I get a spot on all images with a light or sky blue background regardless of what lens I’m using

Hi Pete. It sounds like your camera needs a sensor cleaning! Check out these guides here: https://www.youtube.com/watch?v=UcRMizSnhttps://www.youtube.com/watch?v=aAiTy3qGhttps://www.youtube.com/watch?v=_5N9Fvep… There are multiple approaches. It seems that the sensor swab and sensor gel sticks seem to work the best. Leica uses a pentax gel sticks to remove any extra smudges before camera shipment. The pentax kit is even shown on their home page: https://en.leica-camera.com/Photography/… Good luck!

Thanks Anthony. That seems to be the issue. Appreciate your response.
