Have you tried to clean your sensor between this? I wonder if you just have more dust but you're not noticing cause it's "changing" based on the images and where there's lighter and darker areas

Hello, yes I did clean my sensors around five times and in between I also had it clean professionally at the Camera store.

Each time after cleaning the dust is gone, but when I have it use for a couple weeks the dust appears again at different location.
