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.

Photos: Sample overview photos demonstrating the issue for four aperture values: f/16, f/11, f/8, f/6.4 (at 70 mm equiv. focal length)
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.

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...
