I have an HS10 and I think I have at least two dust blobs. I dont think they are pixel issues because they cover more than one pixel (about thumb size on a 83" diag screen), also, while I cant bring them totally into focus, changing the focus all the way to one end makes the anomally much smaller, sharper and rounder looking. The only reason I wouldnt think its dust is because I've taken the cover off and shot the LCDs with compressed air twice, and they arent going away. Its pretty noticible in dark scenes/movies, as the spots are almost like hotspots, but their not because they change shape and size when I focus/zoom. Am I doing something wrong when I'm trying to blow them off? I thougth it was pretty straight forward.
