz-bottle.html

No didn't use a curve, I notice spots on the images when using smaller apertures. My safaris are often in dusty conditions, I always carry 2 bodies, one of the reasons is also to avoid changing lenses. As a matter of habit I check for dust spots every evening, in most instances the rocket blower is enough. For stubborn spots I normally wait until I return home & do a proper wet clean.

Thank Mike

Your measures are certainly correct based on your experience.

Nevertheless, I would be interested in what I see on my sensor, apart from the suspected dust spots 😉

what you are pointing at is still durst that can be seen here too.

Leica moved the top glass layer away from the sensor to reduce durst visibility, but if you shoot a closer F stop they return.
