Hi I just went to use my 5d-mii and noticed some little spot on the lcd following my movements, that's when i knew it wasn't some dust on the lcd screen. Then i detached the lens and checked on it's ends, all super clean, nothing there. Also not on the front of the lens and there i had a uv-protection anyway. So i was looking into the camera's mirror or sensor, whatever its called. Nothing there really either. I cleaned with a fine cloth and all possible little dust particles were gone. I did this a few times but still the spot looking like a little dust particle is on there when shooting. I tried sensor-cleaning/ dust-busting the data, etc. Nothing worked. I have no idea how this could be possible. Two weeks ago when i used it last time it was all perfectly fine and since then I kept the camera sealed, always in the protective bag and even had some plastic wrap around it What could this be? Nothing so far worked in my attempt to clean and remove it. Any idea? Thanks!
