[QUOTE="voxmagna, post: 614454, member: 38477"] I've used all the different methods for sensor cleaning/particle removal. Nobody wants to recommend this or that for fear of somebody ruining their sensor which I can understand. I've just ordered a gel stick, but I suspect it will work no better than Blu-Tack on a cocktail stick, which is so cheap it's use once and discard. The slightly wet full frame stick wipes work well to if the rocket blower doesn't move them first. Although I prefer a method that tries to remove spots from the camera rather than move them about inside the body. If you calculate the physical pixel size of a 24Mpix sensor in microns, we should agree you can see a pixel error on a large print or hi res TV monitor and you appreciate just how clean a camera sensor has to be. F22 is only used to identify the foreign bodies more easily. Even at F11 they can still be seen on your shots in plain areas or sky, they are just larger and more diffuse. I can shoot a plain wall indoors lit with tungsten with the highest ISO. Blemishes or foreign bodies on the sensor show up even over the noise and grain. On the top third of landscapes with sky, you see them in the same place on all similar shots during post. [/QUOTE]
