Hey guys, I need some advice. I just bought a K-5 (from the marketplace here), and while everything looks fine, these two dots in the center of the sensor are really bothering me.
They show up at small apertures, like dust, but they don't look like dust! They have some sort of halo around them, and blower doesn't get them off, neither does in-camera dust shake.
What do you think it is? Should I try cleaning it off, or should I be asking the seller?
I attached the pictures - one's original, the other one is magnified.
