    I have noticed that if I de-focus my lens totally on a white blank screen, there are loads and loads of light purple specs, all very tiny, when I re-focus none of the specs are visible at all, I have checked carefully and there are no dust blobs visible whatsoever, from this point this does not cause me any problem to my viewing pleasure at all, is this Just a simple case of minute dust specs magnified to the extreme, must stress that none of the specs are visible when I re-focus to normal and all remain fixed so I assume tey are somewhere inside the lens althoug not visible, Have cleaned the lens correctly too, interested to hear whether any of you guys find this as well, my PJ is a Hitachi PJ-TX 10 with 20 hours, specs were apparent from new.
