I gave my old Canon SX230 HS to my friend's son, who has enjoyed using it over the past year or two. But it seems he carried the camera around in his jacket and pants pockets a lot and he now tells me that some pieces of lint are stuck inside the lens. Most of them can't be seen when shooting or looking at finished images - but some can. Are any of the best and brightest at Serious Compacts experienced in removing this kind of dust from the lens of a fixed-zoom compact? I'm about to take my Giotto's Rocket Air Blaster over to my friend's house in an attempt to blow it out. But is blowing air in around the space surrounding the lens even likely to work without disassembling the camera in some way? Believe it or not, in all my years of photography, I have never had this kind of problem. Careful handling and storage of my cameras has helped, of course. EDIT: I'm also going to try vacuuming the front of the camera using a crevice tool. Any advice here?
