Hi guys. I tried sensor swab with solution and tried to clean my sensor, but unfortunately it didn't help either. Same black dot in the same place. I dont know if its possible, maybe sensor has some glass on it and dust is under this glass? I have no idea. I absolutely agree that new camera shouldn't have this kind of issue. And in my case i think it is something different than dust.I am sending back camera to store and we will see if they can clean it. You can notice this dust on my new video in variable aperture value. It is not HD but still visible. (sorry for accent)
