My Sony A500 has a dust (or whatever it is) on it as shown in the red circle below. How to get rid of it? It is only 2 months old.
I had changed lens, it is still there. I had blowed the sensor by following the instructions as per http://www.youtube.com/watch?v=Y7lvL1-nktw, still no luck.
By the way, this speck of dust don't appear on my photos, no matter what aperture or zoom that I am shooting.
Please advise if this is something that I can do or need to send back to Sony service center.
