I recently noticed that I have a white spec coming out on my pictures. At first I thought it was my lens so when I swapped out lenses and cleaned them as well the spot remained in the same location. The spot can be faintly seen in live view but when you zoom into the pic the spot is there. My GF dropped my camera like 2 months ago but the camera has worked perfect. Could this be a result of the drop ? or dust ? Let me know what you think and I can start figuring it out step by step.
