Dust on the Sensor?

Sample Photos: Changing the Aperture (Before Cleaning) | Sample Photos: Changing the Aperture (After First Cleaning) | Sample Photos: Changing the Aperture (After Second Cleaning)

Here, I show some sample photos of the dust issue in 2016 before the cleaning, after the first cleaning, and after the second cleaning. The dust spot appeared on photos that I took in Bad Rappenau, Germany, on August 31, 2016 for the first time.

Sample Photos: Changing the Aperture (After First Cleaning)

After the first cleaning, the old dust spots were gone, but two major and a lot of smaller ones appeared. Therefore, I sent the camera once again to Leica for having the sensor cleaned.

Photos: Sample overview photos demonstrating the issue for six aperture values (f/16, f/11, f/8, f/5.6, f/4, f/3.5) at a focal length of 28 mm (equiv.); at f/8 and wider open, the dust is hard to see but can be recognized in the original photos (click images to see the original photos)

 

Sample Photos: Changing the Aperture (After Second Cleaning)

After the second cleaning, still one dust spot can be seen in the viewfinder (a second one is at the upper edge at a focal length of 70 mm equiv.). This time, I gave up and did not send the camera for to Leica for another cleaning...
