Samsung SL600 Black Dots in viewfinder
When I look through viewfinder I see 3 light spots, as I zoom in they become darker and smaller. The 3 dots show up on pictures also. I have cleaned the viewfinder and the lens, I also took out the battery and the memory card shot air from a can into camera. I put battery back in and left the memory card out the black dots are still there. What are these dots, how can I get rid of them?
