The sensors are different both size wise and manufacture wise so there should be no expectation that because white orbs appear on some X10 images they should appear on X100 images (I have not seen any evidence of this on my X100 images).Thanks for your reply. Just wonder, why is the X-10 hidden? It's not the first introduced X sensor cam by Fujifilm.
Why X10 and not (yet) the X100 are suffering from white orbs?
Only Fujifilm knows, sure about that.
