So I dropped my RX100. And I don't remember seeing this pre-drop. It doesn't happen all the time, but in flashless close-up photos. You can see that sudden 'bloom' before the whole thing bokeh's out, but that kind of rainbow fringed effect is ruining a lot of my close-ups. If I shot 40's starlets all day this would be the perfect thing, but for my stuff, not so much. Is this a) Some effect I forgot to turn off (doubt it, reset the thing once) b) A feature of the camera (again, doubt it) c) some sort of easily fixable issue or d) a candidate for a 'cheap, one minor ding, looks like it's working to me' sale?
