I had it only when using the flash in low light. My flash was not set in place properly. Replaced, on my third and finally all good. Check your flash to see if u can see a black ring around the yellow or looks like some depth is to it.
I have *Heard* That this only occurs when in certain kinds of lighting. Im not sure whether it affects all users or just some.
What do you guys think,Took 2 pics,....one in complete darkness using flash, and one with a 100watt incandecent light on in the corner, and used flash too. Seems to me that its just about perfect without the light on, but has real problems (that I bet can be dialed out with a firmware update) with incandecent lighting.
